A major emphasis on the measurement and reduction of radiation dose in CT imaging is underway throughout the field of medical physics. Activities include: image quality studies for low-dose imaging protocols; novel image reconstruction methods to provide improved image quality at low dose; patient-size-specific low-dose protocols, including pediatric imaging; new standards for dose measurement and reporting; and the development of appropriateness criteria in clinical CT utilization.

Imaging of Therapy Response

Key to understanding the nature of cancer and the effectiveness of cancer therapy is a better understanding of the biological, physiological, biochemical, and genotypic factors governing therapy response. For example, why does a certain course of radiotherapy succeed in one patient yet fail in another patient with the same stage and class of tumor? This major question is likely to form a central theme in the coming decade of cancer research, with multi-disciplinary research in medical physics shedding light on the complexities of radiation response in normal and cancerous tissue.

Patient Safety in Radiation Therapy

Cutting-edge methods and devices promise to enhance, quantify, and/or monitor the safe delivery of radiation in therapeutic medicine, with emphasis on innovative science and engineering for patient safety. The importance of such work is evident in recent accidents involving radiation in both the diagnostic and radiation therapy sectors. As an area of innovative scientific research, a considerable effort within the medical physics community is underway beyond basic quality control standards in radiation safety and training to identify new avenues for assuring patient safety.

Featured Interviews

Trends and Hot Topics in Medical Physics

Dr. Gary Ezzell, president of the American Association of Physicists in Medicine (AAPM), talks about current trends in medical physics, particularly the melding of imaging and radiation therapy to guide treatment. He also recaps some of the hot topics discussed at this year’s annual meeting in Charlotte, N.C., and AAPM’s key initiatives for the coming year.



Iterative Technique to Eliminate Artifacts from Implants

Dr. Web Stayman of Johns Hopkins University presents an overview of research he presented at the 2012 American Association of Physicists in Medicine (AAPM) annual meeting in Charlotte, N.C. It involves an iterative technique for computed tomography (CT) to better contend with implants to improve image-guided surgery or interventions. The technique takes knowledge about the components and integrates it into the reconstruction to eliminate artifacts.



A New Technique Utilizes Spectral Mammography to Measure Breast Density

Dr. Sabee Molloi from the School of Medicine at the University of California, Irvine, worked with a team on a study using spectral mammography to develop a quantitative technique to measure volumetric breast density. Their technique also enables a lower dose to be used for a screening mammogram. Two members of the team, Justin Ducote and Huanjun Ding, describe the research, which they presented at the 2012 annual meeting of the American Association of Physicists in Medicine.
