First Claim
Patent Images
1. A patient positioning system for precise, accurate and stable alignment of a patient during radiation therapy and diagnostics (RTD) comprising:
- a patient immobilization device conformed to at least a portion of a patient'"'"'s anatomy;
at least one sensor attached to the patient immobilization device; and
an external interrogator device, wherein said immobilization device transmits data to said external interrogator device and said external interrogator device analyzes said data and transmits a control output.

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.

19. A method for precise, accurate and stable positioning of a patient during radiation therapy and diagnostics (RTD) comprising:
- conforming a patient immobilization device comprising at least one sensor to a portion of a patient'"'"'s anatomy identified for treatment;
connecting said at least one sensor to an external interrogator device;
interrogating the sensor for a patient position pattern and receiving the patient position pattern by an external interrogator device in real-time;
evaluating said patient position pattern by said external interrogator device to determine a treatment position;
monitoring said treatment position in real-time;
maintaining said treatment position continuously prior to, in the course of and/or subsequent to radiotherapy; and
delivering radiotherapy to the tumor and/or body region of interest. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
