Abstract
A method and system for determining system-based tumor burden is disclosed. In one aspect, the method includes obtaining the medical image from a source, through an interface. Additionally, the method includes identifying a first region of interest in the medical image. The method also includes selecting from the first region of interest a second region of interest whose tumor burden is to be determined. Furthermore, the method includes defining a segmentation criterion for the second region of interest. The method also includes determining the tumor burden for the second region of interest.
Claims21
A method of determining a system-based tumor burden in a medical image, the method comprising:
- obtaining the medical image from a source through an interface;
- identifying a first region of interest in the medical image, wherein the first region of interest comprises one or more anatomical ranges of a body of a patient, the one or more anatomical ranges comprising a head and neck, a thorax, an abdomen, a pelvis, lower limbs of the patient, or a combination thereof;
- selecting from the first region of interest a second region of interest whose tumor burden is to be determined, wherein the second region of interest comprises at least one organ, at least one anatomical range, or a combination thereof from the first region of interest, and wherein the second region of interest is defined based on a physiological relationship and/or a pathophysiological relationship between organs, between anatomical ranges, between at least one organ and at least one anatomical range, or a combination thereof,
- defining a segmentation criterion for the second region of interest;
- and
- determining the tumor burden for the second region of interest.
A system for determining a total tumor burden in a medical image, the system comprising:
- a processing unit;
- a medical database coupled to the processing unit;
- a memory coupled to the processing unit, wherein the memory and processing unit are configured to:
- obtain the medical image from a source, through an interface;
- identify a first region of interest in the medical image, wherein the first region of interest comprises one or more anatomical ranges of a body of a patient, the one or more anatomical ranges comprising a head and neck, a thorax, an abdomen, a pelvis, lower limbs of the patient, or a combination thereof;
- select from the first region of interest a second region of interest whose tumor burden is to be determined, wherein the second region of interest comprises at least one organ, at least one anatomical range, or a combination thereof from the first region of interest, and wherein the second region of interest is defined based on a physiological relationship and/or a pathophysiological relationship between organs, between anatomical ranges, between at least one organ and at least one anatomical range, or a combination thereof;
- define a segmentation criterion for the second region of interest;
- and
- determine the tumor burden for the second region of interest.
A non-transitory computer-readable storage medium having machine-readable instructions stored therein, that when executed by a server, cause the server to:
- obtain a medical image from a source through an interface;
- identify a first region of interest in the medical image, wherein the first region of interest comprises one or more anatomical ranges of a body of a patient, the one or more anatomical ranges comprising a head and neck, a thorax, an abdomen, a pelvis, lower limbs of the patient, or a combination thereof;
- select from the first region of interest a second region of interest whose tumor burden is to be determined, wherein the second region of interest comprises at least one organ, at least one anatomical range, or a combination thereof from the first region of interest, and wherein the second region of interest is defined based on a physiological relationship and/or a pathophysiological relationship between organs, between anatomical ranges, between at least one organ and at least one anatomical range, or a combination thereof;
- define a segmentation criterion for the second region of interest;
- and
- determine the tumor burden for the second region of interest.
