    摘要： A system and method for obtaining perfusion images is disclosed. The system and method includes hardware and software for determining physiological characteristics of a patient and determining imaging parameter values for an imaging modality based on the patient's physiological characteristics. The system also includes a controller operative to receive the imaging parameter values for controlling an X-ray device. The X-ray device is coupled with the controller and acquires projection images of the patient, and outputs the projection images to a perfusion evaluation computer for evaluating the perfusion of an region of interest represented in the projection images. The perfusion rate of the region of interest is then output to an output device, such as a display or printer.

    摘要： In a method and apparatus for optically-based acquisition of slice images from a vessel of a subject, and for combining the slice images to provide an intuitively recognizable visualization of a pathology in the vessel, slice images of the vessel are acquired during pullback of an optical probe of the optically-based slice imaging system, while simultaneously acquiring an ECG signal from the subject. The slice images and the ECG signal are registered, and slice images acquired at a selected cardiac phase are combined into a scene. The slice images in the scene are subjected to a first data transformation to shift the vessel midpoint in each slice image to the image center of each slice image. After the first data transformation, the slice images in the scene are subjected to a second data transformation to produce the visualization. The second transformation, for example, can be a curved planar reformation to allow the vessel to be shown in longitudinal section.

    摘要： An optical coherence tomography system includes a catheter in which is arranged a plurality of light conducting fibers. It further includes a plurality of optical units. Light from the proximal end to the distal end and signals from the distal end to the proximal end can be transmitted simultaneously in different fibers. Time is saved through the simultaneous signal processing of signals from different fibers. That is advantageous particularly in the imaging, by means of coherence tomography, of blood vessels that have to be occluded for said imaging.

    摘要： A method of optimized diagnosis and treatment of suspected myocardial infarctions is described. The patient having possible coronary artery disease is transferred to a treatment room with an imaging modality suitable for obtaining computed tomographic (CT)-like images. Such images are obtained as radiographic image data, with or without contrast agent, and used in the medical diagnosis. If minimally invasive therapy such as percutaneous transluminal coronal angioplasty (PTCA) is indicated, the patient is prepared for the procedure in the same room, and the procedure performed, where the imaging modality is used to obtain fluoroscopic images to guide the PTCA procedure, or to assess the results of the procedure. The imaging modality may be mounted to a first positioning robot, and a second robot may facilitate the positioning or movement of the patient.
