Object-pose-based initialization of an ultrasound beamformer

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