I joined CTRC and UTHSCSA in 2006 as a Medical Physicist and adjunct Assistant Professor at the Department of Radiation Oncology. My duties are divided between clinical medical physics services and academic services (teaching and mentoring of students) to the Graduate School of Biomedical Sciences.
The clinical responsibilities at the Radiation Oncology department of CTRC include a broad range of radiation therapy physics services from external beam therapy and brachytherapy to advanced treatment deliveries such as stereotactic radiosurgery procedures. Apart from the routine clinical physics services, I was in charge of the implementation of the RapidArc and SmartArc deliveries as well as their respective Quality Assurance (QA) procedures. CTRC was the first center in San Antonio to treat patients with the RapidArc technology. At present, I am developing new patient specific IMRT QA methodology and I am testing and evaluating state of the art equipment for patient specific QA. One of these methods is the use of Electronic Portal Imaging Devices for IMRT QA and the other one is using multi-leaf collimator log files along with daily imaging studies.
In addition to the clinical services at CTRC, I am responsible for the medical physics services of the South Texas Veteran Affairs Department of Radiation Oncology at Wilford Hall Medical Center. At WHMC, I supervise a team of 5 people (four therapists and one dosimetrists) and we are responsible for the treatment of approximately 25 patients daily. Over the last year, the Department of Radiation oncology at VA has moved to its new location where I was involved in the planning of the department and the selection of equipment and software. Moreover, I accepted and commissioned the newly installed linear accelerator and the respective treatment planning software radiation beam models. The new linear accelerator is capable of volumetric imaging for patient positioning and has advanced treatment delivery capabilities.
CTRC is a high standard radiation oncology facility that meets requirements set by various radiation therapy accrediting agencies (ACR, RPC, etc) in order to provide the highest quality of patient care. Due to the latest advances in technology of radiation delivery and QA, new standards have been set by such national and international agencies in order to meet accreditation requirements. It is one of my goals to work towards improvement of patient safety and quality assurance procedures of the radiation equipment at CTRC in order to meet new standards set.
My educational duties are multifold. I teach, direct and co-direct graduate courses of the Graduate School of Radiological Sciences and I am mentoring PhD and MS students. CTRC has obtained accreditation for the Medical Physics Residency program since 2009 for which I am the associate director and I am training medical physics residents. I also, teach for the Dosimetry Review Course. The three PhD and one MS student graduated under my supervision are working as faculty or junior medical physicists. Currently I am supervising one PhD and one MS student?s research projects on patient safety and novel radiation therapy delivery techniques. My educational activities have further increased with the addition of the Doctor of Medical Physics program that since September 2014. This program is directed towards graduate students who are seeking a clinical medical physicist carrier. We are currently in the 4th year of the DMP program and we have about 16-20 students enrolled to the program each year. The students are completing their training during their clinical rotation at CTRC.
The new Doctor of Medical Physics (DMP) degree that is available by the Graduate School of Biomedical Sciences allows more students to acquire medical physics training. My role as a co-chair of the Committee Of the Graduate School is to assist the director of medical physics at CTRC as well as the director of the Graduate School in order to make operations for the new program as smooth as possible. I will continue my didactic responsibilities (teaching and directing of graduate courses) and expand them to the DMP students. Moreover, I will be assisting with the 3rd and 4th year DMP students? and Medical Physics Residents clinical training at CTRC.
My research projects were focused mostly on external beam delivery and QA. Over the last 3 years, more than 20 manuscripts have been published to peer-reviewed journals and more than 100 presentations at international conferences have been submitted and presented. The topics of these publications are on new technologies at CTRC, patient specific IMRT QA, radiobiogical modeling and analysis and patient safety. Research topics that I am currently working on include: a) new technology for patient specific IMRT QA, b)new methods for pediatric radiation therapy delivery, c)advanced treatment deliveries (SRS, SBRT) incorporating imaging and/or respiratory gating and d) adaptive radiothe
