First Claim
Patent Images
1. A method for positioning a patient on a patient table during a radiation therapy or diagnostics (RTD) session comprising:
- positioning at least a portion of a patient'"'"'s anatomy relative to a patient immobilization device comprising at least one pressure sensor in a fixed position relative to said patient table;
obtaining real-time patient position data from said at least one pressure sensor;
monitoring patient position in real time with said patient position data to maintain said patient in a particular position for treatment or scanning prior to a RTD session, continuously during said RTD session, and/or in a subsequent RTD session.

Abstract
The system provides new ways to ensure that a patient is positioned correctly, e.g. identically with an original planning scan if the patient is to undergo radiotherapy. The system also detects if there is patient movement during a scan. It is an aspect of the present method to immobilize the patient based on a specific site of interest by using positioning sensors that record patient physical orientation based on measurements of patient weight distribution and pressure distribution among other features.
