For Research in 3D Dosimetry for Radiotherapy
Vista™ reconstructs a 3D map of optical attenuation coefficients within an object suspended in the scanner’s region of interest. This is done by capturing a series of 2D optical projections through the region of interest while the object is being rotated and then using Feldkamp-filtered back projection to construct the 3D map. The base system is designed to work with radiochromic dosimeters such as Fricke gels which have an absorption peak at 590 nm. Different wavelengths are available on request for different dosimeters and for different applications.
