Abstract
Provided is a method and apparatus for tracking a tumor position, which changes by the movement of a body. According to various aspects, a location of a tumor position of a target organ may be estimated using images of one or more surrounding organs.
Claims15
A method of tracking a tumor position, the method comprising:
- generating a target organ model of a target organ having the tumor and a surrounding organ model of at least two surrounding organs located at the periphery of the target organ, based on a medical image comprising anatomical information of the target organ having the tumor and the at least two surrounding organs, by extracting unique anatomical characteristics of each organ, the unique anatomical characteristics of each organ comprising unique detailed anatomical structure of each organ;
- updating a shape, direction of movement, and a position of the at least two surrounding organs in the surrounding organ model based on the extracted unique anatomical characteristics of each organ and a dynamic image of the target organ and the at least two surrounding organs;
- updating the target organ model based on the updated surrounding organ model, wherein the updating of the target organ model comprises:
- determining a respiratory phase of a target body in the dynamic image based on the position of the at least two surrounding organs from the updated surrounding organ model;
- and
- updating a shape, direction of movement, and a position of the target organ model based on the determined respiratory phase, the extracted unique anatomical characteristics of each organ, and the dynamic image;
- estimating a position of the tumor included in the target organ based on the updated target organ model;
- and
- transmitting information regarding the estimated position of the tumor to a treatment apparatus,
- wherein the medical image has a first resolution and the dynamic image has a second resolution that is different than the first resolution.

An apparatus for tracking a tumor position, the apparatus comprising:
- one or more processors configured to:
- generate a target organ model of a target organ having the tumor and a surrounding organ model of at least two surrounding organs located at the periphery of the target organ, based on a medical image comprising anatomical information of the target organ having the tumor and at least two surrounding organs, by extracting unique anatomical characteristics of each organ, the unique anatomical characteristics of each organ comprising unique detailed anatomical structure of each organ;
- update a shape, direction of movement, and a position of the at least two surrounding organs in the surrounding organ model based on the extracted unique anatomical characteristics of each organ and a dynamic image of the target organ and the at least two target organs;
- update the target organ model based on the updated surrounding organ model, wherein to update the target organ model, the one or more processors is configured to:
- determine a respiratory phase of a target body in the dynamic image based on the position of the at least two surrounding organs from the updated surrounding organ model;
- and
- update a shape, direction of movement, and a position of the target organ model based on the determined respiratory phase, the extracted unique anatomical characteristics of each organ, and the dynamic image;
- estimate a position of the tumor included in the target organ based on the updated target organ model;
- and
- transmit information regarding the estimated position of the tumor to a treatment apparatus,
- wherein the medical image has a first resolution and the dynamic image has a second resolution that is different than the first resolution.
