Multislice HELICAL CT SCANNER
APPLICATION
Activion
TM
16 is a 16-slice Helical CT system that supports
whole-body scanning.
The system generates a minimum of 32 slices per 1.5 sec-
onds using the Selectable Slice-thickness Multirow
Detector (SSMD).
In addition, the high-speed rotation mechanism and the
fast reconstruction unit of the system allow quick image
acquisition to further improve throughput in CT examina-
tions.
FEATURES
• Multislice detector
Detection elements with high-power and uniform output
characteristics enable a minimum slice thickness of 0.5
mm, and accurate isotropic data can be acquired.
The adoption of the SSMD method means that high-
speed as well as high-resolution scanning are support-
ed.
The minimum slice thickness is reduced to 0.5 mm, mak-
ing it possible to select the desired slice image for scan-
ning from among 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm,
and 5 mm, depending on purpose.
• High-speed scan
Data for 16 slices can be acquired simultaneously in
each scan. For example, scanning of the lung fields
over a range of 30 cm at a slice thickness of 1 mm can
be completed in 10 seconds or less.
Since the acquisition is completed in a short period of
time, this obviously alleviates the burden on the patient,
but also improves throughput by eliminating the need to
wait for the X-ray tube to cool down.
• High-quality images
It is now possible to use thin-slice helical scanning for
routine examinations. Based on high-resolution voxel
data, smooth and finely-detailed 3D and MPR images
can be obtained with the same size in the X, Y, and Z
directions (isotropic). In CT cerebral angiography, for
example, scanning over a range of 40 mm at a slice
thickness of 0.5 mm can be completed in 4 seconds and
image processing (such as 3D, MPR, or tomographic
image processing) can be performed for a single volume
acquisition dataset through simple operations.
In addition, by stacking the data acquired using thin
slices, images with reduced partial volume effects can
be obtained.
• Outstanding operability
Operability is improved as described below.
– In 3D image processing or time-consuming image pro-
cessing such as for regions in which calcified areas are
superimposed on contrast medium, bone elimination
can be performed easily while observing reference
images.
– Most 3D images can be generated using the optimal
conditions by simply selecting an appropriate preset
icon.
• Selectable image slice thickness
It is possible to acquire the data for routine examination,
detailed examination and to generate 3D images in a sin-
gle scan.
For example, by performing a helical scan with a 0.5-mm
slice thickness, it is possible to generate images at vari-
ous slice thicknesses from the same data, such as 10-
mm slice images for routine examinations, 5-mm slice
images for detailed examinations, and 0.5-mm slice
images for generating 3D images. It is also possible to
set the image slice thickness with multiple ranges.
For example, by performing a helical scan of the head
with a 0.5-mm slice thickness, it is possible to generate
images with optimal slice thickness for each region in a
single reconstruction, such as 5.0-mm slice images for
the cranial base as well as 10-mm slice images for the
cerebral parenchyma.
• Exposure reduction
This system incorporates the quantum denoising soft-
ware (QDS) as a standard function, which is effective for
reducing patient exposure.
The QDS is an adaptive filter that can recognize recon-
structed objects. It can perform sharp filter processing
for regions where the degree of change is high, such as
tissue borders; and smooth processing for regions where
the degree of change is low (close to uniform). This
makes it possible to further improve the quality of images
acquired using normal dosages, and improves the quali-
ty of images acquired with small dosages to an image
quality level obtained with normal dosages. As a result,
it is possible to reduce the exposure dose for the patient,
since the scanning can be performed using the optimal
dose for the expected image quality.
