摘要： A system for Non-Contrast Agent enhanced MR imaging includes an MR image acquisition device for acquiring imaging datasets comprising one or more image slabs individually comprising multiple image slices. An image data processor processes data representing an acquired image slice to detect a predetermined anatomical feature of a patient by detecting an edge of the anatomical feature in response to detection of pixel luminance transitions. A patient support table controller automatically moves a patient table at a velocity adaptively and dynamically determined by, selecting data modifying table velocity from predetermined information associating an anatomical feature with table velocity modification data in response to detection of the anatomical feature and adaptively determining a table velocity using the modification data.

摘要： A system enhances MR imaging contrast between vessels containing dynamically flowing blood and static tissue using an MR imaging system. The MR imaging system, in response to a heart rate synchronization signal, acquires an anatomical preparation data set representing a spatially non-localized preparation 3D volume in response to a first magnetization preparation pulse sequence. The MR imaging system acquires a spatially localized anatomical imaging data set representing a second imaging volume. The MR imaging system subtracts slice specific MR imaging data of the spatially localized anatomical imaging data set from spatially and temporally corresponding slice specific imaging data of the anatomical preparation data set to derive blood flow indicative imaging data. The temporally corresponding slice specific imaging data comprises data acquired at a substantially corresponding cycle point within a heart beat cycle determined in response to said heart rate synchronization signal. The MR imaging system iteratively repeats the subtraction step for multiple adjacent slices individually comprising a spatially localized anatomical imaging data set to provide a three-dimensional imaging data set.

摘要： A system includes an image data processor for automatically processing data representing multiple patient anatomical images acquired in a single imaging scan. The images are acquired by, identifying multiple different anatomical elements in corresponding multiple different anatomical regions and identifying multiple different potentially pathology indicative features associated with the multiple different anatomical elements in response to first predetermined information associating different potentially pathology indicative features with corresponding different anatomical elements. The image data processor determines multiple different image acquisition methods for use in imaging the multiple different potentially pathology indicative features in response to second predetermined information associating different image acquisition methods with corresponding identified different pathology indicative features. An output processor collates images for output.

摘要： A system automatically concurrently performs an MR image study acquisition and supplementary image data acquisition. The system includes a detector for providing a signal indicating individual portions of an imaging scan using a first imaging method have ceased. An image data processor automatically concurrently interleaves imaging of a first anatomical portion using the first imaging method and supplementary imaging of a second anatomical portion using a different second imaging method, in response to the signal. The image data processor incorporates identifier data in data representing images acquired using the second imaging method identifying images acquired using the second imaging method differently from images acquired using the first imaging method.

摘要： An imaging system automatically determines a cardiac timing parameter for acquiring a cardiac image in a heart phase. An interface receives data identifying a heart image orientation for image acquisition. A repository of data associates, for acquisition of an image in a particular heart phase, different image orientations with corresponding different data items identifying respective corresponding particular acquisition points within an individual heart cycle relative to a start point of the heart cycle. An acquisition timing processor determines from the repository of data, a particular acquisition point within an individual heart cycle relative to the start point of the heart cycle, in response to the received data identifying the heart image orientation and uses the determined particular acquisition point to provide a synchronization signal for triggering acquisition of an image at the particular heart phase.

摘要： A system supports medical imaging compliance with guideline and reimbursement requirements using at least one repository and a compliance processor. The at least one repository associates information including, specific reimbursement requirements of a patient insurance company with an imaging protocol compliant with predetermined guidelines for imaging a particular anatomical feature and with a specific type of imaging device and with multiple different steps of the imaging protocol. The compliance processor uses the information in, determining whether a particular imaging protocol for imaging a particular anatomical feature of a particular patient on a particular type of imaging device is compliant with the guidelines and the reimbursement requirements and identifying at least one of, (a) a missing step and (b) an incorrect step, in the particular imaging protocol.
