Surgery

Question 1

Radiography in surgery

Answer 1

• one of the most demanding
  challenges encountered by a
  radiologic technologist.
• To perform quickly and accurately in a
  sterile environment, with little repeat
  exposures

Question 2

Surgical Radiography
Imaging Equipment

Answer 2

• all imaging equipment should be in place and checked before the procedure has begun
• it must be cleaned and checked frequently
• once begun, there is no time to troubleshoot equipment

Question 3

A descriptive of a basic design of a mobile fluoroscopy unit, which forms a large C shape with the x-ray tube located at one end of the BLANK and the image intensifier tower at the other

Answer 3

C-arm

Question 4

In Mobile C-Arm Digital Fluoroscopy Systems what should the technologist be familiar with?

Answer 4

• C-arm, monitor, and image controls
• Various special beds or carts used with the C-arm

Question 5

O-arm imaging system

Answer 5

A mobile X-ray system designed for:
- 2D fluoroscopic
- 3D imaging
- Physicians benefit from 2D and 3D information on anatomic structures and objects with high X-ray attenuation such as bony anatomy and metallic objects

Question 6

Three cardinal rules of radiation protection

Answer 6

• time
• distance
• shielding

Question 7

Single-exposure capacity can greatly reduce fluoroscopy time

Answer 7

Intermittent Fluoroscopy

Question 8

Place the vertical alignment of the C-arm so the X-ray tube is away from the operator’s head and neck region. This is achieved by placing the X-ray tube beneath the OR table, thus reducing the dose to the head and neck region of the surgical team

Answer 8

DISTANCE - Vertical Alignment

Question 9

Benefits of minimize Distance Between Anatomy and Image Receptor

Answer 9

• brighter
• sharper
• a less magnified image
• reduction in radiation to the area

Question 10

SHIELDING

Answer 10

• Protective Lead Aprons
• Provide aprons for all personnel
• Wear a thyroid collar

Question 11

Answer 11

sterile and nonsterile areas

Question 12

sterile area includes

Answer 12

• patient
• surgical field
• surgeon
• surgical assistants
• surgical equipment
• tables
• carts

Question 13

nonsterile areas are the?

Answer 13

• technologist
• anesthesiologist
• circulator

Question 14

What is Draping of the C-Arm

Answer 14

Covering the C-arm with plastic or snap cover

Question 15

Image Receptors

Answer 15

• it must be placed in a sterile plastic cover
• The outer surface of the cover is sterile
• The inner surface of the cover is nonsterile and comes in contact with the IR
