Manual coordinate calculation for the Breast
BI 7 MR Coil Set
On the following pages you will find instructions for the manual coordinate calculation of the BI 7 Post & Pillar
and Grid Biopsy Method, which is located on the user interface of your Siemens MR-system.
Besides the manual calculation of coordinates, additional solutions for software-supported coordinate calcu-
lation are offered by third-party providers.
Please contact NORAS or your Siemens representative directly if you have any questions regarding compatibi-
lity and application.

Manual coordinate calculation for the Grid Biopsy
System
In the following the Grid localization process with medial/lateral access
while using sagittal imaging slices is b
riefly described.
The grid pattern itself is used to locate the position of the lesion.
The grid plate is mounted on the biopsy unit for the fixation of the breast. The pattern of this grid is visible on the
sagittal MR-image at the edge of the breast. Therefore the grid position lying directly in line with the lesion can be
identified manually. A needle block is inserted into that grid position.
The lesion is marked by using the imaging tools on the scanner user interface, e.g. a circle or a cross. This marking
is copied and pasted into the parallel sagittal slice, which shows the grid pattern. Now it can be easily seen, where
the needle block and the needle need to be positioned. Additionally, a MR-visible marker block for better orienta-
tion on the grid can be used (in this imaging example, the marker is sitting in the middle of the grid).
With the knowledge of the number and thickness (plus a potential gap between slices) of the sagittal imaging
slices from the surface of the grid to the lesion, the penetration depth can be easily calculated.
21Uni-Lift Prostate Intervention Device
for MR-guided interventions of the prostate
Uni-Lift Prostate Intervention Device 118330
PROSTATE
The Uni-Lift is designed as an arc in which the legs are mounted
on brackets. The arc is adapted to the MR table and to the bore
size, thereby preventing abutting of the legs while providing
the maximum available space for intervention.
The supine position allows transperineal access for biopsy and
therapy of the prostate.
As an application example a biopsy grid for transperineal access
is shown.

TION
The flexible 120 cm (47.24 in) long and 32 cm (12.6 in) wide
coil is designed so that it can wrap around both hips, ab-
domen and chest. The coil size is designed for optimal
penetration depth to the body center. Due to a fixation
system using two belts, the coil can be positi-
oned very close and stable to the desired anatomy.
The coil is designed for diagnostic images of the pro-
state or internal organs (liver, kidney, etc), as well as
MR-guided interventions, which can be performed th-
rough integrated biopsy windows inside the coil plane.
A biopsy unit with angulation possibility was specifically developed
for the Uni-Belt coil. It can be easily attached inside the coils’ biopsy
windows. Biopsies of prostate, liver, kidney, spinal cord etc. can be
performed through the steam sterilizable and reusable biopsy unit
made out of PEEK material.
The advantage of the NORAS Uni-Belt is given by the arrangement
of its single elements combined with the complete covering of the
examination area. Futhermore, a better adapting to the anatomy
has positive effects on the result of measurement.

The „Variety“ Coil is a 16-channel multipurpose array, which has been developed for high flexibility during examination of challenging anatomic
regions. A good example for such areas is the imaging of musculoskeletal areas.
VARIETY
High signal quality based on a design with 8+8 array elements
with high coil element density
High resolution examinations of even small body regions with
reduced scan durations
High speed image acquisition due to the possibility of accele-
rated imaging in all directions
Application for diagnosis in orthopedics, pediatrics and in
veterinary medicine
Enables motion studies of all joints

through dedicated positioning aids (optimal image quality)
• Compatibility with Siemens coil portfolio
NEW: Siemens Coil File available* • No need to remove the spine coil anymore
* Only applies for Siemens Skyra 3T and Aera 1.5T customers
Each half of the coil is based on an 8-channel array, which can be used separately as a surface array for coverage of various body areas. The indivi-
dual coil elements in each array have a small diameter of approximately 7 cm. This design results in a high signal quality, which allows for highest
achievable resolutions.
Based on the high mechanical FLEXIBILITY and on the small size of its array elements the “Variety“ covers a much larger field of applications for high
resolution imaging in comparison to standard flexcoils. Through the use of Velcro® strips and dedicated positioning aids the “Variety“ Array can be
adjusted very well to curved anatomical regions.
The Variety 16-Channel Multipurpose Coil from NORAS MRI products is compatible to all Siemens Tim® systems. NORAS is currently working on
compatible solutions for other manufacturers of MR-scanners. Kindly contact us in case you have any questions regarding the compatibility of the
NORAS 16-Channel Multipurpose Array for your scanner.
24Typical Applications and Positioning Aids - Orthopedics
Hand and Wrist
VARIETY
The size of the coil halves enables imaging of the whole hand and wrist.
A special positioning aid, in which the bottom coil half can be placed, creates a sta-
ble and flat surface to put the hand on.
If needed, the second coil half can be put on top of the hand.
Alternatively, the hand can be positioned “standing up“ using our elbow positio-
ning aid (see illustration below right).
Elbow
For smaller elbows (e.g. kids) a single coil half can be used to be wrapped around the
elbow. This coil half can then be fixated using Velcro® strips.
For bigger elbows, the size adjustable positioning aid can be used.
25Shoulder
A special sloped positioning device allows comfortable support on the lower coil
half.
For fixation of the upper coil half, you can use e.g. sandbags.
VARIETY
Knee, Foot and Ankle
The stageless adjustment of the positioning device allows for proper support of pa-
tients with a body size of up to 2.1 m and for knees with high or low volume.
The flexible design also allows imaging in flexed and stretched position. Further-
more, an optional supporting element for imaging in flexed position is available.
We advise to use always the positioning aids in combination to enable support and
less motion of the patient.

32Intraoperative Neuro-
surgery solution from
NORAS
As early as 2005, NORAS MRI products GmbH presented the
first MR compatible head holder with receiving coils and was
thus the pioneer in the field of intraoperative MRI imaging in
the field of neurosurgery. With the innovative head holder
NORAS was able to quickly establish a leading position in
NEURO
neurosurgery solutions.
Based on a creative and respectful cooperation with leading
neurosurgeons from Germany, Switzerland, the US and Ca-
nada NORAS has created the head holders FLEXIBILITY and
HEIDBERG in 2013.
The head holder HEIDBERG became a strong alternative to
older versions of NORAS head holders. Both head holder sys-
tems convince besides excellent image quality with a unique
sterile concept and an optimized workflow.
The constant innovations are based on requirements, ideas
and challenges that leading neurosurgeons experience in
their everyday work.
The increased reliability and high availability of the Head
Holders FLEXIBILITY and HEIDBERG are proven in e.g. yearly
more than 200 successfully completed cases in Europe using
these advanced systems for MR-based neurosurgery.
Thanks to ongoing enhancements and innovations, NORAS
belongs to the drivers of intraoperative MR imaging.
This was proven again in 2018: The new LUCY head holder
combines years of experience in the field of MRI with new
applications thanks to its CT compatibility.
With constant innovation and new developments the NO-
RAS MRI products Ltd is a reliable partner for MR-supported
neurosurgery.
33OR Head Holder LUCY & OR Head Coil 1.5T / 3T

for Siemens Magnetom Aera 1.5T & Skyra 3T/
Philips Ingenia 1.5T & 3T, Ingenia Ambition
1.5T & Ingenia Elition 3T*
LUCY is an innovative neurosurgery solution that combines the
functions of a head holder for secure fixation of the skull during
interventions and a MR coil for intra-operative imaging.
The head holder is compatible with the established 8-channel
NORAS head coil setup. Thanks to the radiotranslucent material,
the OR Head Holder LUCY (without the NORAS OR Head Coils)
can also be used in the X-ray environment – CT and angiogra-
phie – for intra-operative imaging. Besides tumor resections,
„deep brain stimulations” (DBS) and minimally invasive pitu-
itary surgery, the system also supports awake craniotomies.
The NORAS OR Head Holder LUCY and the NORAS OR Head Coil
1.5T / 3T can be used with the MR systems Siemens Magnetom
Aera / Skyra together with the Combi Dockable Table. Due to
NEURO
the compatibility to the new transferboard from Maquet our
solution can be combined with the nexaris Angio-MR-CT and
the Artis pheno Angiography System.
Furthermore, the OP Head Holder LUCY and the NORAS OP
Head Coils can be used with the Philips MR systems Ingenia 1.5T
and 3T, Ingenia Ambition 1.5T and Ingenia Elition 3T.
* Please contact us if you have any questions about the compatibility of the OR head holder LUCY and the
head coil of NORAS.
The design allows a positioning of the patient in prone, supine or lateral position on the OR table.
The head frame of the NORAS OR Head Holder allows exact adaptation to the patient‘s head size. For
optimal access to the area of intervention, the head frame can be pivoted, rotated, tilted and adjusted in height.
A secure attachment of the patient‘s head is ensured by the three-point fixation. With the help of the
integrated force indicator, the required clamping force can be checked exactly.
The entire system is height-adjustable to achieve optimal patient positioning in 70 cm bores (Siemens/ Philips) as well
as in Siemens CT scanners. In addition, the entire structure can be moved along the head-foot-axis and the horizontal
axis.
The NORAS 2x4 Ch coil concept, with the ability to position the both coils close to the head, provides excellent
image quality.
The OR Head Holder LUCY can be used in combination with the nexaris Angio-MR-CT and the Artis pheno Angiography
System.
LUCY is compatible with various surgical equipment (e.g. GREENBERG™, VarioGuide™, LEYLA retractors) and supports the
navigation system of Brainlab.

Due to this concept, there is no need to sterilize the co-
ils and cables.
During the development process, NORAS emphasized
that the coils and cables as well as most components
of the Head Holder can be used in an unsterile environ-
ment. The basic concept is to create a sterile chamber
in between the patient’s head and the top coil with two
sterile OR drapes.
A compatible version of the reference star and head
holder adapter has been developed in collaboration
with BrainLab AG. The reference star can now be tightly
attached to the head holder without perforating the
sterile OR drapes.
This sterile concept is offered to all existing customers
as an upgrade kit HEIDBERG.

Fixation Concept
There are now three mounting points for height-adjus-
table bottom pins. For the upper pins, a combination
of one 2-point fixation and a 1-point fixation or two
2-point fixations can be mounted on each side of the
head frame. This enables flexible pinning combinations
in consideration of all patient positioning options.
Clamping Device with Force
Indicator
The Clamping Device with Force Indicator allows the
surgeon to apply a defined pinning force during fixati-
on of the patient‘s head. Once the desired force is rea-
ched, the fixation rod is tightened up by a lock lever and
the clamping device can be removed.

Head Holder SI7300
For Siemens Magnetom Espree, Symphony and Verio with Rotating Table
The NORAS Head Holder SI7300 has been exclusively developed for the Siemens MAGNETOM systems with rotating table. This combination allows
lateral left or right patient positioning. Numerous variations of surgeries are possible, e.g. awake craniotomies in lateral position are feasible. Besides
the standard components, further special components are available for the SI7300.

Head Holder 113056 // Head Holder 113066 (Version 4)
for Trumpf Miyabi Shell for Maquet bearing 1180-71A0 and 6042-01C0
The NORAS Head Holder 113056 has been developed for the use with the Trumpf OR table Jupiter in combination with the Siemens Neuro Miyabi
Shell for Siemens 1.5T and 3T MR systems (Espree, Symphony, Avanto, Verio, Trio). The NORAS Head Holder 113066 has been developed for use with
the Maquet bearing 1180-71A0 and 6042-01C0 for Philips Achieva 1.5T and 3T MR systems.
In contrast to the previous Head Holders SI7000 and SI7000-MQ, a new sterile concept has been realized. During the development process, NORAS
emphasized that the coils and cables as well as most components of the Head Holder can be used in an unsterile environment. The basic concept
is to create a sterile chamber in between the patient’s head and the top coil with two sterile OR drapes. For this reason, only one top array coil is
required. Furthermore, the bottom array coil can now be removed for better access during the intervention.

44NORAS Product
Development
NORAS has small administrative procedures due
to the small size of the company. This results in
development processes being able to be adjus-
ted quickly and accurately per the customer’s re-
quest. Nevertheless, all necessary departments
for MR coils and MR equipment are located in
one building.
Starting with the mechanical development and
the coil development department, continuing
with the creation of a prototype and the stress
tests up to the approval as a medical product,
everything is being done in exceptional team
collaboration.
In the in-house coil R&D department new coil projects
are being processed and already existing coils are
being advanced according to the state of the art.
45All of the mechanical develop-
ments, from the phase of plan-
ning up to series production
are being edited on our 3D-CAD
System (Solidworks).
Mechanical adjustments and
quick developments of proto-
types are also being performed
in the in-house department,
besides the collaboration with
different development partners.
46PRESS REPORTS AND STUDIES
HYPMED
Innovative Breast-cancer research project HYPMED from NORAS MRI products GmbH gets EU
funding over six million euros. Reviewers explicitly praise the scientific and clinical potential of the
proposal.
Würzburg/Brüssel, 07.09.2015 – The from NORAS supported and led by Uniklinik RWTH Aachen project proposal HYPMED (develop-
ment of a hybrid MRT/PET-system for diagnostics of breast cancer) achieved top marks from the reviewers of the EU-program „Horizon
2020“ and unlimited funding recommendation. The innovative concept was praised by the reviewer commission: „The project has an
extremely high potential. We expect, that the new approach of the HYPMED project will lead to earlier and better diagnosis of breast
cancer by using determined MR/PET-imaging.“
„The HYPMED-project combines medical competence and physical-technical competence as well with engineering expertise in an
ideal matter. It shows what potential the Uniklinik RWTH Aachen has in the field of medicine and technology “, highlights the project
leader, Univ.-Prof. Dr. med. Christiane Kuhl, director of the clinic for diagnotic and interventionel radiology at Uniklinik RWTH Aachen.
Together with the RWTH Aachen and other partners from all over europe NORAS will work on the HYPMED project. The Horizon
MEDIA
2020-program is highly competetive; only two percent of the submitted proposals receive funding. It is extremely exceptional to score
with full points from the reviewers in such a competition.
Diagnose breast cancer earlier and improve treatment
Breast cancer is still the leading cause of cancer related deaths among women. That’s why the search for new possibilities to diagnose
the illness in an early state and to treat it is still in the focus of scientific research nowadays. The HYPMED-project aims to develop a
new device for medical imaging based on the basic science of physics over the engineering implementation into the clinical test. The
new device will deliver a so far not possible combination of breast-MRI and PET (positron emission tomography) thus pushing the
frontiers globally in breast cancer research. “With the new device every conventional MR-system can be become a so called hybrid
system if needed. It will allow us to recognize even the smallest changes and improve the assessment of tumor aggressiveness”, elabo-
rates Prof. Kuhl. “Such imaging modalities are desperately needed for a targeted treatment”. This is not only true for breast cancer. The
new concept will also allow for other diseases new diagnostic possibilities. “With the success of the HYPMED-project a new chapter in
medical imaging will be written”, says Prof. Kuhl
