PH-49 CT Colonography Phantom NCCS
Innovative study tool for safe and effective CT Colon screening.
1. Cylindrical colon units with targets that represent polyps can be set at the position of ascending colon, descending colon and rectum in the life-size lower torso phantom.
2. Four types of colon units are included for evaluation. Each unit has six targets lining in sequence on the inner wall of the unit. Depressed types are to evaluate tumor detection sensitivity and projection types can be used to evaluate volume measurement accuracy.
Depressed l: circle targets with fixed diameter
Depressed ll: circle targets with fixed height
Projection l: half-ellipsoid sphere targets with fixed diameter
Projection ll: half-ellipsoid sphere targets with fixed ratio
3. Contrast agent can be poured into the colon units for tagging.
4. Pencil shaped ion chambers can be inserted in the center of the phantom for CTDI measurement.
-Visualization and detection of targets
-Study on optimal dose for low dose CT colonography
-Evaluation of accuracy of measurement (size, volume>
-Study on optimal density of contrast media
