    摘要： A system and method to identify, convey, and reduce the risk of hip dislocations following hip replacement surgery. Preoperative images are used to identify the pelvic tilt of a patient while the patient is in a sitting position, a standing position, and a supine position. Based on the pelvic tilt and pelvic mobility depicted in the preoperative images, the system can identify a quantitative and/or qualitative risk of hip dislocation when the patient is seated, standing, and lying. During surgery, an intraoperative image can confirm the acetabular cup orientation once implanted and the system can determine the risk of hip dislocation when patient is in the supine position. The system can also extrapolate the dislocation risk when the patient is seated and standing based on acetabular cup position and orientation depicted in the intraoperative image.

    摘要： A noninvasive patient-specific method is provided to aid in the analysis, diagnosis, prediction or treatment of hemodynamics of the cardiovascular system of a patient. Coronary blood flow and pressure can be predicted using a 3-D patient image-based model that is implicitly coupled with a model of at least a portion of the remaining cardiovascular system. The 3-D patient image-based model includes at least a portion of the thoracic aorta and epicardial coronaries of the patient. The shape of one or more velocity profiles at the interface of the models is enforced to control complex flow features of recirculating or retrograde flow thereby minimizing model instabilities and resulting in patient-specific predictions of coronary flow rate and pressure. The invention allows for patient-specific predictions of the effect of different or varying physiological states and hemodynamic benefits of coronary medical interventions, percutaneous coronary interventions and surgical therapies.

    摘要： A local user obtains data on the response of internal tissues of a subject to a non-invasive imaging system, choosing sensor positions according to a geometric display. The data obtained are evaluated with respect to predefined quantitative values. The process of obtaining and processing the internal tissue response data is repeated until an image meeting predetermined image quality characteristics is obtained. Specific or general content of the image may be restricted by the local processor, with a distal processor receiving the obtained image data, so as to limit specific or general types of image information from being viewed by the local user, such as image data that can be used to identify the sex of a fetus within the subject.

    摘要： A computer-implemented method is for performing at least one medical imaging procedure using an imaging modality. The medical imaging procedure is performed under remote supervision. An embodiment of the method includes acquiring with a computing unit data on the medical imaging procedure to be performed; acquiring with the computing unit data on at least one expert operator, located at a workplace remote from the imaging modality; matching data on the medical imaging procedure with data on the expert operator; assigning at least one expert operator to the medical imaging procedure based on the matching; and providing a communication channel between the imaging modality and the remote workplace.
