    摘要： A system acquires images in the presence of a contrast agent of relatively long persistence using a synchronization processor, image acquisition device and imaging controller. The synchronization processor provides an image acquisition trigger signal for acquiring images at a particular point within both a cardiac and a respiratory cycle in response to signals representing cardiac and respiratory cycles. The image acquisition device includes an assembly comprising a radiation emitter and detector rotatable about a patient for acquiring images of a portion of patient anatomy at different angles. The imaging controller initiates acquisition of data representing multiple images in the presence of a contrast agent of relatively long persistence by repetitively, initiating rotation of the assembly to an angle, acquiring an image at the angle in response to the trigger signal and incrementally increasing the angle.

    摘要： A method and system for registering ultrasound images and physiological models to x-ray fluoroscopy images is disclosed. A fluoroscopic image and an ultrasound image, such as a Transesophageal Echocardiography (TEE) image, are received. A 2D location of an ultrasound probe is detected in the fluoroscopic image. A 3D pose of the ultrasound probe is estimated based on the detected 2D location of the ultrasound probe in the fluoroscopic image. The ultrasound image is mapped to a 3D coordinate system of a fluoroscopic image acquisition device used to acquire the fluoroscopic image based on the estimated 3D pose of the ultrasound probe. The ultrasound image can then be projected into the fluoroscopic image using a projection matrix associated with the fluoroscopic image. A patient specific physiological model can be detected in the ultrasound image and projected into the fluoroscopic image.

    摘要： A method and system for autoregressive model based pigtail catheter motion prediction in a fluoroscopic image sequence is disclosed. Parameters of an autoregressive model are estimated based on observed pigtail catheter tip positions in a plurality of previous frames of a fluoroscopic image sequence. A pigtail catheter tip position in a current frame of the fluoroscopic image sequence is predicted using the fitted autoregressive model. The predicted pigtail catheter tip position can be used to constrain pigtail catheter tip detection in the current frame. The predicted pigtail catheter tip position may also be used to predict abnormal motion in the fluoroscopic image sequence.

    摘要： Registration of preoperatively acquired MRI images of soft parts to intraoperatively acquired X-ray images of soft parts is not possible. The invention shows a way of nevertheless using such preoperatively acquired images for superimposition with 2D projections of the soft parts, taking an indirect route via 3D/3D registration of images of the spinal column. For this purpose, 3D image data sets of the spinal column must be obtained separately on the one hand using MRI and on the other using the X-ray imaging system so that the 3D/3D registration produces a mapping rule which then also applies to the preoperatively acquired images of the soft part if the soft part images and the spinal images are acquired without intervening change in the patient position in the MRI scanner.

    摘要： The invention relates to a method and an apparatus for setting a dynamically adjustable position of an imaging system for providing an optimum view onto a moving object during a medical intervention. A time-resolved at least three-dimensional data record of the moving object is generated. A position of the imaging system for each period of time is determined from the time-resolved data record from which the optimum view onto a structure of interest of the moving object is produced and automatically setting a calculated position of the imaging system in real-time so that the optimum view onto the structure of interest can be shown at any time. Optionally prior to determining the position of the imaging system, a structure of interest of the moving object can be segmented with this structure being segmented for each period of time from the time-resolved data record.
