The database contains 10 different types of images with bit rates varying from 8 to 16 bits per pixel. The total number of test images was about 3000, originating from 125 different patient studies. Methods used for compressing the images include seven methods designed for grayscale images and 18 ordinary general-purpose compression programs. Furthermore, four compressed image file formats were used. The results show that the compression ratios strongly depend on the type of the image. The best methods turned out to be TMW, CALIC and JPEG-LS. The analysis step in TMW is very time-consuming. CALIC gives high compression ratios in a reasonable time, whereas JPEG-LS is nearly as effective and very fast. }, isbn = {0895-6111}, author = {Juha Kivijarvi and Tam{\'a}s Ojala and Timo Kaukoranta and Attila Kuba and L{\'a}szl{\'o} G{\'a}bor Ny{\'u}l and Olli Nevalainen} } @booklet {1086, title = {The Comparison of Lossless Compression Methods in the Case of a Medical Image Database}, year = {1998}, month = {1998///}, author = {Juha Kivijarvi and Tam{\'a}s Ojala and Timo Kaukoranta and Attila Kuba and L{\'a}szl{\'o} G{\'a}bor Ny{\'u}l and Olli Nevalainen} } @conference {1310, title = {Lossless Image Compression in SZOTE-PACS}, booktitle = {16th EuroPACS Annual Meeting}, year = {1998}, month = {Oct 1998}, pages = {95 - 98}, publisher = {*}, organization = {*}, address = {Barcelona}, author = {L{\'a}szl{\'o} Martonossy and L{\'a}szl{\'o} G{\'a}bor Ny{\'u}l and Antal Nagy and Attila Kuba and Olli Nevalainen and L{\'a}szl{\'o} Csernay}, editor = {Joaquim Piqueras and Joan-Carles Carreno} } @conference {1026, title = {Lossless Image Compression in SZOTE-PACS}, booktitle = {16th EuroPACS Annual Meeting}, year = {1998}, month = {Oct 1998}, pages = {95 - 98}, publisher = {*}, organization = {*}, address = {Barcelona}, author = {L{\'a}szl{\'o} Martonossy and L{\'a}szl{\'o} G{\'a}bor Ny{\'u}l and Antal Nagy and Attila Kuba and Olli Nevalainen and L{\'a}szl{\'o} Csernay}, editor = {Joaquim Piqueras and Joan-Carles Carreno} }
