Title:

SYSTEM AND METHOD OF ACQUIRING BLOOD-VESSEL DATA

Document Type and Number:

WIPO Patent Application WO2004017821

Kind Code:

A3

Abstract:

A system and method is provided for substantially synchronizing the acquisition of blood-vessel data to an identifiable portion of heartbeat data. Specifically, a data-gathering device is adapted to acquire heartbeat data and blood-vessel data from a heart-monitoring device and a data-gathering probe, respectively. In a preferred embodiment of the present invention, the blood-vessel data is acquired during a cyclical portion of the heartbeat data. By identifying a cyclical (or commonly reoccurring) portion of the heartbeat data and acquiring blood-vessel data during this cyclical portion (or during an interval that substantially corresponds thereto), the blood vessel can be analyzed as if it were standing still -- i.e., not expanding and relaxing. In one embodiment of the present invention, the heart-monitoring device (130) includes an EKG device, the data-gathering device (110) includes an intra-vascular ultrasound (IVUS) device (212) and a computing device (214), and the data-gathering probe (140) includes at least one transducer. In another embodiment of the present invention, the data-gathering system further includes a retraction device (120) adapted to move the data-gathering probe though a blood vessel at a substantially steady speed.
