The roles of volumetric imaging, beam optimization, and plan evaluation are all vital to the program. Photon beam delivery, being the endpoint, is an ever evolving and important segment. These devices have also increased treatment accuracy and efficiency. Multi-leaf collimation provides customized beam definition by computer control of tungsten leaves which configure the treatment shape. This efficient device has allowed treatment of more daily fields which is key to dose escalation.
Dynamic wedge provides computer control of a collimating jaw to move dynamically during irradiation.
This application provides gradient dose distributions. Dual asymmetric jaws provide computerized designation of collimators, allowing precision beam matching. Portal imaging delivers on-line verification of the treatment, detecting beam accuracy and patient motion aspects. As part of the 3D conformal program for radiation oncology, this research group is also investigating the use of multileaf collimation for electrons.
