___________ is the mathematical process used by single row detector scanners to
reconstruct CT images from raw data
A.) Weighted Averaging
B.) Filtered back projection
C.) The Fourier Transform
D.) Integration of the area under the curve - answerB.) Filtered Back Projection
MDCT scanners capable of collecting 64 slices in a single rotation do NOT:
a. perform conventional CT scans
b. perform helical CT scans
c. use filtered back projection as their method of image reconstruction
d. perform localizer scans - answerC.) Use Filtered back projection as their method of
image reconstruction
MDCT scanners most certainly perform localizer, conventional and helical scans
The x-ray beam used in CT scanning is ________ the patients tissues
1.) Reflected off of
2.) Attenuated by
3.) Generated by
A.) 1
B.) 2
C.) 3
D.) 1, 2 & 3 - answerB.) Atteunated by
A retrospective reconstruction, in which the reconstruction field of view is varied, uses:
A.) A reconstructed image in a sagittal plane
B.) CT Raw data
C.) More Photons
D.) CT Image data - answerB.) CT Raw Data
Retrospective reconstruction always utilizes the unprocessed CT data.
CTA images come from a _____ scan.
1. conventional, or serial
2. helical
3. localizer
a. 1 only
b. 2 only
c. 3 only
d. 1, 2 & 3 - answerB.) 2 only
, The actual attenuation data measured by the detectors from all projections during a
scan is contained in CT _______ data
1.) Image
2.) Convolved
3.) Raw
A.) 1
B.) 2
C.) 3
D.) 1, 2 & 3 - answerC.) 3
The CT raw data contains the attenuation coefficient information gathered through the
detectors measurements of the photons which passed through the patients body.
Using ____ reconstruction filter would decrease the appearance of noise in a CT image.
1. no
2. a sharp
3. a smooth
a. 1 only
b. 2 only
c. 2 & 3
d. 3 only - answerD.) 3 only a Smooth
A kernel is a _______
A.) Component in the x-ray tube
B.) Post-processing filter applied to image data
C.) Type of detector
D.) Filter applied to the CT rawdata - answerD.) A kernel is a filter applied to the CT
RAW data
A kernel also called a reconstruction filter or a convolution filter
Iterative reconstruction is:
A.) The type of image reconstruction method used in CT before mutlirow detector
scanners became available
B.) A complex cycle of correction calculations applied during image reconstruction in
order to reduce noise
C.) A second reconstruction process performed after the initial reconstruction in which a
set of modified parameters is used
D.) Typically performed on helical image data, to generate image orientations other than
those that can easily be directly acquired with CT - answerB.) A complex cycle of
correction cacluations applied during image reconstruction in order to reduce noise.
Iterative reconstruction is a fairly new recent advancement in CT
From which of the following can the most diagnostic multi planar reconstructions be
generated?
