Ultrasound system and method for imaging and/or measuring displacement of moving tissue and fluid

摘要

A system and method for improved imaging is disclosed. An exemplary system provides a peripheral ultrasound system connected to a host computer with a plug-and-play interface such as a USB. An exemplary system utilizes a dedicated graphics processing unit such as a graphics card to analyze data obtained from a region of interest to produce an image on one or more output units for the user's viewing. Based on the image displayed on the output units, the user can determine the velocity of the moving tissue and fluid. The system of the present invention can be used to produce a Doppler color flow map or for power Doppler imaging.

主权项

1. A method of obtaining a diagnostic image and estimating the displacement of moving tissue and fluid, the method comprising:
coupling a transducer probe to a region of interest; transmitting ultrasound energy from the transducer probe to the region of interest; receiving reflected ultrasound energy from the region of interest at the transducer probe, the reflected ultrasound energy comprising at least a portion of the ultrasound energy transmitted by the probe; delivering the reflected ultrasound energy received by the transducer probe to a demodulator for demodulation into data readable by a central processing unit of a host computer; delivering the data to the central processing unit; delivering the data to a dedicated graphics processing unit from the central processing unit; processing the data on the dedicated graphics processing unit and not on the central processing unit, the processing comprising estimating a displacement of moving tissue and fluid in the region of interest.
