Tumor Tracking System and Method for Radiotherapy

摘要

A system and method for tracking a tumor includes a regression module for selecting, using a motion signal and a regression function, a feature signal from a set of feature signals, each feature signal in the set of feature signals represents a medical image of the body of the patient, wherein the motion signal represents a motion of a surface of a skin of the patient caused by the respiration, and wherein the regression function is trained based on a set of observations of the motion signal synchronized with the set of feature signals; and a registration module for determining the location of the target object using the feature signal and a registration function, wherein the registration function registers each feature signal to a breath-hold location of the target object identified.

1. A system for facilitating an operation of a treatment delivery system based on a location of a target object in a body of a patient, wherein the location is subject to a motion caused by respiration of the patient, comprising:
a regression module for selecting, using a motion signal and a regression function, a feature signal from a set of feature signals, each feature signal in the set of feature signals represents a medical image of the body of the patient, wherein the motion signal represents a motion of a surface of a skin of the patient caused by the respiration, and wherein the regression function is trained based on a set of observations of the motion signal synchronized with the set of feature signals; a registration module for determining the location of the target object using the feature signal and a registration function, wherein the registration function registers each feature signal to a three-dimensional (3D) imaging data having a breath-hold location of the target object identified; and a control module for generating a command to facilitate the operation of the treatment delivery system based on the location.
