The digital imaging systems that I have been linking to provide raw 12 and 14 bit grey scale, this is then processed to provide contrast enhancement so that medical inserts can easily be seen even with low dosage X-ray monitoring. The advantage is that only one ADC/DAC pair is required. Colour is added to the processed image, when a drop to 8 bit can be accepted. The x-ray systems had to be very high resolution 12 bit before acceptable as a replacement to film in a number of situations. -- Lester Caine ----------------------------- L.S.Caine Electronic Services _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
