Abstract

An oncology monitoring system comprises: an image analysis module (42, 44) configured to perform an oncological monitoring operation based on images of a subject, for example acquired by positron emission tomography (PET) and computed tomography (CT); and a clinical guideline support module (10). The clinical guideline support module is configured to: display a graphical flow diagram (GFD) of a clinical therapy protocol for treating the subject comprising graphical blocks (B0, B1, B2, B3, B4, B5, B21, B211, B22, B221, B222, B223, B23, B231, B232) representing therapeutic or monitoring operations of the clinical therapy protocol including at least one monitoring operation performed by the image analysis module; annotate a graphical block of the graphical flow diagram with subject-specific information pertaining to a therapeutic or monitoring operation represented by the graphical block; and display an annotation (POP) of a graphical block (B211) responsive to selection of the graphical block by a user.

First claim

Having thus described the preferred embodiments, the invention is now claimed to be:

1. An oncology monitoring system comprising:
an imaging controller configured to operate an imaging system to acquire medical images of a subject; a computer having a display, the computer configured to:
perform oncological monitoring operations that operate on the acquired medical images of a subject to analyze a cancerous tumor of the subject;
display, on the display of the computer, a graphical flow diagram of a chemotherapy, brachytherapy, or radiation therapy protocol for treating the subject, the graphical flow diagram comprising graphical blocks representing, the chemotherapy, brachytherapy, or radiation therapy protocol comprising a plurality of successive chemotherapy, brachytherapy, or radiation therapy sessions comprising a delivery of therapy followed by a recovery period, the graphical flow diagram including:
(i) therapeutic operations of the chemotherapy, brachytherapy, or radiation therapy protocol that are not performed by the computer and in which chemotherapy, brachytherapy, or radiation therapy treatment is delivered to the subject and
(ii) oncological monitoring operations of the chemotherapy, brachytherapy, or radiation therapy protocol that are performed by the computer on images of the subject,

annotate a graphical block of the graphical flow diagram representing an oncological monitoring operation with subject specific information pertaining to scan parameters used in performing the oncological monitoring operation represented by the graphical block and with a result generated by performing the oncological monitoring operation represented by the graphical block, the graphical flow diagram including (i) graphical blocks representing already completed therapeutic or oncological monitoring operations displayed using a first format and (ii) graphical blocks representing not yet completed therapeutic or oncological monitoring operations displayed using a second format that is visually distinguishable from the first format;
annotate a graphical block of the graphical flow diagram representing a therapeutic operation with subject specific information pertaining to administration to the subject of the therapeutic operation represented by the graphical block, the graphical block transitioning from the first format to the second format upon completion of the therapeutic operation;
display, on the display of the computer, an annotation of a graphical block responsive to selection of the graphical block by a user;
control the image controller to operate the imaging system to acquire medical images of the subject using the scan parameters annotated to the identified graphical block to generate a quantitative analysis of the cancerous tumor;
performing the next graphical block displayed in the second format using the acquired medical images;
store the annotated imaging assessment blocks in a database;
retrieve the annotated imaging assessment blocks for a subsequent imagine session of the subject to auto-populate the graphical flow diagram of the chemotherapy, brachytherapy, or radiation therapy protocol for the subject;
control the image controller to operate the imaging system to acquire medical images of the subject during the subsequent imaging session of the subject using the auto-populated graphical flow diagram;
annotate the graphical flow diagram with subject-specific information acquired from the medical images acquired during the subsequent imaging session; and
perform the next graphical block in the annotated graphical flow diagram.

2. The oncology monitoring system as set forth in claim 1 , wherein the computer is configured to annotate a graphical block of the graphical flow diagram with subject specific information received from a user pertaining to a therapeutic or oncological monitoring operation represented by the graphical block.

3. The oncology monitoring system as set forth in claim 1 , wherein the computer is configured to annotate a graphical block of the graphical flow diagram representing an oncological monitoring operation with quantitative results generated by the represented monitoring operation.

4. The oncology monitoring system as set forth in claim 1 , wherein the computer is configured to annotate a graphical block of the graphical flow diagram representing a therapeutic operation not performed by the computer with information pertaining to the therapeutic operation.

5. The oncology monitoring system as set forth in claim 4 , wherein the computer is configured to perform an oncological monitoring operation comprising performing quantitative analysis on images of the subject based at least in part on information pertaining to a therapeutic operation not performed by the computer, said information being received via an annotation to a graphical block representing the therapeutic operation.

6. The oncology monitoring system as set forth in claim 1 , wherein the computer is configured for operative connection with a positron emission tomography (PET) scanner and with a computed tomography (CT) scanner to control the PET scanner and the CT scanner to acquire the PET and CT images of the subject on which the computer performs oncological monitoring operation.

7. The oncology monitoring system as set forth in claim 1 , wherein the computer is further configured to:
perform guideline authoring via which a user constructs the graphical flow diagram of the chemotherapy, brachytherapy, or radiation therapy protocol.

8. The oncology monitoring system as set forth in claim 1 , wherein the computer is operatively connected with an imaging system to control the imaging system to acquire the images of the subject on which the computer performs oncological monitoring operations.

9. A method for monitoring a chemotherapy, brachytherapy, or radiation therapy protocol performed on a subject having a cancerous tumor, the method comprising:
using an imaging controller, operate an imaging system to acquire medical images of a subject;
using a computer, retrieving from a database a graphical flow diagram of the chemotherapy, brachytherapy, or radiation therapy protocol including imaging assessment blocks representing oncological monitoring operations performed on the acquired medical images and therapeutic operation blocks representing therapeutic chemotherapy, brachytherapy, or radiation therapy operations, the chemotherapy, brachytherapy, or radiation therapy operations comprising a plurality of successive chemotherapy, brachytherapy, or radiation therapy sessions comprising a delivery of therapy followed by a recovery period, the graphical flow diagram including (i) graphical blocks representing already completed therapeutic or oncological monitoring operations displayed using a first format and (ii) graphical blocks representing not yet completed therapeutic or oncological monitoring operations displayed using a second format that is visually distinguishable from the first format;
using the computer, annotating the graphical flow diagram with subject-specific information specific to the subject having the cancerous tumor;
using the computer, interfacing a user to navigate the graphical flow diagram with the annotated subject-specific information to identify a next imaging assessment block to be performed on the subject the graphical block transitioning from the first format to the second format upon completion of the therapeutic operation;
using the image controller, operate the imaging system to acquire medical images of the subject;
using the computer, performing the next graphical block displayed in the second format using the acquired medical images;
using the computer, annotating the identified imaging assessment
