Patient positioning system and methods for diagnostic radiology and radiotherapy
First Claim
Patent Images
1. A patient positioning system for 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 pressure sensor attached to the patient immobilization device for sensing the patient; 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 indicative of a position within the patient immobilization device of the portion of the patient'"'"'s anatomy.

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.

18. A patient positioning system for alignment of a patient for radiation therapy and diagnostics (RTD) comprising:
- a head and/or neck immobilization device conformed to at least a portion of the head and neck region of the patient;
at least one sensor attached to the immobilization device(s) for sensing the patient; and
an external interrogator device, wherein said sensor(s) attached to the immobilization device(s) transmits data to said external interrogator device and said external interrogator device analyzes said data and provides a control output indicative of a position within the patient immobilization device of the portion of the head and a neck region of the patient. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
- a head and/or neck immobilization device conformed to at least a portion of the head and neck region of the patient;
-
28. A patient positioning system for alignment of a patient during medical treatment or diagnostics comprising:
- a surface for placing a portion of a patient'"'"'s anatomy thereon with a weight of the portion of the patient'"'"'s anatomy bearing on the surface;
at least one sensor attached to the surface for sensing the patient on the surface; and
an external interrogator device, wherein said at least one sensor transmits data to said external interrogator device and said external interrogator device analyzes said data and transmits a control output indicative of a position of the portion of the patient'"'"'s anatomy on the surface;
a memory for storing the control output from a plurality of patient positioning sessions and the interrogator unit further compares the control output from first and second patient positioning sessions and generates data indicative of the differences between the patient'"'"'s position during the first patient positioning session and the second patient positioning session.
- a surface for placing a portion of a patient'"'"'s anatomy thereon with a weight of the portion of the patient'"'"'s anatomy bearing on the surface;
