Temperatures for Gantry and Detector

This document defines the available Real Time Statistics (RTS) data available on the system for the Gantry and Detector Temperature sensors. The RTS data is sent by the DCB to the host for the Detector temperatures and via the TGP for the gantry temperatures at the end of each exam.

The RTS viewer for the Gantry and Detector temperatures shows a listing of average, minimum and maximum temperatures seen during a specific exam. See Figure 1 for a pictorial view of the data to help in understanding the information seen. The information is grouped into 2 areas for the listed exam.

Gantry Temps

Below is a sample of the data seen with explanations and ranges defining normal operation.
