Horos and OsiriX are DICOM listeners and viewers that can manipulate 3-D data sets and export reconstructions of axial, equatorial and sagittal planes which bisect the affected eye as .jpg files. Other reconstructions of interest are the meridian and coronal planes which intersect the tumor apex. OsiriX predates Horos but is now a paid, FDA approved product. Horos (son of Osiris) is derived from the same code base as OsiriX but is free to use. The user interfaces are nearly identical.
These 6 reconstructions will be imported into Plaque Simulator and used to measure the size and shape of the eye and, in conjunction with ultrasound images and fundus photos, to determine the tumor size, shape and location within the eye.
