Abstract
The preferred embodiment includes a method and system for processing ultrasound data during or after compression. Various compression algorithms, such as JPEG compression, are used to transfer ultrasound data. The ultrasound data may include image (i.e. video data) or data obtained prior to scan conversion, such as detected acoustic line data or data complex in form. Compression algorithms typically include a plurality of steps to transform and quantize the ultrasound data. Various processes in addition to compression may be performed as part of one or more of the compression steps. Furthermore, various ultrasound system processes typically performed on uncompressed ultrasound data may be performed using compressed or partially compressed ultrasound data. Operation on compressed or partially compressed data may more efficiently provide processed data for generation of an image. Fewer operations are required by one or more processors when operating on compressed or partially compressed data than for uncompressed or non-compressed data. In one embodiment, partially compressed data may be input into a look-up table for contrast enhancement. In another embodiment, partially compressed data is high passed filtered.
