IMPROVED SCAN DISPLAY

摘要

A method and apparatus for forming an image of a target from echo return data in an ultrasound system which incorporates a commercially available handheld data processing device of a type including a display, a processor and an I/O port. A probe unit containing an ultrasound transducer is moved over a body to be imaged, transmitting ultrasound energy into the body. The probe Includes a sensor adapted to provide Information about the position and/or orientation of the probe unit, which may be a gyroscope. Echo return data received by the ultrasound transducer Is combined with the sensor output to produce a plurality of scanlines each including echo intensity data and information defining the position and/or orientation of the scanline. There is then calculated a transform adapted to map the scanlines to a plane of best fit; which is applied to the scanlines. The transformed data is mapped to a raster image the resultant image Is displayed.
