A PA axial oblique (RAO) large intestine image demonstrates an obscured right SI joint and closed left obturator foramen. Such an image: 1.was obtained with the patient rotated more than the required amount.2.also demonstrates the inferior aspect of the left acetabulum superior to the distal rectum.3.was obtained with the central ray angled less than the required amount.4.was obtained with the patient rotated less than the required amount.

To increase spatial resolution, what would need to happen with pixel pitch and pixel density?

A cephalic central ray angulation is required on an AP knee image when the: 1. examination is performed with the patient in an upright position 2. patient’s anterior tibial margin is distal to the posterior tibial margin 3. the patient’s ASIS-to-imaging table measurement is 22 cm 4. the knee is flexed and a curved IR is used

A reference histogram that evolves by averaging it with the previous 50 procedures is called a(n) _________ histogram:

For an AP atlas and axis image: 1.the mandibular angles and the shoulders are positioned at equal distances from the IR2.the acanthiomeatal line is aligned parallel with the IR3.a 5-degree cephalad angulation is used4.an imaginary line connecting the upper occlusal plane and posterior occiput’s inferior edge is aligned perpendicular to the IR

If quantum mottle appears on the digital image, what should be done?

What radiology descriptor relates to the efficiency of the detector to convert x-ray energy into a radiographic image?

A recommended practice is to decrease the SID to less than 40 in (100 cm) for the oblique sternum to increase the magnification and resultant unsharpness of overlying ribs.
