Dynamic/adaptive treatment planning for radiation therapy
First Claim
1. A method in a computing system for facilitating custom radiation treatment planning, comprising:
- during a first radiation treatment session associated with a first treatment plandeterming locations of a plurality of markers implanted in a patient'"'"'s body using non-ionizing radiation, andcollecting data indicating positioning of a predefined treatment site of the patient relative to a target treatment location based on the determined locations throughout the first radiation treatment session;
associating the collected positioning data with data describing a plurality of radiation treatment fields used during the first radiation treatment session;
providing at least the associated data to a treatment planning facility to determine a second treatment plan for a future radiation treatment session for the patient to be performed on a different date than the first treatment plan and over a period of time; and
producing the second treatment plan bycomparing intended positioning data of the first treatment plan with the collected positioning data throughout the first radition treatment session, andmodifying the first treatment plan based on the comparison of the intended positioning data with the collected positioning data.

Abstract
A facility for facilitating custom radiation treatment planning is described. During a distinguished radiation treatment session for a patient, the facility collects data indicating positioning of a predefined treatment site of the patient relative to a target treatment location throughout the distinguished radiation treatment session. The facility associates the collected positioning data with data describing one or more other aspects of the distinguished radiation treatment session. The facility provides the associated data to a treatment planning facility to determine a treatment plan for future radiation treatment sessions for the patient.

14. A method in a computing system for facilitating custom radiation treatment planning using a plurality of markers implanted in a patient'"'"'s body proximate a target treatment location, the method comprising:
-
during a first radiation treatment session for a patient, determing locations of the markers using non-ionizing radiation and collecting data indicating positioning of a predefined treatment site of the patient relative to the target treatment location throughout the first radition treatment session, wherein the first radiation treatment session is associated with a first treatment plan that includes data indicating intended positioning through the first radiation treatment session of the predefined treatment site of the patient relative to the target treatment location; associating the collected positioning data with data describing a plurality of radiation treatment fields used during the first radiation treatment session; comparing intended positioning data of the first treatment plan with the collected positioning data throughout the first radiation treatment session; and providing at least the associated data to a treatment planning processor to determine a second treatment plan for a future radiation treatment session for the patient to be performed on a different date than the first treatment plan, wherein the second treatment plan is a modification of the first treatment plan based at least in part on the comparison of the collected positioning data with the intended positioning throughout the first radiation treatment session. - View Dependent Claims (15, 16, 17, 18)

19. A system for facilitating custom radiation treatment planning using a plurality of markers implanted in a patient'"'"'s body proximate a target treatment location, the system comprising:
-
a first subsystem configured to determine locations of each of the markers during a first radiation treatment session using non-ionizing radiation, collect data indicating a position of a predefined treatment site relative to the target treatment location based on the determined locations throughout the first radiation treatment session; associate the collected positioning data with data describing a plurality of radiation treatment fields used during the first radiation treatment session; and provide at least the associated data to a second subsystem, wherein the second subsystem is configured to determine a second treatment plan for a future radiation treatment session for the patient to be performed on a different date than the first treatment plan, and wherein the second treatment plan is a modification of the first treatment plan based at least in part on a comparison of the collected positioning data with the intended positioning throughout the first radiation treatment session. - View Dependent Claims (20)
