An imaging department, having difficulty obtaining acceptable tangential patella images, has opted to have the post processing mode set to "fixed" for all patella images. Why is this a good choice?
A. Fixed mode does not recognize collimation borders.
B. Fixed mode works well for exams where it is difficult to center the image on the image receptor (IR).
C. Fixed mode ignores exposure index (EI) and is useful for body parts with a prosthesis.
D. Fixed mode compares acquired data to a histogram and chooses appropriate brightness and contrast. - Answer>>> B. Fixed mode works well for exams where it is difficult to center the image on the image receptor (IR).
A radiographer is performing a forearm exam on a patient with advanced Parkinson's Disease. Which Technical factor adjustments should be used?
A. Decrease the milliampere-seconds (mAs) from normal to compensate for decreased bone density.
B. Decrease the exposure time to reduce risk of patient motion.
C. Increase the kilovolts peak (kVp) from normal to compensate for increased bone density.
D. Increase the mAs from normal to compensate for increased tissue attenuation. - Answer>>> B. Decrease the exposure time to reduce risk of patient motion.
Which CR orientation is recommended for a radiographic image of the contrast-filled urinary bladder with the patient in the supine position?
A. 2 inches inferior to the pubic symphysis with a 10 to 15 degree cephalad angle
B. 2 inches superior to the pubic symphysis with a 10 to 15 degree caudad angle
C. 1 inch proximal to the tip of the coccyx with a 10 to 15 degree cephalad angle
D. 1 inch distal to the tip of the coccyx with a 10 to 15 degree caudad angle - Answer>>> B. 2 inches superior to the pubic symphysis with a 10 to 15 degree caudad angle
