Abstract

A method and related system (IPS) to support definition of a sub-volume (SV) in an initial image volume (IV).

First claim

The invention claimed is:

1. An image processing method, comprising:
receiving an image volume, a 2D profile shape, and a propagation curve, wherein said 2D profile shape and said propagation curve are directly provided by a user;
propagating said 2D profile shape across the image volume along said propagation curve to thereby generate a sub-volume in said volume, wherein said sub-volume encloses a pre-defined region of interest and a safety margin around the predefined region of interest;
monitoring said sub-volume during said propagation of said 2D profile shape along said propagation curve;
based on the monitoring, determining that said sub-volume does not properly enclose said pre-defined region of interest and said safety margin of said pre-defined region of interest;
in response to the determining:
automatically halting said propagating of said 2D profile shape across the image volume along said propagation curve;
causing an alert to be output by one or more output components of one or more computing devices;
receiving an additional propagation curve, wherein said additional propagation curve is distinct from said propagation curve; and
propagating said 2D profile shape across the image volume along said additional propagation curve to continue generating the sub-volume in said volume; and

displaying said sub-volume on a display device, wherein the image volume is stratified, wherein the propagation of said profile shape automatically terminates at an interface between two strata in the volume so that the sub-volume does not extend across said interface.

2. The image processing method of claim 1 , comprising displaying of said sub-volume together with the image volume.

3. The image processing method of claim 1 , comprising displaying the image volume, or at least a part thereof, and gradually building up display of the sub-volume during said 2D profile shape propagation whilst the sub-volume is being swept out in the image volume.

4. The image processing method of claim 1 , comprising:
computing a size of the sub-volume; or
computing a ratio between the sub-volume and the volume.

5. The image processing method of claim 4 , comprising:
issuing a first signal if the computed size of the sub-volume violates a first predefined threshold; or
issuing a second signal if the computed ratio violates a second pre-defined threshold, wherein the second pre-defined threshold is distinct from the first pre-defined threshold.

6. The image processing method of claim 1 , wherein the image volume is any one of an MM image, a CT image, an optical 3D image, a 3D ultrasound image, or a personalized or generic model.

7. The image processing method of claim 1 , wherein the 2D profile shape is adjustable.

8. The image processing method of claim 1 , wherein the 2D profile shape is automatically identified in the image volume.

9. An image processing system (IPS), comprising:
one or more processors; and
memory storing instructions, that when executed by one or more of the processors, cause one or more of the processors to:
receive an image volume, a 2D profile shape, a propagation curve wherein said 2D profile shape and said propagation curve are directly provided by a user;
propagate said 2D profile shape across the image volume along said propagation curve to thereby generate a sub-volume in said volume, wherein said sub-volume encloses a first portion of a pre-defined region of interest and a safety margin around the predefined region of interest;
monitor said sub-volume during said propagation of said 2D profile shape along said propagation curve;
based on the monitoring, determine that said sub-volume does not properly enclose said pre-defined region of interest and said safety margin of said pre-defined region of interest
in response to the determining:
automatically halt said propagating of said 2D profile shape across the image volume along said propagation curve;
cause an alert to be output by one or more output components of one or more computing devices;
receive an additional propagation curve, wherein said additional propagation curve is distinct from said propagation curve; and
propagate said 2D profile shape across the image volume along said additional propagation curve to continue generating the sub-volume in said volume; and

display said sub-volume on a display device, wherein the image volume is stratified, and wherein the propagation of said profile shape automatically terminates at an interface between two strata in the volume so that the sub-volume does not extend across said interface.

10. The image processing system of claim 9 , wherein the instructions further cause one or more of the processors to adjust the shape profile in response to a request.

11. The image processing system of claim 9 , wherein the instructions further cause one or more of the processors to automatically detect in the image volume the shape profile.

12. The image processing system of claim 9 , wherein the instructions further cause one or more of the processors to:
compute a size of the sub-volume; or
compute a ratio between the sub-volume and the volume.

13. A non-transitory computer readable storage medium storing computer instructions executable by a processor to perform a method comprising:
receiving an image volume, a 2D profile shape, and a propagation curve wherein said 2D profile shape and said propagation curve are directly provided by a user;
propagating said 2D profile shape across the image volume along said propagation curve to thereby generate a sub-volume in said volume, wherein said sub-volume encloses a pre-defined region of interest and a safety margin around the predetermined region of interest;
monitoring said sub-volume during said propagation of said 2D profile shape along said propagation curve;
based on the monitoring, determining that said sub-volume does not properly enclose said pre-defined region of interest and said safety margin of said pre-defined region of interest; and
in response to the determining:
automatically halting said propagating of said 2D profile shape across the image volume along said propagation curve;
receiving an additional propagation curve, wherein said additional propagation curve is distinct from said propagation curve; and
propagating said 2D profile shape across the image volume along said additional propagation curve to continue generating the sub-volume in said volume; and

displaying said sub-volume on a display device, wherein the image volume is stratified, and wherein the propagation of said 2D profile shape automatically terminates at an interface between two strata in the volume so that the sub-volume does not extend across said interface.
