Systems and methods for generating projection images
First Claim
Patent Images
1. A method of forming an image of an object, comprising:
- receiving, using at least one processing unit, a three-dimensional array of voxels representing an object;
selecting, using the at least one processing unit, a subset of voxels from the array representing a region of interest (ROI) of the object, the subset of voxels representing one or more portions of a plurality of image slices of the object, the subset of voxels selected along a direction perpendicular to a view direction defined by the region of interest; and
forming an image of the ROI by processing the subset of voxels to at least sum data of the object included in the subset of voxels along the view direction.

Abstract
Systems, methods, and non-transitory computer-readable media taught herein process a subset of a three-dimensional array of voxels to form an image of a region of interest in an object. Images thus formed are clear, comprehensible, and contextual. The systems, methods, and non-transitory computer-readable media taught herein select the subset of voxels that represent the region of interest along a direction perpendicular to a view direction defined by the region of interest. The subset of voxels represents one or more portions of a plurality of image slices of the object.

29. An imaging system, comprising:
-
an imaging apparatus to acquire measurement data of an object; and a programmable processing unit having a central processing unit, communicatively coupled to a memory, wherein upon execution of processor-executable instructions, the programmable processing unit operates to; receive a three-dimensional array of voxels representing the object; select a subset of voxels from the array representing a region of interest (ROI) of the object, the subset of voxels representing a subset of one or more portions of a plurality of image slices of the object, the subset of voxels selected along a direction perpendicular to a view direction defined by the ROI; and form an image of the ROI by processing the subset of voxels to at least sum data of the object included in the subset of voxels along the view direction. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59)

60. A computer-implemented method comprising:
-
rendering, on a display, a graphical user interface (GUI) window to display an image of an object; receiving, via one or more graphical user interface elements of the GUI, an identification of a region of interest in the object; in response to the identification of the region of interest, processing a subset of voxels from a three-dimensional array of voxels representing the object to form an image of the ROI by at least summing data of the object included in the subset of voxels along the view direction, the subset of voxels representing one or more portions of a plurality of image slices of the object, the subset of voxels selected along a direction perpendicular to a view direction defined by the region of interest; rendering the image of the ROI in the GUI window; and receiving input via the GUI to manipulate the image of the ROI. - View Dependent Claims (61, 62, 63, 64, 65, 66)
