44
Q

Name the directional planes in order

A

Saggittal/Longituidnal

Transverse/axial

coronal/frontal

45
Q

When you measure anterior to posterior, what are you measuring?

A

height

46
Q

What is echoegenic?

A

the ability to return sound waves/producing sound waves

ex) organs/ tissues

47
Q

what is isoechoic?

A

when structures have the same relative echo density

48
Q

what is hyperechoic?

A

brighter than normal or brighter than adjacent structures

49
Q

what is hypoechoic?

A

not as bright as normal or less bright than adjactent structures

50
Q

anechoic

A

no echoes, black

ex) IVC, AO

51
Q

homogeneous

A

even and uniform echo pattern

52
Q

heterogeneous

A

uneven echo pattern with varying echodensities

53
Q

DMS frequency range is btw

A

2-15MHz

54
Q

Explain why we use low frequencies for deep penetration and high frequencies for superficial penetration

A

•Higher frequencies have shorter wavelengths & are absorbed/attenuated more easily. Therefore, higher frequencies are not as penetrating. This explains why high frequencies are used for the superficial body structures and low frequencies are used for those that are deeper.

55
Q

1 Hertz =

A

1 wave per second

56
Q

frequency range for deep abdomen or OB/GYN scanning

A

2.0-2.5 MHz

57
Q

frequency range for general abdominal/ OB/GYN imaging

A

3.0-3.5 MHz

58
Q

frequency range for vascular, breast, and pelvic imaging

A

5 MHz

59
Q

frequency range for breast/thyroid imaging

A

7.5 MHz

60
Q

frequency range for Breast, thyroid, superficial veins/masses, MSK imaging

A

10 MHz

61
Q

frequency for superficial structures and MSK imaging

A

15 MHz

62
Q

Is the liver heterogeneous or homoegeneous image?

Is the AO anaechoic or isoechoic?

A

homogeneous- even and uniform

anaechoic- all black

63
Q

This image is an example of ___.

A

heterogenous echo pattern- uneven with varying echodensities

64
Q

What is wrong with this image?

A

too little overall gain

65
Q

What is wrong with this image?

A

too much overall gain

66
Q

How could this image be fixed?

A

adjust the TGCs to be uniform with the rest of the image

67
Q

What is wrong with the image?

A

Image is good, no adjustments needed
