Abstract: Methods and apparatus for automatically assessing quality of imaging systems are disclosed. An example apparatus includes a processor configured to receive data from an imaging device; determine whether the received data corresponds to a test exam; in response to determining that the received data corresponds to the test exam, determine whether the test exam was correctly performed based on a comparison of the data to a validity criterion; and when the test exam was correctly performed, determine that the imaging system satisfies a performance criteria based on a comparison of a characteristic of the data corresponding to the performance indicator with a performance threshold; and a storage configured to store the performance indicator in conjunction with the data.

Abstract: System and methods for automatically identifying anatomical regions in medical images are disclosed. A signature is computed from one or more images of a patient. The signature comprises a water equivalent diameter distribution generated from one or more images of the patient. A best matching atlas element is identified from an atlas. The atlas includes a group of atlas elements, each atlas element includes landmarks associated with a set of image data, and a signature associated with the set of image data. The signature of the best matching atlas element matches the signature of the patient the best among the atlas. Landmarks of the best matching atlas element are projected onto an image of the patient. The method can be used on its own for anatomy localization or used in conjunction with another anatomy localization method to correct the result of another method.
