We are delighted to partner with the University of Iowa on this research collaboration agreement to develop ultra-high precision IMPT(*). This project really meets our objective to bring meaningful clinical innovations to our clinical partners for the benefit of patients.

The Dynamic Collimation System (DCS) (**) was recently developed and presented by the University of Iowa at the American Association of Physicists in Medicine (AAPM) meeting in Austin, Texas.

The Dynamic Collimation System is an innovative device developed by University of Iowa Carver College of Medicine faculty members (***) to improve dose conformity in IMPT. The applications for the DCS could extend to many tumor sites and is expected to improve hypo-fractionated treatments in Proton Therapy on a five-year horizon.

Daniel Hyer, Ph. D., Proton Therapy Technical Director and Clinical Assistant Professor of Radiation Oncology, told us that the conformity of PBS dose distributions, which are already very sharp, can still be improved with the addition of collimation. The novel device that is under development, called the Dynamic Collimation System (DCS), is capable of providing layer-by-layer collimation. The DCS is also designed with a much smaller footprint than an Multi Leaf Collimator (MLC), allowing for a small air gap to maximize the benefits of collimation in proton therapy.

This project is very exciting for all the involved partners who are dedicated advance proton therapy and enhance the quality of the treatment for the patients.
