RTI T20 Dose Probe

Use anywhere in the X-ray field

 

The RTI T20 Dose Probe is a solid-state detector dedicated to measurements on Rad/Fluoro systems when it is crucial that the detector itself does not have any effect on the system output or disturb the X-ray beam.

It was developed for measurements of the patient entrance dose (skin dose) and the maximum dose rate in the radiographic and fluoroscopic field. Despite its small size, the RTI T20 Dose Detector is protected from picking up backscatter.

Place it anywhere!

The RTI T20 Dose Probe can be placed anywhere in the X-ray field in contrast to many other detectors. The RTI Dose Probe, for instance, is small but not small enough in all situations. It still has to be placed outside the active area to avoid affecting the feedback of the system.

 

Independent and sensitive

The RTI T20 can connect to either Piranha, Cobia FLEX, or Cobia SENSE, and has a built-in correction filter that allows the detector to self-compensate for different beam energies. Therefore it has a flat energy response in the radiographic range with no need for correction factors. The RTI dose detector gives about five times higher sensitivity than a typical ion chamber.
