Locally optimum run-length compression of CT images without restriction on the pixel value.
Previously reported locally optimum run-length compression of CT images is only applicable to 12 bit images. In order to extend this method to images whose pixel values may vary from 8 bits per pixel to 16 bits per pixel, single byte coding is suggested. A search method is also suggested to make a reasonable determination of the length of non-compressible pixels. Experiments have shown that single byte coding is successful, giving compressed results which are comparable with previously reported results.
