    Dr. Todd Atwood is an Associate Professor and Senior Associate Division Director of Transformational Clinical Physics. He is also the Technology Section Chief for the Benign service, which includes our evolving program in Noninvasive Cardiac Radioablation. Dr. Atwood's clinical focus is on external beam radiation therapy workflow development, stereotactic body radiation therapy techniques, and respiratory motion management.

    In addition to his clinical responsibilities, Dr. Atwood is spearheading our program to transform the role of the clinical medical physicist. An important component of this program is the Physics Direct Patient Care Initiative (PDPCI), whereby medical physicists establish independent professional relationships with patients to facilitate more impactful innovations and initiate new clinical collaborations with radiation oncologists. He is the Principal Investigator of a phase II and a phase III randomized clinical trial evaluating the impact of physics direct patient care on patient experience and operational efficiency.

    Dr. Atwood is also dedicated to service and education on both the national and international level. He is the Chair of the Smart Practice Subcommittee of the American Association of Physicists in Medicine (AAPM) Medical Physics 3.0 Committee and is the co-creator of the Varian Advanced Radiotherapy Clinical School and the UC San Diego Patient Communication for Medical Physicists Workshop.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
