Educational and review use only. Voxelis is not FDA-cleared and must not be used for primary diagnosis. Open a CT or MR study instantly โ local-first medical DICOM viewer for iPhone and iPad. WHAT'S NEW IN 1.5.3 An image-correctness release. โข Sample studies render correctly. The bundled CT was a damaged file that displayed as a white blur. It has been repaired, and every study now opens at a window derived from its own pixels rather than one fixed setting. โข Drag to window. With the WW/WL tool active, drag the image โ sideways for contrast, up for brightness. โข Anatomical orientation markers. A, P, R and L on the image edges, read from the study's own orientation data and rotating with the image. โข 12- and 14-bit studies decode correctly. The darkest tissue in these files used to be misread, washing the image out. โข Window values no longer carry a thousands separator. โข Larger zoom controls, real thumbnails in the series rail, and a technical readout that no longer sits on the anatomy. โข Now runs on iOS 17 and later.
