Embodiment Construction

[0032] refer to figure 1 , computer system 10 performs partially or fully automated detection of anatomical landmarks 46 in anatomical data. Computer system 10 accesses image data 20 representing the patient's anatomy and identifies features of image data 20 indicative of, for example, a medical condition of the patient or a group of patients to which the patient belongs. Based on the identified features, computer system 10 selects a reference model that corresponds to the patient's anatomy. The reference model indicates, for example, image processing parameters and regions where anatomical landmarks are likely to be located. Using the reference model, computer system 10 generates segmented image data 42 representing tissue boundaries and determines the location of anatomical landmarks 46 relative to segmented image data 42 .

[0033] The computer system 10 can use image data from multiple scans of the patient's anatomy to enhance detection of anatomical landmarks. For exam...

Abstract

A method includes accessing image data representing tissue and identifying one or more features of the tissue indicated by the image data. A model for the tissue is selected based on the one or more identified characteristics. The image data is segmented, and one or more anatomical landmarks of tissue indicated by the segmented image data are identified using the model.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and full benefit of US Provisional Application Serial No. 61 / 373630, filed August 13, 2010, entitled "Automatic Detection of Anatomical Landmarks," which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to the detection of anatomical landmarks. Background technique [0004] Information about the location of anatomical landmarks may be useful, for example, for diagnosing disease and establishing surgical alignment. In some cases, anatomical landmarks in medical images are manually detected. Manual detection of anatomical landmarks can be time-consuming and subject to human error and subjectivity. Contents of the invention [0005] In one general aspect, a method includes detecting anatomical landmarks in image data. The imaging data includes one or more images of tissue, and a location corresponding to an anatomical feature...
