摘要： A controller for maintaining alignment of X-Ray imagery and ultrasound imagery includes a memory that stores instructions, and a processor that executes the instructions. When executed by the processor, the instructions cause the controller to execute a process that includes receiving data from an X-Ray system used to perform X-Ray imaging, and receiving data from an ultrasound imaging probe used to perform ultrasound imaging. The process executed by the controller also includes registering imagery based on X-Rays to imagery from the ultrasound imaging probe based on an X-Ray image of the ultrasound imaging probe among the imagery based on X-Rays, and detecting, from the data from the ultrasound imaging probe, movement of the ultrasound imaging probe.

摘要： An image registration system (111) for registering a live stream of ultrasound images (112) of a beamforming ultrasound probe (113) with an X-ray image (114) is described. The image registration (111) system identifies, from the X-ray image (114), the position of a medical device (116) represented in the X-ray image (114); and determines, based on ultrasound signals transmitted between the beamforming ultrasound probe (113) and an ultrasound transducer (115) disposed on the medical device (116), a location of the ultrasound transducer (115) respective the beamforming ultrasound probe (113). Each ultrasound image from the live stream (112) is registered with the X-ray (114) image based on the identified position of the medical device (116). The registration includes determining an offset from said identified position that is based on i) a predetermined spatial relationship of the ultrasound transducer (115) respective the medical device (116) and ii) the determined location of the ultrasound transducer (115) respective the beamforming ultrasound probe (113).

摘要： A steerable multi-plane ultrasound imaging system (MPUIS) for steering a plurality of intersecting image planes (PL 1..n ) of a beamforming ultrasound imaging probe (BUIP) based on ultrasound signals transmitted between the beamforming ultrasound imaging probe (BUIP) and an ultrasound transducer (S) disposed within a field of view (FOV) of the probe (BUIP). An ultrasound tracking system (UTS) causes the beamforming ultrasound imaging probe (BUIP) to adjust an orientation of the first image plane (PL 1 ) such that a first image plane passes through a position (POS) of the ultrasound transducer (S) by maximizing a magnitude of ultrasound signals transmitted between the beamforming ultrasound imaging probe (BUIP) and the ultrasound transducer (S). An orientation of a second image plane (PL 2 ) is adjusted such that an intersection (AZ) between the first image plane and the second image plane passes through the position of the ultrasound transducer (S).

摘要： A controller for displaying a puncture site of an intra-atrial septum for heart repairs includes a memory and a processor (710). The processor (710) executes instructions (784) to perform a process based on image data of a heart that includes a mitral valve and an intra-atrial septum. The process includes defining a mitral valve annulus plane along a mitral valve annulus of the mitral valve and a normal vector perpendicular to the mitral valve annulus plane. The process also includes defining an offset plane that intersects with the intra-atrial septum and that is parallel to the mitral valve annulus plane. A safe zone for the puncture site is identified and displayed on the intra-atrial septum. The safe zone is between a lower boundary plane (456) and an upper boundary plane (455) that are each parallel to the offset plane by specified distances.

摘要： The present invention relates to supporting an interventional procedure involving a device, such as a cardiovascular procedure. First and second image data acquired using different imaging apparatus, for example X-ray and ultrasound image data, are co-registered. A device is firstly identified in 2D X-ray images; corresponding identification information is then used to generate a view from 3D ultrasound image data that includes a cross-section of the device to be identified subsequently. Following the identification, a 3D position and orientation of the device are available. Such information may advantageously be used in setting up optimal ultrasound views for image-based guidance of the ongoing procedure.
