Discussed herein are devices, systems, and methods for organ mask generation. A device, system and method for organ mask generation including generating a synthetic centroid mask, identifying first and second intensity thresholds, in a first segmentation pass, setting (i) pixels of an image with intensities less than the first threshold to zero and (ii) pixels of the image corresponding to objects with centroids outside the synthetic centroid mask to zero, resulting an initial organ mask, in a second segmentation pass, setting pixels (i) with intensities less than the second threshold, the second threshold less than the first threshold to zero and (ii) setting pixels corresponding to objects with centroids outside the initial organ mask to zero, resulting in a second organ mask, and expanding and filling the second organ mask to generate an organ mask.

Organ segmentation in image

A system and method for generating and displaying contours. In some embodiments, the method includes: calculating a first threshold, based on a first target point in a first slice; and generating a first contour, the first contour being a boundary of a first region, the first region being a region within which: the elements of the first slice are greater than the first threshold, or the elements of the first slice are less than the first threshold.

System and method for generating and displaying contours

A system and method for generating and displaying contours. In some embodiments, the method includes: generating a respective first axial contour, of a plurality of first axial contours, for each of a first plurality of axial slices, the first axial contours defining a surface of a first volume, a first axial slice of the first plurality of axial slices including a first target point; generating a first sagittal contour in a first sagittal slice through the first target point; generating a respective second axial contour, of a plurality of second axial contours, for each of a second plurality of axial slices including the first axial slice, the second axial contours defining a surface of a second volume, a first slice of the first plurality of axial slices including a second target point; and generating a second sagittal contour in the first sagittal slice.

A method for analyzing scan data. In some embodiments, the method includes forming, from a first scan data array, a first mask, each element of the first mask being one or zero according to whether the corresponding element of the first scan data array exceeds a first threshold; forming, from the first scan data array, a second mask, each element of the second mask having a value of one or zero according to whether the corresponding element of the first scan data array exceeds a second threshold, the second threshold being less than the first threshold; and forming a fourth mask, the fourth mask being the element-wise product of the second mask and a third mask, the third mask being based on the first mask.

Organ isolation in scan data

A system and method for generating contours in medical imaging scans. In some embodiments, the method includes calculating a first threshold, based on a first target point in a normalized scan data array, and generating a first contour. The contour may be a boundary of a first region, the first region being a region within which the elements of the normalized scan data array are less than the first threshold.

System and method for generating contours

A system and method for detecting tumors. Three-dimensional scans of a patient are performed with penetrating radiation, before and/or after the injection of a contrast agent. Raw density arrays are formed from the scans. The median density within an organ is calculated and subtracted from each of the raw density arrays, to form offset arrays. The offset arrays are subtracted pairwise and the differences are summed to form a discriminator array.
