In addition to the regional/unit exams, you will have all of the following assignments except:

If the radiographer is unable to achieve a short OID because of the patient’s body habitus, which of the following adjustments can be made to minimize magnification distortion?

An object is projected using a SID of 180cm and a SOD of 135cm. If the projected image measures 20cm in length, how big must the object have been?

__________ is a shape distortion in which the length of the image measures shorter than that of the real object from a tilt.

Which one of these is a controlling factor for contrast?

Information missing from underexposure such as mottle, which reduces the signal to the IR can:

T/F: Small mA stations will produce less unsharpness than large mA stations.

T/F: The breaking effect for the spinning anode is when the induction motor runs in reverse.

Find OID if SID is 40″ and SOD is 27″.

A marble measures 3.4 inches on a radiograph.  The actual size of the marble is 0.8 inches.  What is the percent of magnification for the foreign body seen in the patient’s stomach?
