As the image intensifier’s FOV is reduced, how
is the resulting image affected?
In 45 degree medial oblique of ankle:
Tibiofibular joint is visualized & plantar surface should be vertical
List in order of proximal to distal:
Patient PA, MSP parallel with grid, OML 37
degrees to IR, CR perpendicular and exiting the acanthion, what’s best demonstrated?
Which quantity of filtration is used in mammo?
0.5 mm Al (smallest one)
What terms are used to express resolution?
Line – spread function & line pairs per millimeter
Use of a portion of the input phosphor during
fluoro, rather than the entire input phosphor will result in:
Magnified image and improved spatial resolution
Secondary center of ossification in long bones
AP projection of the scapula:
Patient arm is abducted at RT angle to body
Patient elbow is flexed with hand supinated
Exposure is made during quiet breathing
A spontaneous fracture most likely would be associated with
A flat and upright abdomen is requested on an acutely ill patient, to demonstrate the presence of air-fluid levels. Because of the patient's condition, the x-ray table can be tilted upright only 70° (rather than the desired 90°). How should the central ray be directed?
