20120121153 | Method and System for Retrospective Image Combination Under Minimal Total Deformation Constrain for Free-Breathing Cardiac Magnetic Resonance Imaging With Motion Correction - A method and system for retrospective image combination for free-breathing magnetic resonance (MR) images is disclose. A free-breathing cardiac MR image acquisition including a plurality of frames is received. A key frame is selected of the plurality of frames. A deformation field for each frame to register each frame with the key frame. A weight is determined for each pixel in each frame based on the deformation field for each frame under a minimum total deformation constraint. A combination image is then generated as a weighted average of the frames using the weight determined for each pixel in each frame. | 05-17-2012 |
20120235679 | MOTION COMPENSATED MAGNETIC RESONANCE RECONSTRUCTION IN REAL-TIME IMAGING - Magnetic resonance reconstruction includes motion compensation. Inverse-consistent non-rigid registration is used to determine motion between shots. The motion is incorporated into reconstruction. The incorporation compensates for the motion resulting from the period over which the MR data is acquired. | 09-20-2012 |
20120283546 | Automatic or Semi-Automatic Whole Body MR Scanning System - 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. | 11-08-2012 |
20130297331 | Medical Imaging Guideline Compliance System - 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. | 11-07-2013 |
20140070803 | MR Parallel Imaging System Reducing Imaging Time - An MR imaging system uses multiple RF coils, for reducing image acquisition time, suitable for chemical exchange saturation transfer (CEST) imaging. Multiple RF (Radio Frequency) coils provide CEST imaging preparation in an anatomical volume by providing multiple interleaved RF pulses. The multiple interleaved RF pulses provide substantially increased RF pulse sequence duty cycle in the multiple RF coils relative to a duty cycle provided by a single coil of the multiple RF coils. The multiple RF coils subsequently provide RF excitation pulses in a reduced anatomical volume using k-space undersampling in an accelerated imaging method using the multiple RF coils and enable subsequent acquisition of associated RF echo data for deriving a CEST image. | 03-13-2014 |
20140121496 | Automatic System for Timing In Imaging - 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. | 05-01-2014 |
20140129248 | USAGE BASED SYSTEM FOR MONITORING A MEDICAL IMAGING DEVICE - A system for profiling operational usage associated with a plurality of medical imaging devices includes an information container processor, a database, a data analyzer module, and an output processor. The information container processor is configured to acquire operational data from each of a plurality of customer entities. The operational data acquired from each respective customer entity may include, for example, an identification of a imaging device used by a respective customer entity; a configuration setting associated with the imaging device; and an identification of one or more of an imaging scanning method utilized by the imaging device, an anatomical region imaged by the imaging device, and a medical condition investigated using the imaging device. The database is configured to store the operational data acquired from each respective customer entity. The data analyzer module is configured to generate one or more usage inquiries; using the database and the usage inquiries, derive one or more findings regarding the operational data acquired from each respective customer entity; and identify a significant finding included in the one or more findings. The output processor is configured to communicate data indicating the significant finding to a destination. | 05-08-2014 |
20150286780 | Imaging Protocol Optimization With Consensus Of The Community - A method for optimizing imaging protocols usage based on community voting includes a computer storing standard imaging protocol data associated with an imaging device type in a protocol database. The computer receives a request to modify the standard imaging protocol data. Next, the computer presents information from the request on a website accessible by a plurality of community members. Vote values are received from the community members via the website, each respective vote value selected from a range of values with a minimum value indicating rejection of the modified imaging protocol data and a maximum value indicating acceptance of the modified imaging protocol data. The computer then determines whether a consensus decision exists among the vote values. If the consensus decision exists, the computer determines whether to accept or reject the request to modify the standard imaging protocol data based on the consensus decision. | 10-08-2015 |
