At the 2013 annual meeting of the Society of Nuclear Medicine and
Molecular Imaging (SNMMI), June 8-12 in Vancouver, B.C., Canada, Siemens
Healthcare (booth 720) will introduce Biograph mCT Flow – a
groundbreaking new positron emission tomography/computed tomography
(PET/CT) system that, for the first time ever, overcomes the limitations
of conventional bed-based PET/CT with FlowMotion, a revolutionary new
technology that moves the patient smoothly through the system’s gantry,
while continuously acquiring PET data. Biograph mCT Flow with FlowMotion
takes routine image quality to a new level by enabling imaging protocols
based on the organ’s need. FlowMotion expands accurate and reproducible
quantification in all dimensions for precise disease characterization in
therapy monitoring, while enabling physicians to offer as low as
reasonably achievable (ALARA) dose to every patient. Additionally, the
combination of a 78 cm bore with five-minute ultra fast scanning and a
continuous sense of progress throughout the scan provides the patient
with a more comfortable exam experience. The new Biograph mCT Flow
PET•CT system with FlowMotion technology demonstrates Siemens’
innovation and competitiveness— key components of the Healthcare
Sector’s Agenda 2013 two-year initiative.

“Siemens is proud to usher in a bold new era of PET imaging with the
Biograph mCT Flow PET•CT system,” says Dr. James Williams, CEO of the
Molecular Imaging business unit at Siemens Healthcare. “The system’s
FlowMotion anatomy-based scanning approach helps enable physicians to
make a more confident diagnosis based on high quality images for each
patient, as well as accurate and reproducible quantification for
treatment planning and monitoring.”

Finest detail in every organ*

Every organ in the human body is unique, with some presenting additional
barriers to obtaining the necessary image quality to support confident
diagnoses. With conventional PET/CT scanners, planning and scanning is
limited to the fixed size of the system’s detector field of view (FOV)
for each bed position. While the adjustment of scan parameters in
clinical stop-and-go PET/CT protocols is technically possible, the
complexity of adjustment has limited its routine use.

Fundamentally changing how PET imaging is performed, Biograph mCT Flow
PET•CT with FlowMotion technology eliminates the need for stop-and-go,
bed-based planning with planning and scanning based on the single
continuous motion of the patient table. Without the limitations of bed
positions, the technician can be easily adjust the examination
parameters such as speed, image resolution and motion management to the
precise dimensions of organs and routinely incorporated into a single
scan for every patient.

Accurate quantification in all dimensions

In order to help physicians make sound decisions, imaging must provide
accurate and reproducible quantification. Conventional PET/CT suffers
from intrinsic sensitivity degradation from the center to the edge of
the axial FOV. Overlapping sequential bed positions are used to
compensate for this constraint, but this approach can lead to axially
varying noise sensitivity. This noise can distort the quantitative
values of a detected lesion, which may prompt a physician to
mischaracterize the severity of a tumor. By continuously moving the
patient through the detection system, FlowMotion technology eliminates
overlapping bed acquisitions and maintains uniform noise sensitivity
across the entire scan range.

Minimum dose and maximum speed

Two of the most challenging issues facing healthcare today are the dual
mandates to improve patient safety and increase productivity.
Conventional PET/CT systems often require clinicians to choose between
protecting patients through lower dose and enhancing productivity
through faster scans.

FlowMotion eliminates CT dose due to overscanning by enabling the user
to precisely define the beginning and end of the PET scan – and since
the CT scan of Biograph mCT Flow begins and ends at the same points as
the system’s PET scan, the patient is not irradiated in areas of the
body that do not require a CT scan. With Biograph mCT Flow, the user can
realize a CT dose reduction of up to 32 percent. Meanwhile, the new
Biograph mCT Flow, coupled with TrueV, is the only solution that enables
continuous scanning at twice the speed of conventional PET/CT. TrueV
technology provides a 30 percent wider axial FOV of 21.6 cm—the largest
in the PET/CT industry**— enabling Biograph mCT Flow to provide a 70
percent increase in count rate performance. When combined with
ultraHD•PET, which delivers increased image quality, routine clinical
scans can be performed in five minutes. Throughput is further enhanced
by one click FAST planning. The user can employ a simple protocol setup
to determine the scan type and duration for up to four zones—for
example, the head, lungs, abdomen and legs. The user can then tailor the
scan in each region using Siemens’ established image quality techniques.

Open comfort for all*** patients

Healthcare providers require a system that accommodates the individual
needs of a wide patient demographic. A standard PET/CT scan can last 25
to 30 minutes, with the patient frequently falling asleep or zoning out
while the system acquires a bed position. When the bed shifts to the
next scanning position, the patient is often startled, resulting in an
image that is marred by motion artifacts. The patient also can feel
anxiety during the lengthy scanning process, perceiving no progress
until the bed shifts to a new scanning position.

In addition to the elimination of patient motion due to surprise, the
continuously moving patient table of Biograph mCT Flow gives the
patients a sense of progress, which can further enhance patient
satisfaction. Additionally, the large 78 cm bore, short tunnel and a 227
kg [500 lb] table capacity can improve patient comfort and accessibility.

Launched in November 2011, Agenda 2013 is the initiative of the
Siemens Healthcare Sector to further strengthen its innovative power and
competitiveness. Specific measures, which will be implemented by the end
of 2013, have been defined in four fields of action: innovation,
competitiveness, regional footprint, and people development.

The Siemens Healthcare Sector is one of the world’s largest suppliers to
the healthcare industry and a trendsetter in medical imaging, laboratory
diagnostics, medical information technology and hearing aids. Siemens
offers its customers products and solutions for the entire range of
patient care from a single source – from prevention and early detection
to diagnosis, and on to treatment and aftercare. By optimizing clinical
workflows for the most common diseases, Siemens also makes healthcare
faster, better and more cost-effective. Siemens Healthcare employs some
51,000 employees worldwide and operates around the world. In fiscal year
2012 (to September 30), the Sector posted revenue of 13.6 billion euros
and profit of around 1.8 billion euros. For further information please
