Ultrasound Machine Flashcards
where radiation comes from
source
source of radiation in ultrasound
probes
each probe has different purpose.
TF
True
before doing the probes, we need to apply the what
transducer gel
its purpose is to reduce friction in probese
transducer gel or acoustic gel
transducer gel is usually warm
TF
false it is cold
procedure for ultrasound
- know the procedure
- remove any obstructions
- transducer to reduce friction and clear image
it comes from the word gonad, meaning reproductive system
gonadal shielding
this shielding is useed for btoh males and femalees
gonadal shielding
shields not only the gonads, but also other sensitive organs such as the spleen
lead apron
the purpose of these is to reduce the radiation interaction of our bodies. however, it does not entirely protect us
shield
where the viewbox is. this is where you can see the images
negatoscope
this is where you view images after processing
negatoscope
if its dark you cannot see anything in the negatoscope.
TF
true
do not leave patients in wheelchair unattended, even more when it is unlocked.
wheelchair
in terms of transfer, how should a wheel chair be moved.
parallel
this is where we manipulate technical factors
control console
this is where we shoot xrays
control console
the purpose of the window or lead glass in control console is to reduce what
radiation interaction for the controller of the console
parts of portable x-ray machine
switch
x-ray tube
beam restrictor
types of xray switch
half and full switch
this is what we use when we expose radiation
switch
it is used to gather x-ray energy
half push or half switch
it is used to exppose the patient to the x-ray. to balls the patient with x ray
full push/ fulll switch
this is where x ray goes out of
x ray tube
the light that we see in x ray
beam restrictor
how does the light changes in x ray depending on the need of the patient
smaller or bigger
it is the device designed to control and minimize scatter radiation by limiting the x-ray field size to only the anatomy of interest.
beam resetrictor
there needs to be allowance for the x ray beam for what
to avoid shortage of image that will result in repeat exposure.
x ray procedure for patients
- know the procedure
- remove obstructions
- move the arms to the side.
different kinds of position of the patient, different body parts to be evaluated
positioning chart
each projection or procedure has its own purpose. it depends on what we need to evaluate
positioning chart
this is where we put the film cassette
vertical cassette holder (vchs)
image receptor
receivere of radiation
inside of this is a film
cassette
each cassette has different purpose: enumerate
10x12 - head
14x14 - chest
14x17 - pelvis, thigh (longest so diagonal)
17x17 - biggest
cassette ideal for head
10x12
cassette for chest
14x14
cassette for pelvis and thigh
14x17
biggest cassette
17x17
this part of x ray is very sensitive to light
film
to manipulate the flow of electricity so it won’t overload
transformer
dark room procedure in developing film
1 - wet film with water
2 - dip the film to the developer solution
3 - wet the film with water
4 - dip the film to the fixer solution (vinegar)
5 - wet the film with water
6 - dry
different chemicals have their own different purposes for making the images visible
true
make sure all white light is not present before reloading the film
true
pwede red light pero make sure na di siya maeexpose ng matagal
true
red has the lowest energy output of all the colors with violet being the strongest
truee
if the film is exposed to light, the image will result as dark or overexposed.
true
no white light should be present when film laoding
true
is there a maximum time in film loading?
no
all films are sensitive to light, and those that are not sensitive are digital based cassette/receptors
true
this is where you put the name of patient in xray
