Abstract

A stand-alone platform and a method for the multi-dimensional rendering, display, manipulation, and analysis of full high resolution volumetric data sets. The systems and methods provide the ability to volumetrically render images with extremely high resolution in applications such as medical imaging procedures, digital microscopy such as in use of a confocal microscope, and other areas where extremely large data sets are produced from the imaging process. Certain embodiments of the system and methods produce left and right eye images of the rendered data, for viewing in parallax via a synchronized headset, and the ability to manipulate the data and display of image data easily and in real time.

Claims

a platform to render a plurality of fully acquired volumetric data sets received from a plurality of volumetric data sources, the plurality of fully acquired volumetric data sets including data related to at least a single volume and at least one set of fully acquired volumetric data received in real time;

a graphics processor to import said plurality of fully acquired volumetric data sets to a common coordinate space, and co-registering of the plurality of fully acquired volumetric data sets temporally with respect to each other such that the plurality of fully acquired volumetric data sets are properly temporally represented with respect to one another; and

wherein co-registering the plurality of fully acquired volumetric data sets is performed without an interpolation process,

at least one display system operationally connected to said platform to display said plurality of fully acquired volumetric data sets.

2. The system of claim 1, further comprising at least one human interface device (HID) operationally connected to said platform to provide interactive manipulation and modification of at least one of said plurality of fully acquired volumetric data sets in real time.

3. The system of claim 2, wherein said at least one human interface device (HID) enables a user to select at least one of a predetermined time and predetermined interval of said rendered volumetric image data.

4. The system of claim 3, wherein said at least one human interface device (HID) enables interactive quantitative analysis of said displayed rendered fully acquired volumetric image data.

The system of claim 2, wherein said at least one human interface device (HID) further comprises stereoscopic eyewear selected from the group consisting of an active stereoscopic eyewear connected to and synchronized with at least one stereoscopic display subsystem and adapted to provide active stereoscopic viewing of said displayed rendered volumetric image data in real time to a user wearing said active stereoscopic eyewear or a passive stereoscopic eyewear adapted to provide passive stereoscopic viewing of said displayed rendered fully acquired volumetric image data in real time to a user wearing said passive stereoscopic eyewear.

6. The system of claim 1, wherein said system to co-register the plurality of fully acquired volumetric data sets operates to register the fully acquired volumetric data sets to a common spatial coordinate system automatically or semi-automatically.

7. The system of claim 1, wherein said system to co-register the plurality of fully acquired volumetric data sets operates to preprocess the fully acquired volumetric data sets.

8. The method system of claim 1, further comprising at least one human interface device (HID), wherein said HID provides interactive quantitative analysis of said displayed rendered volume image from the plurality of fully acquired volumetric data sets.

9. The system of claim 1, further comprising a hardware portion of said graphics processor and a software portion of said graphics processor.
