## Abstract

Disclosed are systems, methods, and computer program products for tumor lesion identification, segmentation, tracking and analysis, wherein a 3D spatial distribution of the tumor lesions in a target organ forms a unique 3D point structure for a patient.

### Claim 4 (depends on 3)

The method of claim 3, wherein the clinical management decision comprises one of:
a disease is progressing rapidly and needs immediate intervention;
progression of the disease is slowing down so the disease is becoming stable;
a growth rate of lesions that have survived treatment is becoming faster, which is predictive of disease relapse; and
the disease is in regression.

### Claim 5 (depends on 2)

The method of claim 2, further comprising displaying a graphical user interface on a display, said graphical user interface comprised of at least four panels, said four panels including a user control panel, an information panel, and image display panel, and a lesion list panel.

### Claim 6

A system for tumor lesion identification, segmentation, tracking and analysis comprising:
an image capture device;
a memory; and
a processor in communication with the memory, wherein the processor executes computer-readable instructions stored in the memory that cause the processor to:
obtain a first set of one or more three-dimensional (3D) digital image that has been captured by the image capture device, wherein at least a portion of the one or more 3D digital images comprises a target organ;
segment the first set of one or more 3D digital images of the target organ into one or more first segment volumes of the target organ;
identify and segment a first set of one or more tumor lesions in each of the one or more first segment volumes of the target organ;
determine for each identified tumor lesion in the first set of one or more tumor lesions a three-dimensional location and a volume; and
create a 3D spatial distribution of the identified first set of tumor lesions, wherein the 3D spatial distribution forms a unique 3D point structure for a patient.
