Q

what are the different transducer movements? explain.

A

tilting - angling/fanning like a broom
rocking - aka heel/toe - like a rocking chair
sliding - physically move across body surface
rotate - turn clockwise or counterclockwise/ pivot
compress - push down more on body

16
Q

explain the orientation of the screen in sagittal

A

top - anterior aspect - skin
bottom - posterior aspect
my left on screen - superior (head)
my right on screen - inferior (feet)

17
Q

explain the orientation of the screen in transverse

A

top - anterior aspect - skin
bottom - posterior aspect
my left on screen - right side of body
my right on screen - left side of body

18
Q

anechoic

A

no/lack of echos - black

19
Q

hypoechoic

A

fewer echos - darker

20
Q

hyperechoic

A

increased density of echos - brighter

21
Q

isoechoic

A

same echogenicity as structure next to it - appear similar

22
Q

echogenic

A

the ability to transmit echos - increased echos

23
Q

heterogenous

A

mixture of echo’s in a structure
differing composition

24
Q

homogenous

A

all echo’s are same level/shade
uniform/similar composition

25
Q

complex

A

mixture of echogenicity’s
consists of both solid and cystic components

26
Q

acoustic shadowing

A

area through which sound waves fail to propagate
a single void behind structures that strongly absorb or reflect u/s
- happens in solid structures - b/c molecules compact

27
Q

acoustic enhancement

A

increased echos deep to structures that transmit sound well.
lack of attenuation
fluid filled structures

28
Q

what are the regions of the abdomen?

A

R/L hypochondriac
Epigastric
R/L lumbar
umbilical
R/L inguinal/iliac
hypogastric

29
Q

In what order would one adjust the machine controls?

A

depth, focus, gain, TGC

30
Q

what is depth?

A

how much of the structure is seen - how deep our waves go into the patient - set 2cm below structure

31
Q

what is focus?

A

the sharpest part of your image - aim to back of structure - clears up image

32
Q

what is gain?

A

overall brightness of the image. use to amplify echos and see texture

33
Q

what is TGC? `

A

used to amplify echos in sectors of the image
