Hybrid imaging system for intraoperative, interventional and diagnostic applications

摘要

It is a combined nuclear- and ultrasound system for hybrid imaging (10) is provided, which comprises: a hand-guided nuclear radiation-detector (20), a hand-guided ultrasound probe (30), a nuclear-tracking system (40) for tracking of the nuclear radiation-detector (20) during the measuring a nuclear radiation and for obtaining nuclear radiation-detector-coordinate, the a position of the next nuclear radiation-detector in relation to an image coordinate system of a hybrid image, represent a ultrasonic tracking system (50) for tracking the ultrasound probe (30) during the recording of ultrasonic signals, so that ultrasound probes coordinates are obtained, which a position of the trailing ultrasound probe in relation to an image coordinate system of a hybrid image, and represent a data acquisition module (60), the nuclear radiation-detector-measurements, nuclear radiation-detector-coordinate, the ultrasonic signals from the ultrasound system (50), and ultrasound probes coordinates detected and used to an image coordinate system of a hybrid image, and a nuclear image reconstruction module (70) for reconstructing a nuclear-image from nuclear radiation-detector-measurements, ultrasonic signals nuclear radiation-detector-coordinate ultrasonic signal coordinate, and in the image coordinate system of a hybrid image. In addition, a method for hybrid imaging proposed.
