Probes
|
vary based on the type of exam being done and the application needed
|
|
|
choosing your probe
|
depends mostly on imagine depth and desired resolution
|
|
|
higher probe megahertz (mHz)
|
the more superficial the imaging application
|
|
|
lower probe megahertz (mhz)
|
deeper imagine application
|
|
|
Curved array is usually used for
|
-abdominal
-renal -aorta/IVC -obstetric -gynocological |
|
|
Linear array is usually used for
|
-venous and arterial extremities
-thyroid -scrotum -carotids -breast |
|
|
Linear array mHz =
|
usually 5-10, some as high as 12-14
|
|
|
curved array mHz
|
usually 3-5
|
|
|
vector array mHz
|
the lowest at 1.5-3 mHz
Used for very deep imaging, between the ribs or through bony structures. |
|
|
vector array is used for
|
-transcranial doppler
-cardiac imaging -abdominal structures through large habits -between ribs or bony structures in abdomen/thorax |
|
|
gain
|
adjusts the brightness of the entire image
|
|
|
turning up gain
|
makes entire image brighter
|
|
|
turning down gain
|
makes entire image darker
|
|
|
TCG
|
allows you to adjust for one area of imagine being too dark or light without adjusting entire image
|
|
|
When starting an exam, TCG should be
|
straight up and down
|
|
|
imagine depth is dependent upon
|
the patient and the structure to be imaged.
|
|
|
increasing your depth
|
imaging deeper
|
|
|
decreasing your depth
|
imaging more superficially
|
|
|
focal zone
|
helps machine determine where the important part of the image is
|
|
|
freeze
|
-freezes the image
-always freeze before you capture |
|
|
capture
|
stores image on machines hard drive
|
|
What needs to be adjusted on this image?
