Title:
SYSTEM WITH INTERVENTIONAL ULTRASOUND MONITORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/161592
Kind Code:
A3
Abstract:
The present invention relates to a system (200) comprising an interventional device (228) with a plurality of ultrasound transducers (212a-c). The system (200) furthermore comprises one or more delay units (218, 220) arranged so that ultrasonic signals converted into electrical signals by the ultrasound transducers (212a-c) may be temporally separated so that the resulting difference in temporal delay between two received electrical signals at a point of combination correspond to a time span being larger than a characteristic temporal length of an excitation signal. The electrical signals may be combined into a single temporally extended signal so that a single receiver (222) may be able to receive the signals as a single temporally extended signal. Analysis of the single temporally extended signal may allow separation of signals originating from respective ultrasound transducers. In a particular embodiment, the system further comprises an ablation unit.
