Ana Dieguez Awarded Hogstrom Superior Graduate Student Scholarship
海角社区鈥檚 medical physics and health physics program has announced Ana Dieguez as the second recipient of the prestigious Kenneth R. Hogstrom Superior Graduate Student Scholarship.
Established in honor of Professor Emeritus Kenneth R. Hogstrom鈥檚 outstanding research, scholarship, and mentorship of graduate students, the scholarship supports medical physics graduate students participating in clinical research on radiation oncology at .
鈥淎na caught my attention with her first communication with me as a prospective student; Ana presented herself as professional, competent, and clearly interested in medical physics,鈥� said Kenneth 鈥淜ip鈥� Matthews, associate professor and deputy program director. 鈥淲hen Ana asked me to supervise her thesis, I was impressed with how she鈥檇 pulled together multiple topics to envision an interesting research project. I also was extremely pleased when Ana was awarded the , which honors a colleague who has significantly impacted my own career.鈥�
Dieguez, a 2017 University del Valle de Guatemala alumna, describes the importance of this award as she advances her career.
"From the moment I joined 海角社区鈥檚 Medical Physics Program, I felt encouraged by the faculty to find a research interest that would represent an innovative approach into a dilemma in our field. In Fall 2019, I reached out to Dr. Kip Matthews to discuss possible research topics for my master鈥檚 thesis. Dr. Matthews had taught the Radiation Shielding class, MEDP7530, the prior semester and he presented areas where insufficient knowledge could potentially be limiting the quality of Shielding Calculations."
"When I talked to Dr. Matthews, we decided that VMAT Shielding Considerations was an area, with direct relevance to clinics similar to the Mary Bird Perkins Cancer Center. This project is an assessment of whether the VMAT delivery technique is adequately addressed by the NCRP Report 151 guidelines for design of a LINAC vault鈥檚 structural shielding. Report 151 was published before VMAT became a common treatment technique. As VMAT becomes the primary treatment approach for many types of cancer, we must be certain that existing and new treatment vaults provide suitable shielding."
"The main question of my thesis is whether the calculation methods and supporting data of Report 151 are sufficient to provide a satisfactory design for a vault dedicated to VMAT. This project will either confirm that existing Report 151 methods and data result in adequate designs or produce supplemental information by which we can be confident that new shielding designs are both safe and cost-effective."
"This topic is important to facilities such as Mary Bird Perkins Cancer Center, where appropriate radiation protection of staff and the public is crucial; importantly to me, this line of research represents what first inspired me to join the medical physics field: how to make effective and safe use of therapeutic radiation, allowing us to save lives without compromising quality. This project was envisioned by me, representing a new research direction for us, so obtaining funding was crucial. The Kenneth R. Hogstrom Superior Graduate Student Scholarship is the essential component that allows me to pursue this project as my Master鈥檚 thesis; I am grateful to Dr. Hogstrom and all those who supported the creation of this Scholarship."
