## What is the central ray for the Dorsoplantar projection of the foot?

The dorsoplantar projection is obtained with the child standing, and the tibia should be perpendicular to the film plane. The central ray is angled approximately 15° toward the heel to minimize overlap between the lower leg and the posterior foot.

## What is a Dorsoplantar projection?

The dorsoplantar view is part of a three view series examining the phalanges, metatarsals and tarsal bones that make up the foot.

## Which foot projection and position will demonstrate the metatarsals third through fifth without superimposition?

Ch 6-7 Bontrager

Question | Answer |
---|---|

A radiograph of an AP oblique-medial rotation projection of the foot reveals that the proximal third to fifth metatarsals are superimposed. What type of positioning error led to this radiographic outcome? | Over rotation of foot (toward medial direction) |

## What is the central ray angle for an AP projection of the leg?

Central ray Directed to joint space between patella and femoral condyles at an angle of 25- 30 degrees caudad.

## Which of the following anatomical structures is most commonly affected by gout?

The most frequently involved tissues were synovium, bone, skin, cartilage, tendon, ligament and kidney, with less commonly affected musculoskeletal tissues shown in Table 1 and non-musculoskeletal tissues shown in Table 2.

## What is another name for an AP projection of the foot?

## What is meant by Dorsoplantar?

(dor″sō-plăn′tăr) [″ + planta, sole of the foot] From the top to the bottom of the foot.

## How much do you angle for a foot xray?

Place right and left markers and upright marker on IR. Patient’s weight is distributed equally on each foot. Central ray 10 degrees toward heel is optimal. Minimum of 15 degrees necessary to have enough room to position tube and allow patient to stand.

## What is an axial projection?

Axial projection. Radiographic projection devised to obtain direct visualization of the base of the skull. Synonym: axial view, base projection, submental vertex projection, submentovertical projection, verticosubmental view.

## What is a true lateral position?

The academic rule of a true lateral wrist radiograph is defined by the pisoscaphocapitate relationship, where the palmar cortex of the pisiform should lie centrally between the anterior surface of the distal pole of the scaphoid and the capitate, ideally in the central third of this interval ^{1}.

## What does DP mean in radiography?

There are two main views that are most helpful to the hoof care provider: Lateral-Medial, from the side of the foot, also known as a Lateral Radiograph. Dorso-Palmar, from the front of the foot, also known as a DP or AP Radiograph.

## What is the patient position for a lateral projection of the third fourth or fifth toes?

What is the patient position for a lateral projection of the third, fourth, or fifth toes? a. supine, with the leg & foot laterally rotated.

## Where should the central ray be directed for a lateral calcaneus radiograph?

arrt prep-rad proc1

Question | Answer |
