Answer 26

Subject-to-image receptor distance (SID)

Question 27

Deviation from true sahpe

Answer 27

Shape Distortion

Question 28

The shape distortion of the body part must be analyzed and the primary controlling factors must be studied

Answer 28

1. Alignment of body part 2. Central ray direction 3. Anatomic part 4. IR placement 5. Angulation of XRT

Question 29

Discuss Display of Radiograph

Answer 29

Should be mounted in a view box/ illuminator/ negatoscope for proper viewing following the normal orientation of the body or normal anatomic position to identify properly the location of the pathologic condition
