Radiology Assay (RAD)

In X-ray imaging, samples such as brain sections are put on radiochromic film and subsequently exposed. By comparing gray values on the film with calibration strips, the correct dosimetry can be calculated.

The Radiology Assay wraps (mice) brain sections onto each other and measures the gray value on the film for a selection of brain regions which have previously been defined in so called 'atlas sets'. Using the built-in calibration module, gray values are converted back into the desired output feature. The software also allows for the reanalysis or exclusion of sections that deviate from the expected 'average' brain section.

• Using the handy Atlas Tool, brain regions can be outlined and organized in atlas sets, which are stored for reuse in later analysis runs.
• The Calibration Tool lets the user set up calibration curves for strips used during X-ray exposure. Gray values can be mapped onto different output features.
• Post-analysis validation is straightforward thanks to the included visualization and reanalysis modules. Output data are collected in neatly organized text files, which can be imported in spreadsheet software such as MS Excel.
