Abstract

Mechanisms for image processing are provided. A computing device comprises a memory, an input device, a display, and a processor. The processor is configured to: acquire a three-dimensional image of an anatomical structure and store it in the memory. The processor renders on the display (i) an initial volume of the three-dimensional image corresponding to an initial portion of the anatomical structure, and (ii) a moveable control element. The initial volume has an outer surface defined by a position of the control element. The processor receives input data updating the position of the control element relative to the initial volume; and renders on the display, in place of the initial volume, a further volume of the three-dimensional image, corresponding to a further portion of the anatomical structure and having a further outer surface defined by the updated position of the control element.

First claim

We claim:

1. A computing device comprising:
a memory;
an input device;
a display; and
a processor interconnected with the memory, the input device and the display, the processor configured to:
acquire a three-dimensional image of a brain and a skull of a patient and store the three-dimensional image in the memory;
obtain a boundary surface between the brain and the skull;
render on the display (i) an initial volume of the three-dimensional image corresponding to the brain, excluding the skull, by clipping the three-dimensional image at the boundary surface, and (ii) a mask depth control element movable to adjust a clipping mask, the clipping mask having an initial position corresponding to the boundary surface;

acquire an additional image of fluid flow tracts within the brain of the patient;
render, on the display, an additional volume of the additional image overlaid with the initial volume, the additional volume having an outer surface that is independent of the position of the mask depth control element;
receive, from the input device, input data updating the position of the mask depth control element of the display relative to the initial position corresponding to the boundary surface;
responsive to receiving the input data;
set a position of the clipping mask according to the boundary surface modified by the updated position of the mask depth control element;
select a further volume of the three-dimensional image by clipping the three-dimensional image at a clipping mask, and
render on the display, in place of the initial volume, the further volume of the three-dimensional image.

2. The computing device of claim 1 , wherein the three-dimensional image is a magnetic resonance imaging (MRI) scan.

3. The computing device of claim 1 , wherein the processor is further configured to render on the display an additional volume corresponding to a tumor; the additional volume having an outer surface that is independent of the position of the control element.

4. A method of processing images in a computing device having a memory, an input device, a display and a processor interconnected with the memory, the input device and the display, the method comprising:
acquiring a three-dimensional image of a brain and a skull of a patient and storing the three-dimensional image in the memory;
obtaining a boundary surface between the brain and the skull;
at the processor, rendering on the display (i) an initial volume of the three-dimensional image corresponding to the brain, excluding the skull, by clipping the three-dimensional image at the boundary surface, and a mask depth control element movable to adjust a clipping mask, the clipping mask having an initial position corresponding to the boundary surface;
acquiring an additional image of fluid flow tracts within the brain of the patient;
rendering, on the display, an additional volume of the additional image overlaid with the initial volume, the additional volume having an outer surface that is independent of the position of the mask depth control element;
receiving, at the processor from the input device, input data updating the position of the mask depth control element on the display relative to the initial position corresponding to the boundary surface;
responsive to receiving the input data;
setting a position of the clipping mask according to the boundary surface modified by the updated position of the mask depth control element,
selecting a further volume of the three-dimensional image by clipping the three-dimensional image at the clipping mask; and
controlling the display at the processor to render, in place of the initial volume, a further volume of the three-dimensional image.

5. The method of claim 4 , wherein the three-dimensional image is a magnetic resonance imaging (MRI) scan.

6. The method of claim 4 ; further comprising rendering on the display an additional volume corresponding to a tumor, the additional volume having an outer surface that is independent of the position of the control element.
