1

Diagnostic yield

Amount of clinically useful information on a diagnostic image. Must outweigh the input factors of the procedure ordered. (Is the correct test being ordered?)

2

Competent imaging professionals will strive to maximize diagnostic yield using a minimum of _________ factors.

input

3

Diagnostic efficacy

Accuracy of diagnostic information on a medical image. (Did the test provide the information that was needed?)

4

Any extraneous information on an image that does not reflect the patient's true medical condition _________ from diagnostic efficacy

detracts

5

What is included in the X-Ray Machine Design Features?

X-ray tube and x-ray tube support Collimator assembly Radiographic table X-ray generator and control Upright image receptor

6

Tube is inside the lead-lined tube housing. The X-Ray tube is made of ________ glass with high vacuum. The tube produces x-radiation when high-energy electricity passes through. Then X-radiation exits the tube through a window in the housing and is directed toward a patient.

Pyrex

7

The ___________ _______________ Projects a high-intensity light field on the patient, which represents the area of the x-ray field exposure.

Collimator Assembly

8

Collimation May be manual or automatic (PBL). What does PBL stand for?

Positive beam limitation

9

The radiographic Tabletop is highly ______________.

radiolucent

10

Tilting radiographic tables will tilt from __________ to __________ to __________. These tables typically do not have variable _________ capabilities.(used in fluroscopy)

Horizontal Vertical upright Trendelenburg Height

11

Within the tabletop, radiographic grid oscillates during exposure to blur out the ________ ________ ________.

lead grid lines

12

The interface between the radiographer and electronics of the x-ray machine

Control console

13

Three key factors for exposure technique.

kVp mA Time

14

Facilitate easy and efficient positioning of the x-ray tube assembly around the patient in any orientation.

X-Ray Tube Supports

15

Overhead Tubecrane (OTC) motions.

Longitudinally Vertically Transversely

16

Receives remnant radiation from patient and captures the x-ray energy for processing.

Image Receptor

17

Image Receptor technology is classified as __________ or __________.

Cassette-based (CR) Cassette-less (DR)

18

Cassette-based receptor systems.

Film-screen Computed radiography (CR)

19

Systems that use thin-film technology (TFTs).

DR systems (Referred to as flat panel technology)

20

Only radiation that is of any clinical value.

Radiation absorbed by detector Radiation able to be converted to an image

21

Converts x-ray to light before converting it to an electrical signal.

Indirect digital detector technology Photostimulable Phosphor (PSP) storage-phosphor technology computed radiography (CR)

22

CR plates are extra sensitive to ______ energy radiation after they have been exposed.

low

23

Technology that converts an x-ray into an electrical signal.

Direct digital detector technology

24

________ technology has improved spatial resolution and lower patient dose. It is more dose efficient.

DR

25

Provides live, real-time images of patients using x-rays.

Fluoroscopy

26

Fluoroscopy performed in surgery is typically accomplished with __________.

Portable C-arm system

27

Commonly referred to as a "portable"

Mobile X-Ray Imaging
