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. โ€ข 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. โ€ข Drag to window. With the WW/WL tool active, drag the image โ€” sideways for contrast, up for brightness. โ€ข 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. โ€ข 12- and 14-bit studies decode correctly. The darkest tissue in these files used to be misread, washing the image out. โ€ข Window values no longer carry a thousands separator. โ€ข Larger zoom controls, real thumbnails in the series rail, and a technical readout that no longer sits on the anatomy. โ€ข Now runs on iOS 17 and later.
