The medical imagery is rendered according to the rendering mode. The requested medical imagery is displayed on the medical image viewer.

Abstract: Self-describing calibration targets for inclusion in medical imagery and automated quality control and calibration are provided. In various embodiments, a medical image is received. The medical image includes a calibration target in its field of view. A description of the calibration target is read from the calibration target. The description includes size and at least one color reference. Based on the description of the calibration target, correction parameters are determined for the medical image. The correction parameters include pixel shape correction parameters, scale correction parameters, contrast correction parameters, or color correction parameters.

Abstract: Carrying forward a spine label between studies is provided. In some embodiments, a first medical image of a subject's spine is provided. With the first image at least one label identifying a feature of the spine is provided. The first medical image is displayed to a user with the at least one label. At least one change is received from the user to the at least one label, yielding at least one updated label. The at least one updated label is applied to a second medical image. A three dimensional representation of the updated label is displayed.

Abstract: Multiple algorithm lesion segmentation using an atlas is provided. In various embodiments, a plurality of medical images are read from an image repository. Each of the plurality of medical images has a source modality. Each of the plurality of medical images is registered to an anatomical atlas. An anatomical region depicted in each of the plurality of medical images is determined thereby. Based upon the source modality and the anatomical region depicted in each of the plurality of medical images, one of a plurality of segmentation algorithms is selected for each of the plurality of medical images. The selected segmentation algorithms are applied to each of the plurality of medical images. The results of the selected segmentation algorithms are displayed.

Abstract: A system for viewing session takeover is provided. A plurality of user accounts have access to patient medical data images. A locking mechanism is operable by each user to prevent access to patient medical data until subsequent user authentication, without terminating a viewing session. A storage medium maintains configuration parameters associated with the primary user account. A session controller establishes a viewing session by retrieving the patient medical data for viewing on the display. The session controller applies the configuration parameters associated with the primary user account to the viewing session of the secondary user. A log records each user access associated with each viewing session.

Abstract: Multi-step vessel segmentation and analysis is provided. In various embodiments, a branch detection algorithm is applied to a medical image to determine a plurality of branches of a blood vessel appearing in the medical image. A plurality of segments of the blood vessel appearing in the medical image is determined. Each of the plurality of segments is bounded by one of the plurality of branches. An edge detection algorithm is applied piecewise to each of the plurality of segments. A composite blood vessel outline is formed from the piecewise edge detection.

Abstract: Automatic processing of medical imagery to remove personal health information is provided. In some various embodiments, a structured file containing a medical image and metadata is read. Identifying information of a device that captured the medical image is determined from the structured file. Based on the identifying information, locations within the medical image likely to include personal health information are determined. The locations within the medical image likely to include personal health information are obscured.
