Actuality Systems received the "best in show" award at the 2005 conference of the American Society for Therapeutic Radiology And Oncology (ASTRO). Actuality produces a 3D volumetric display that can make computer-generated models appear as solid objects inside of a volleyball-size clear plastic dome. The models appear to be real, space-filling objects that can be seen by multiple users without the use of goggles or other auxiliary devices (see photograph). The device supports resolutions up to 768 by 768 pixels at a depth of 198 slices in 8 colors. The slices are projected 24 times a second onto a translucent screen that rotates inside of the dome at 730 revolutions per minute, which creates the illusion that the projected objects are real. Its application in medicine includes surgical planning, interventional imaging such as aligning a surgeon's scalpel or treatment device with a real-time 3D scan, image-guided tumor ablation, breast biopsy, catheter visualization, and planning radiation treatment for cancer patients.
