Varian Medical System's latest medical linear accelerator is called the TrueBeam. This is a newly designed linac which is very different from their previous iX or Trilogy platform. It is equipped with kV-MV on-board imager, capable of IMRT, VMAT, respiratory gated treatments, and SBRTs. One of the major features of this linear accelerator is ability to remove flattening filter, thereby producing very high dose rates which can help in faster throughput and treatment delivery. This talk will give an overview of Emory's TrueBeam linear accelerator, which is the first of its kind in the state of Georgia.


Arsalan Siddiqi received his BS degree in Materials Science and Engineering from Georgia Tech. Later, he received his MS degree in Medical Physics from Georgia Tech as well. Mr. Siddiqi is currently a Medical Physics resident at Emory University's Department of Radiation Oncology. As a graduate student in MP program, he worked on gel dosimetry characterizing novel heat-sensitive gel using MRI. He has also investigated radio-sensitive gel to capture dose enhancement utilizing gold nanoparticles.
