Select the TRUE statement from the choices below.
a. The art of image critique is the application of scientific knowledge to the analysis of an image.
b. If an image is within acceptable limits, it is always of optimal image quality.
c. Photographic problems involve the production of recorded detail.
d. The cause of an unacceptable or suboptimal image includes technical factors only. - ANSW-a. The art
of image critique is the application of scientific knowledge to the analysis of an image.
Image critique is particularly challenging with current technology due to the problems centering around:
a. patient positioning
b. patient preperation procedures
c. the sophistication of the digital technologies used
d. new xray tube designs providing much higher resolution with decreased heat loading - ANSW-c. the
sophistication of the digital technologies used
Generally speaking, the process of image analysis should start with
a. the formulation of a hypothesis as to cause.
b. a review of the entire image.
c. the identification of patterns or cues.
