摘要：
An artery mapper is attached over a target artery, and includes a sensor array that detects pressure changes corresponding to pulsatile flow through the artery. The signals from the sensor array are processed to identify signals having a frequency within a predetermined pulsatile range, and that define an elongate path across the sensor array. A display is provided directly over the sensor array. A digital controller circuit receives the signals from the detector array, and produces an image on the display directly over the detected signals, providing the practitioner with an image corresponding to the location of the artery, to facilitate cannulation of the artery.
