INTERLEAVED IMAGING AND TRACKING SEQUENCES FOR ULTRASOUND-BASED INSTRUMENT TRACKING

A method for tracking an interventional medical device in a patient includes interleaving, by an imaging probe external to the patient, a pulse sequence of imaging beams and tracking beams to obtain an interleaved pulse sequence. The method also includes transmitting, from the imaging probe to the interventional medical device in the patient, the interleaved pulse sequence. The method further includes determining, based on a response to the tracking beams received from a sensor on the interventional medical device, a location of the sensor in the patient. 一种用于跟踪患者中的介入医学设备的方法，包括由位于所述患者外部的成像探头将成像波束和跟踪波束的脉冲序列进行交错以获得交错脉冲序列。所述方法还包括将所述交错脉冲序列从所述成像探头发送到所述患者中的所述介入医学设备。所述方法还包括基于对从所述介入医学设备上的传感器接收的所述跟踪波束的响应来确定所述传感器在所述患者中的位置。
