Description

What is the central ray for the AP projection of the distal humerus with the elbow in partial flexion? Perpendicular to the humerus, traversing the elbow joint

Perpendicular to the metatarsals entering the base of the third metatarsal.

How should the distal humerus be demonstrated in the AP projection of the distal humerus with the elbow in partial flexion? Without rotation or distortion

metatarsals for a shoot-through lateral projection of the foot? A slight cephalic angle.

How can the beam be angled to aid in superimposing the

Where is the knee joint located? How should the elbow joint be demonstrated in the AP projection of the distal humerus with the elbow in partial flexion? Closed. What is the central ray for the AP projection of the proximal forearm with the elbow in partial flexion? Perpendicular to the elbow joint and long axis of the forearm. How should the radial head, neck, and tuberosity be demonstrated on the AP projection of the proximal forearm with the elbow in partial flexion? Slightly superimposed on the proximal ulna

1.3 cm (1/2”) inferior to the apex of the patella. What is the central ray for the axiolateral projection of the hip (shoot-through lateral)? Perpendicular to the long axis of the femoral neck. For the axiolateral projection of the hip (shoot-through lateral), the femoral neck should be demonstrated without overlap from which structure? Greater trochanter (also soft tissue shadow of the unaffected thigh). For the axiolateral projection of the hip (shoot-through lateral),

How should the proximal radius and ulna be demonstrated on the AP projection of the proximal forearm with the elbow in partial flexion? Without rotation or distortion. How should the elbow joint be demonstrated on the AP projection of the proximal forearm with the elbow in partial flexion? Partially open

where should the ischial tuberosity be demonstrated? Below the femoral head. What is the central ray for the modified axiolateral projection of the hip? Directed 15 degrees posteriorly and aligned perpendicular to the femoral neck and grid IR. For the modified axiolateral projection of the hip, how must the IR be positioned? Tilted back 15 degrees. (Perpendicular to the CR, parallel to the femoral neck)

What is the central ray for the AP projection of the distal humerus with the elbow in acute flexion? Perpendicular to the humerus, approximately 5 cm (2”) superior to the olecranon process.

What is the central ray for the AP oblique projection of the hip (Judet method) for the internal oblique? Perpendicular to the IR and entering 5 cm (2”) inferior to ASIS of the affected side.

What is the central ray for the AP projection of the proximal forearm with the elbow in acute flexion? Perpendicular to the

What is the central ray for the AP oblique projection of the hip

flexed forearm, entering approximately 5 cm (2”) distal to the olecranon process.

(Judet method) for the external oblique? Perpendicular to the IR and entering at the pubic symphysis.

What is the central ray for the AP oblique projection of the shoulder? (either one)

Which AP oblique projection of the hip (Judet method) will best demonstrate the iliopubic column and the posterior rim of the

Theory: Perpendicular to the scapulohumeral joint. AHS: Perpendicular exiting the mid-medial border of the scapula. How do you direct the CR for the AP projection of the foot

affected acetabulum? Internal oblique Which AP oblique projection of the hip (Judet method) will best demonstrate the ilioischial column and the anterior rib of the acetabulum?

(adaptive)?

External oblique

How would you direct your central ray for an AP projection of the atlas/axis (Fuchs) if the patient is on spinal precatautions? Parallel to the plane formed between the mentum and the mastoid tips entering just distal to the mentum. What degree of angulation of the central ray, and in which direction, would be required to demonstrate the petrous ridges in the lower third of the orbit on an AP Projection of the facial bones if the patient’s neck is extended and the OML is at a 5 degree angle from vertical? 10 degrees cephalad Jeff Jefferson is on spinal immobilization precautions and requires a frontooccipital projection (Towne’s View) of his skull. His head is tipped back (neck extended) so that his IOML is perpendicular to the IR. What degree of angulation of the central ray, and in which direction, would be required to successfully demonstrate the required structures? 37 degrees caudad Jeff Jefferson is on spinal immobilization precautions and requires a frontooccipital projection (Towne’s View) of his skull. His head is tipped back (neck extended) so that his OML is at a 10 degree angle to the IR. What degree of angulation of the central ray, and in which direction, would be required to successfully demonstrate the required structures? 40 degrees caudad Betty Smith is on spinal immobilization precautions and requires an AP projection (Reverse Caldwell) of her skull. Her head is tipped back so that her IOML forms a 4° angle with vertical. What degree of angulation of the central ray, and in which direction (if there is one), would be required to successfully demonstrate the required structures? 4 degrees cephalad What degree of angulation of the central ray, and in which direction, would be required to demonstrate the petrous ridges beneath the maxillary sinuses on an acanthioparietal projection (reverse Waters) of the facial bones if the patient’s neck is extended to place the OML at a 7 degree angle from perpendicular? (Hint: If the OML is perpendicular the tube angle will be 53 degrees). 46 degrees cephalad Bill Williamson is on spinal immobilization precautions and requires an AP open mouth projection of C1/C2. His neck is extended so that his occlusal plane forms a 5° angle with vertical. What degree of angulation, and in which direction, would be required to successfully demonstrate the required structures? 5 degrees caudad

To minimize distortion, how do you adjust the SID and OID? ↑SID and ↓OID True or False: If the radiographer is unable to achieve routine PA and Lateral images of a part, it is acceptable to perform two oblique views as long as the views are at 90° to each other. True. True or False: The more mobile the part to be imaged, the more adaptation will be required. False. True or False: Failure to document modifications may result in pathologies being missed or a misdiagnosis. True. True or False: A common site for fracture is adjacent to a prosthesis. True. True or False: It is never a good idea to explain procedures to an unconscious patient. False. True or False: It is not necessary for the radiographer to monitor the patient’s level of consciousness during the radiographic examination. False. True or False: It is possible to demonstrate an air/fluid level with a vertical central ray. False. Which level of trauma centre deals with the majority of trauma cases? Level 1. Which level of trauma center is typically rurual and able to stabilize the patient for transfer to another facility? Level 5. What is mechanism of injury? HOW the injury occurred. What is a distracting injury? One that is often so painful it masks the pain of a different injury. The following exams are ordered. Which order will you perform them in? AP chest, AP hip, PA hand, shoot-through lateral c-spine. C-spine, chest, hip, hand. What are 2 examples of a high-risk MOI? (Any 2 are fine). MVC, fall, assault...
