Computed tomography questions with
correct answers 100% sure.
CT scan ANS - Process of making cross-sectional tomographic image
Produces transverse or axial images
Tomography meaning ANS - Cut or slice, one plane of body clearly while others are eliminated
Advantages of CT ANS - Overcomes superimposition of anatomy
Sensitive to small differences in tissue
CT fundamentals ANS - X-ray tube rotates around body, detector assembly measures radiation,
computer piles attenuation data, image displayed as slice
CT image receptor ANS - No conventional image receptor
Uses detector assembly
CT gantry ANS - Angled 30° in 2 directions
Central opening or aperture
Table linked to gantry
CT Collimator ANS - Reduces dose + improves image quality
2 collimators: pre patient & post patient
CT images features ANS - no superimposition, differentiates between densities, reduces image scatter,
high res image contrast
Advantages of CT ANS - 3D imaging, multiplane reformatting, used for multiple applications
