For low dose rate measurements
The RTI Dose Probe is an external dose probe, designed to perform very low dose rate measurements for instance on image identifiers.

To avoid or minimize interference with AEC (Automatic Exposure Control) on X-ray equipment, the probe is very small. This also enables it to fit into the table bucky. Since it is a solid-state detector, no corrections for pressure or temperature are needed. Neither is polarizing voltage.

Fluoroscopy

The RTI Dose Probe is small and has a fast response which makes it ideal for pulsed fluoroscopy. It can detect the individual pulses, determine pulse rate, and show waveforms at dose rate.

The RTI Dose Probe supports the ADI (automatic detector identification) system. When connected, the Piranha or Cobia automatically identifies the probe and makes all necessary adjustments without any need for interaction from the user. The RTI ADI system also gives full interchangeability of probes between different Piranha systems using the same type of probes.

With the extraordinary sensitivity of the Dose Probe, it is even suitable for scatter and leakage measurements.
