A method for automatic segmentation of a medical image is provided. The method comprises registering a reference image associated with an object to the medical image, determining a transformation function on the basis of the registration, applying the transformation function to a probability map associated with the object; carrying out a probability thresholding on the transformed probability map by selecting a first area of the medical image in which the probability of the object is within a probability range, carrying out an intensity thresholding on the medical image by selecting a second area of the medical image in which the intensity is within an intensity range, selecting a common part of the first and second areas and carrying out on the common part a morphological opening resulting in separate sub-areas, selecting the largest sub-area as a seed, and segmenting the medical image on the basis of the seed.

Method, system and computer readable medium for automatic segmentation of a medical image

A method for segmenting organs on magnetic resonance (MR) images includes retrieving an MR image of a subject and generating a transformation matrix by segmenting bones on the MR image. An initial organ segmentation of the MR image is generated by registering a combined organ and bone atlas with the MR image using the transformation matrix. The MR image with initial organ segmentation may be shown on a display.

A method for generating an image includes obtaining a first image and a second image of an object of interest, generating a joint histogram using the first and second images, transforming the information in the histogram from histogram space to image space using a look-up table, and generating a color image using the information output from the look-up table. A system and non-transitory computer readable medium are also described herein.

Systems and methods for performing segmentation and visualization of multivariate medical images

A method for segmenting bones on magnetic resonance (MR) images includes retrieving an MR image and performing an enhancement process on the MR image to generate a bone enhanced MR image. The bone enhanced MR image is then registered to a computer tomography (CT) based bone atlas. An MR image with bone segmentation is generated by segmenting the bone enhanced MR image using the CT based bone atlas as a mask. The MR image with bone segmentation may be presented on a display.

A system and process for analyzing multidimensional data characterizing a least a portion of a subject is described. An input module accepts at least one multidimensional dataset which is derived from any of several types of data sources. A registration module accepts the dataset from the input module and registers the dataset from the input module to a selected anatomical model to provide a registered dataset. A processing module is coupled to the registration module and uses this in determining a core region and associated core region information, and computes threshold characteristics of the registered dataset. A segmentation module accepts the registered dataset and the core region information from the processing module, and segments the registered dataset to provide a segmented description of an organ from the registered dataset and core region information, where the segmented, registered dataset describes characteristics of the organ of the subject.

A system and process for combining multiple datasets to provide a composite dataset is described. The system includes a data collection tool, a computation engine and a memory coupled to the data collection tool and computer-readable code embodied on a computer-readable medium. The computer-readable code is configured so that when the computer-readable code is executed by one or more processors associated with the computation engine the computer-readable code causes the one or more processors to: (i) accept two or more datasets corresponding to distinct measurements of a subject, (ii) initiate processing of the two or more datasets, (iii) contemporaneously segment and register a combination of the two or more datasets to achieve a combined dataset, (iv) test for convergence of the combined dataset and (v) provide the combined dataset for analysis when the test for convergence indicates that the combined dataset has been registered and segmented.

The controller is also configured to segment the organ from the second set of slices.
