Flashcards in Radiography Recall 1 Deck (37):
1

radiographic density

the more dense the tissue, the lighter it appears on xray

2

how do less dense tissues show up on xray?

darker

3

why do we measure for xrays?

because the thickness of the tissues determines how much xray needs to go through to make an image

4

how do you determine the risk of cancer from xray?

each exposure from each exam contributes to the lifetime radiation exposure of the patient

5

define radiographic positioning

the placement of the body or body part between the xray tube and the film or image receptor

6

CR

xray tube

7

IR

image receptor/film

8

What is the minimum amount of views you have to take?

2 opposing views

9

the two opposing views should preferably be how many degrees to each other?

90 degrees

10

define series in insurance terms

minimum amount of xrays for a complete exam

11

projection definition

the path of the xray beam as it enters and exits the body

12

view definition

the beam's perspective

13

position definition

the placement of the body or part

14

describe lateral position for xray

coronal plane is perpendicular to the IR

15

which side do you refer to when taking a lateral xray?

the side touching the IR

16

describe oblique position for xray

body or part is rotated from normal anatomic position

17

what do you refer to when you take an image of the trunk oblique?

the surfaces touching the IR

18

what do you refer to when you take an image of the extremity oblique?

internal or external rotation from normal anatomic position

19

what are the different body positions you can be in for xray while standing or seated?

PA or AP oblique (RAO, RPO, LAO, LPO) lateral (L or R)

20

what are the different body positions you can be in for xray while prone or supine?

PA or AP oblique (RAO, RPO, LAO, LPO) lateral (L or R) decubitus

21

axial view

there is more than a 10 degree tilt between the part and the CR (tube is usually tilted)

22

tangential view

the CR is directed so it intersects an object at only one point on the surface ("Skimming" the body part)

23

decubitus view

patient is recumbent, CR is horizontal, IR is vertical

24

when are air fluid levels demonstrated?

on upright and decubitus views only

25

what are the 3 basic rules for positioning?

1. the CR is centered to the middle of the part (and midfilm/IR) 2. the long axis of the part is parallel to the long axis of the IR 3. the CR is directed perpendicular to the part (and IR)

What is this called? When do we use it?

Q image thumb
