A new architecture of the Digital Scan Converter (DSC) for the linear-scan ultrasound medical imaging systems is proposed and its hardware implementation is reported.
While the convential DSC merely displays the acquired data and does not allow access to the frame memory, it is possible, in the new system, to access to the frame memory for further imaging processing so as to obtain useful information for medical diagnosis.
Image processing can be performed either by a special purpose processor, or by VAX 11/780.
The system is made to operate asyncronously to increase the frame rate with tags assigned to the data.
The proposed DSC was designed to be used without much modification for the sector scan system as well.
