摘要： A system employs an interventional tool (30), ultrasound imaging system and a multi-planar reformatting module (40). The interventional tool (30)has one or more image tracking points (31). The ultrasound imaging system includes an ultrasound probe (20)operable for generating an ultrasound volume image (22)of a portion or an entirety of the interventional tool (30)within an anatomical region.

摘要： A method, system, and program product are provided for x-ray pose recovery during an endoscopic procedure. An x-ray image is taken with a C-arm at a first pose, capturing a region of an endoscope with fiducials thereon. The C-arm is moved from the fist pose to a second pose at another viewing angle while maintaining the position of the endoscope. Anotherx-ray image is taken with the C-arm at the second C-arm pose, capturing the region of the endoscope with the fiducials thereon. The location of the fiducials on each x-ray image is determined using segmentation. An iterative optimization is performed using the locations of the fiducials in the two x-ray images to form two-dimensional projections of the three dimensional curve of the region of the endoscope with fiducials thereon to determine the three-dimensional translation and rotation of the C-arm from the first x-ray pose to the second x-ray pose.

摘要： An imaging correction system includes a tracked imaging probe(132) configured to generate imaging volumes of a region of interest from different positions. An image compensation module (115) is configured to process image signals from a medical imaging device associated with the probe and to compare one or more image volumes with a reference to determine aberrations between an assumed wave velocity through the region of interest and a compensated wave velocity through the region of interest. An image correction module(119)is configured to receive the aberrations determined by the image compensation module and generate a corrected image for display based on the compensated wave velocity.

摘要： Beamforming to image an object (310), such as an interventional tool, is enhanced by initializing the beamformer (308) with the object's location, and optionally its orientation. The initializing uses an estimate of the location/orientation. The estimate is derived from the output of one or more sensors (304, 306). These are disposed external to the imaging array (316) that operates with the beamformer. The estimate is made without the need for a result of any imaging based on data arriving by reflected ultrasound. One or more of the sensors may be attached to the object, which may be elongated, as in the case of a needle or catheter used in medical diagnosis and treatment. In some implementations, one or more of the sensors are attached to the imaging probe (302). The sensors may be, for example, ultrasound, electromagnetic, optical, or shape sensors. Alternatively, ultrasound transmitting transducers may be substituted for the ultrasound sensors.

摘要： 2010P01323WO 24 ABSTRACT: The invention relates to location determination apparatus for determining a location of a first object (2) like a catheter within a second object (3) being, for example, the heart of a person. The first object comprises a first ultrasound unit, and a second ultrasound unit (5) is located outside the second object. A location determination unit determines the location of the first object within the second object based on ultrasound signals transmitted 5 between the first ultrasound unit and the second ultrasound unit. This allows determining the location of the first object within the second object reliably in a way which is an alternative to using a transmission of electrical signals for determining the location and which may lead to an improved accuracy of determining the location. 10 Fig. 3

摘要： A calibration/surgical tool (90, 160) includes an electromagnetic sensor array (30) of two or more electromagnetic sensors in a known geometrical configuration. Electromagnetic tracking errors are characterized by a mapping of pre-operative absolute and relative errors based on a movement of a calibrated calibration/surgical tool (90, 160) through a pre¬ operative electromagnetic field. Using statistical mapping, a desired absolute error field (46) is measured either in the clinic as the part of daily quality control checks, or before the patient comes in or in vivo. A resulting error field (46) may be displayed to the physician to provide clear visual feedback about measurement confidence or reliability of localization estimates of the absolute errors in electromagnetic tracking.
