Display of two-dimensional ultrasound fan

摘要

A medical imaging system for imaging a patient's body includes a catheter having a position sensor and an ultrasonic imaging sensor wherein the position sensor transmits electrical signals indicating positional information of the catheter in the patient's body and the ultrasonic imaging sensor transmits ultrasonic energy at a target in the patient's body, receives ultrasonic echoes reflected from the target and transmits signals relating to the reflected ultrasonic echoes. A positioning processor is connected to the catheter for determining its positional information based on the electrical signals transmitted by the position sensor. The system includes a display and an image processor connected to the catheter, the positioning processor and the display. The image processor generates an ultrasonic image of the target and depicts the generated ultrasound image on the display in the same orientation as the catheter in the patient's body based on positional information from the position sensor.

1. A medical imaging system for imaging a patient's body, the system comprising:
a catheter comprising a position sensor and an ultrasonic imaging sensor, the position sensor transmitting electrical signals indicative of positional information of a portion of the catheter configured to be within the patients' body and the ultrasonic imaging sensor transmitting ultrasonic energy at a target in the patient's body, receiving ultrasonic echoes reflected from the target in the patient's body and transmitting signals relating to the ultrasonic echoes reflected from the target in the patient's body; a positioning computer processor operatively connected to the catheter for determining positional information of the portion of the catheter based on the electrical signals transmitted by the position sensor; a display; and an image computer processor operatively connected to the catheter, the positioning processor and the display, the image processor generating an ultrasonic image of the target based on the signals transmitted by the ultrasonic sensor and depicting in real-time the generated ultrasonic image on the display in a same orientation as an orientation of the portion of the catheter in the patient's body based on positional information derived from the position sensor and an orientation icon depicted on the display in a same orientation as the ultrasonic image depicted on the display.
