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
