SHAPE INJECTION INTO ULTRASOUND IMAGE TO CALIBRATE BEAM PATTERNS IN REAL-TIME

摘要

A system for highlighting an instrument in an image includes a probe (122) for transmitting and receiving ultrasonic energy to and from a volume and a marker device (120) configured to respond to a received ultrasonic signal and emit an ultrasonic signal after a delay. The ultrasonic signal includes one or more pulses configured to generate a marker, when rendered, of a given size at a position within an image. A medical instrument (102) is disposed in the volume and includes the marker device. A control module (124) is stored in memory and is configured to interpret the ultrasonic energy received from the probe and from the marker device to determine a three dimensional location of the medical instrument and to highlight the three dimensional location of the marker device with the marker in the image.

1. A system for injecting a shape in an image, comprising:
a probe for transmitting and receiving ultrasonic energy to and from a volume; a marker device configured to respond to a received ultrasonic signal and emit an ultrasonic signal after a delay, the ultrasonic signal including one or more pulses configured to generate a marker, when rendered, of a given size at a position within an image; a medical instrument disposed in the volume and including the marker device; and a control module stored in memory and configured to interpret the ultrasonic energy received from the probe and from the marker device to determine a three dimensional location of the medical instrument and to highlight the three dimensional location of the marker device with the marker in the image.
