Radiograph identification

Question 1

Important information used to identify radiographs.

Answer 1

1. Date
2. Patient details
3. Anatomical marker
4. institution identity
5. Patient position

Question 2

Anatomic side marker rules

Answer 2

Should not obscure the anatomy

Should placed at the collimated boarder of the radiograph

Should not obscure patients information.

In PA projections, the markers should be reversed

In radiographs that show both side, include the right marker only

Question 3

Specific marker placement recommendations

Answer 3

• for lateral projections of the head and trunk, mark the side closest to the IR
• For oblique projections that include both sides, mark the side closest to the IR , e,g if its the right side put R.

Question 4

Placement and orientation of anatomy on the
image receptor

Answer 4

• long axis of the anatomy should be parallel to the long axis of the IR
• the anatomical structure must be centred on the IR
• The body must be adjusted in position interms of oblique projections.

Question 4

Conditions through which CR is angled

Answer 4

• when avoiding superimposition of over and underlying structures.
• when avoiding superimposition of curved structures.
• when projecting through angled joints e.g knee and lumbosavral joints.
• when projecting through angled structures.

Question 4

FFD affects which factors

Answer 4

i. Magnification of the anatomy on the image
ii. The spatial resolution
iii. The radiation dose to the patient

Question 5

Pre-exposure Instructions and technical factors

Answer 5

After positioning the patient should be given chance to practice the instructions given.
