TECHNIQUES FOR COMPENSATING MOVEMENT OF A TREATMENT TARGET IN A PATIENT

Title:

TECHNIQUES FOR COMPENSATING MOVEMENT OF A TREATMENT TARGET IN A PATIENT

Document Type and Number:

WIPO Patent Application WO2006113323

Kind Code:

A3

Abstract:

Techniques for improving treatment delivered to a target site in a patient include delivering a treatment from a treatment delivery device to a target site in a patient supported by a patient support structure. During the delivery of treatment, a state of the patient is measured to produce real-time measurement data. Measuring the state is non-invasive; and the measured state is a correlated surrogate for position of the target site. Compensating movement data is determined based on the real-time measurement data to cause the target site to maintain a particular spatial relationship with the treatment delivery device. Either the treatment delivery device, or the support structure, or both, are moved based on the compensating movement data. When the delivery device alone is moved, the correlation between measured state and target site is based on partial least squares applied to pre-treatment measurements of both
