First Claim
1. A computer system for segmenting a medical image, the system comprising:
- at least one processor and a memory having stored thereon instructions that, upon execution, cause the system to perform functions comprising;
inputting the medical image into at least a first segmentation method;
deriving at least one set of probabilities of belonging to at least one tissue class for each pixel of a medical image using the at least a first segmentation method;
inputting the medical image into a final neural network;
inputting the at least one set of probabilities into the final neural network; and
segmenting the medical image into the at least one tissue class based on the medical image and the at least one set of probabilities by the final neural network.

Abstract
Methods and systems for segmenting a medical image into classes are described. A system to segment a medical image includes a processor and memory with instructions that upon execution cause the system to perform a method for segmenting the image. The method includes using initial segmentation methods to derive at least one set of probabilities of belonging to the classes for each pixel of the image. The at least one set of probabilities and the image are input into a neural network which segments the image based on both the probabilities and the image provided. This system can also use patches or sub-sections of the original image and the at least one set of probabilities as inputs to the final neural network. The patch based method enables segmentation of larger images, which usually require large amounts of time and memory to segment, and can produce a highly trained neural network.
