ITEM
DESCRIPTION
Check data when these functions are not active.
Background Count
In Dynamic Pitch Mode: a baseline value in counts per second stored in console and used as
threshold to activate sound
In Binary Pitch Mode: baseline value in counts per second stored in console for comparison to
Target Count determines if difference in radioactivity between Background Tissue and Target
Tissue is statistically significant.
Compton Scattering
Radioactive noise at an energy level lower than photo peak of radioactive material.
Ratio Readout
A value indicating how likely it is that Target Tissue is identified (Target Count divided by
Background Count).
Dynamic Pitch
Default mode of operation: baseline value measured in counts per second that is stored in console,
and used as threshold at which sound is activated.
Binary Pitch
Optional mode of operation: baseline value measured in counts per second that is stored in console
for comparison to Target Count determines if difference in radioactivity between Background
Tissue and Target Tissue is statistically significant.
Scan/Scanning
Moving probe across Target Area to locate highest radiation reading.
Target Area
Area of interest selected by physician during a procedure
Target Check
Binary Pitch Mode Only: quick check of level of radioactivity measured in counts per second
detected by a probe held stationary for 2 seconds over target tissue; more accurate than Count
Rate. Target Check function does not display a calculated Ratio Readout.
Target Count
Number indicating level of radioactivity detected by probe when held stationary for 6 seconds
over Target Tissue; more accurate than Target Check. Target Count activates and displays a
calculated Ratio Readout; 6 seconds in Binary Pitch mode; 1 to 6 seconds in Dynamic Pitch mode.
Caution: United States Federal Law restricts this device to sale by or on order of a physician.
