DoseLab is a set of software programs for quantitative comparison of measured and computed radiation dose distributions. It is written in the Matlab programming language and is easily extensible to more general applications in radiation physics.

DoseLab version 3.05 has been released. Major changes include: Comments and Treatment type fields have been added to the patient information screen. The Patient ID number is also able to save non-numeric entries. You may now read treatment planning system files directly from DoseLab, without having to first convert them to TIF files. During the open file dialog, select the extension that represents your file type. You may now access previous dose comparisons without saving anything other than the MAT file. While opening a computed image, select a *.MAT extention. There is now a program to delete patient identification information from MAT files useful for sharing dose comparison information. The absolute and percent dose difference images use a new colormap that more clearly distinguishes sort of bad areas from really bad areas. The FTP program now handles file types other than TIF. Please see the new Ftp program.txt preference file for more information. You may now right click on images and lines and interactively change many of their properties. If an image has contour lines displayed on it, you may have to right click a corner of the image to see this menu. The single image analysis program now has a recently used files menu. A new comparison tool, 2D dose/distance histograms, has been added. This brings up an image showing a 2D histogram showing the percent of the comparison that has various values of distance to agreement and percent differences. This tool is useful for determining dose and distance criteria. The retrospective analysis program has been updated. Histograms are now shown that more clearly represent differences between selected parameters. For example, if you select dose normalization as functions of treatment month and treatment site, you will see a line graph that plots the normalization as a function of time and a histogram that shows the average normalization for each treatment site side-by-side. All the usual minor bug fixes. You can go to http://doselab.sf.net/download.html to download the latest version. As always, let me know if you have any questions or find any bugs. Nathan
