CRS SCANNING SYSTEM

It is a building-block concept, meaning many of the components are interchangeable with each other and the computer software that drives them is common to all.

 

A PC-computer software controls the scanner mechanism and collects data in real time using an electrometer/controller as a remote interactive device.

 

The collected data is then later analyzed / plotted / printed / transferred to Treatment Plan files or other external non-CRS software.

Common MECHANICAL ACCURACY

Scan step size ¼ mm with user selectable scanning speed of up to 400 points/sec. (100mm/sec)

• Scanning positioning accuracy .25 mm
• Manual positioning accuracy +/- .1mm
• Reproducibility +/- .03mm

 

Hysteresis measured to be .5mm on X and Y profile scans.

Additional SOFTWARE PROCEDURES

Annual data, as well as other important depth/profile files, can be archived and recalled at a later date. Files no longer needed can be bulk erased to ease cluttering of a data folder.

 

TMR’s can be directly measured using a special lift table or alternate calculated from depth dose data. Profiles measured at SAD are also supported using the special lift table.
