9

***Operating Room Attire is

Proper attire include
–Protective eyewear
–Masks
–Shoe covers

–Caps
–Gloves
–ID & radiation badge

10

Operating Room Dance is

Maintaining sterile field
–Teams
–Certain rules
–Infection control
–Sterile field
•Communication

11

***Up to...........microbial particles can be shed from the skin per minute.

10,000

12

***What is a Draping of C-Arm

Plastic cover for C-arm

13

***Temporary draping is

–Plastic or cloth drape
–Remove

14

***What is “Shower curtain” method

Barrier between surgeon/patient and C-arm equipment

15

Principles of Aseptic Techniques

Radiographers should not walk between two sterile fields if at all possible.
Radiographers should avoid turning their backs toward the sterile field in compromised spaces.
Watch the front of clothing when it is necessary to be next to the patient.

16

When positioning an IR under the OR table, the radiographer should

Not lift the sterile drape above table level because this would compromise the sterile field

17

***Method when Surgical technologist (CST) taking IR

Sterile IR cover is held open by the CST
–Radiographer holds IR while placing into sterile cover
–CST will grasp IR and wrap cover securely

18

Method when Radiographer accepts IR after exposure:

Wear gloves to accept covered IR
•Blood/bodily fluids
–Grasp IR and open protective cover away from you and others so as not to spread any fluids
–Remove IR and dispose of IR cover in proper receptacle; remove gloves

19

***Mobile fluoroscopic units also called

C-arm

20

Function of Left monitor

Active or live

21

***Function of Right monitor

Hold or last/saved image

22

***Function of Cine loop

Images are recorded in rapid sequence and then displayed as a moving image (contrast injection)

23

Operational Modes includes

Mag or magnification mode
Pulse mode
Snapshot or digital spot mode
Film mode
Auto/Manual Exposure
Subtraction
Roadmapping
Boost
Foot Pedal

24

Pulse mode is

Pulsating beam at timed increments, reduces exposure

25

Film mode uses

Standard IR

26

Subtraction

Removes anatomy for better visualization

27

***Roadmapping

Creates live subtracted image (Contrast studies)

28

***Mini C-Arm used for

Extremity work (ER)
•Small and compact
•Limited dose & scatter radiation
–Lower energy levels

29

***Radiographer should stand @ a

Right angle (90 degrees) to the primary beam and the object being radiographed.
•The least amount of scatter radiation occurs @ this position.

30

***The greatest amount of scatter radiation occurs on the

Tube side of the fluoro machine

31

The x-ray tube SHOULD be placed

Under the patient

32

The x-ray tube should NEVER be placed

Above the patient unless absolutely necessary

33

***Tilting the C-arm significantly increases exposure to

The upper body and facial region not shielded by lead apron

34

***A tilt of 30° increases the dose by a factor of

4

35

Horizontal Projection: exposure region on the x-ray tube side of the patient is significantly greater than

The region near the intensifier tower
