We describe PerspectaRAD, the first tool for the review and modification of external-beam radiation therapy treatment plans with a volumetric three-dimensional display (Perspecta 1.9, Actuality Medical, Bedford, MA, USA) and a dedicated software application (PerspectaRAD, Actuality Medical). We summarize multi-institution retrospective studies that compare the system's efficacy to the incumbent 2-D display-based workflow. Contributions include: visualizing the treatment plan in a volumetric 3-D display, modifying the beam locations and performing point-and-click measurement in 3-D with a 3-D physical interface, and simultaneously viewing volumetric projections of the native CT data and isodose contours. The plans are synchronized with the hospital treatment planning system, Pinnacle 3 (Philips Medical, WI, USA). In the largest of five studies, 33 plans were retrospectively randomized and replanned at three institutions, including 12 brain, 10 lung, and 11 abdomen / pelvis. The PerspectaRAD plan was as good as or better than plans created without PerspectaRAD 70% of the time. Radiation overdose regions were more likely to be obvious inside the target volume than when reviewed in the 2-D display alone. However, the planning time was longer with PerspectaRAD. The data demonstrate that PerspectaRAD facilitates the use of non-coplanar beams and has significant potential to achieve better plan quality in radiation therapy.

“…The 3-D display has been in clinical trials to show the difference between 2-D and 3-D when performing treatment planning (22) for cancer or navigating a catheter in a simulated heart. In either case, more accurate results were obtained with the 3-D display and additional insight provided.…”

Thermal Treatment of Tissue: Energy Delivery and Assessment IV

View full text Add to dashboard Cite

Thermal therapy as a treatment for cancer is a dynamic treatment epicenter, with a variety of technologies available and undergoing continuous improvement. Recent advances in technology and applications for thermal therapy give clinicians more power to affect larger volumes of tissue in less time. New radiofrequency (RF) and microwave (MW) systems have appeared recently, giving powerful tools for cancer therapy. Novel therapeutic ultrasound (US) technologies are being explored, but are presently not commercialized. Thermal therapy applicators that deliver power to the target in the patient will be reviewed for shape, size, and features. The operation and performance of various applicators will be discussed. In the goal of performance increase, several features have been commercialized in the evolution of the technology, including cooling, multiple applicator arrays, power modulation, and applicator deployment and shape change. To place recent progress into perspective, a historical review of some RF and MW applicators will be given. The work will cover modeling and simulations, as well as in-vitro, in-vivo, and clinical results.
