超音波信号を使用する介入デバイス位置決め

Document Type and Number:

Japanese Patent JP7222070

Kind Code:

B2

Abstract:

A system for determining a position of an interventional device (11) respective an imaging field (B_1..k) corresponding to a type (T_1..n) of a beamforming ultrasound imaging probe (13) currently connected to an ultrasound imaging system (14). The position is determined based on ultrasound signals transmitted between the beamforming ultrasound imaging probe (13) and an ultrasound transducer (15) attached to the interventional device (11). An image reconstruction unit (IRU) provides a reconstructed ultrasound image (RUI) corresponding to the imaging field (B_1..k). A position determination unit (PDU) receives input indicative of the type (T_1..n) of the beamforming ultrasound imaging probe (13) currently connected to the ultrasound imaging system (14). The position determination unit (PDU) also computes a position (LAP_{TOFSmax, θIPA}) of the ultrasound transducer (15) respective the imaging field (B_1..k). Computing the position (LAP_{TOFSmax, θIPA}) comprises selecting from a group of beam sequences corresponding to a plurality of imaging probe types (T_1..n) a beam sequence corresponding to the type (T_1..n) of the beamforming ultrasound imaging probe (13) currently connected to the ultrasound imaging system (14) and assigning detected ultrasound signals to the selected beam sequence.
