An important member of the medical physics community, Arnold Feldman, PhD, passed away on January 23, 2009. Dr. Feldman was a charter and active member of AAPM for his entire career. His career spans decades and many contributions, even working on the Manhattan Project in the 1940s. He was well-liked by those who knew him and worked with him. Our sincerest condolences to his family, friends and colleagues. From the Intermountain Jewish News:

Medical physicist Arnold Feldman of Peoria, Ill., formerly of Denver, passed away Jan. 23, 2009.

A memorial service is scheduled April 5, 2009, at Congregation Anshei Emeth in Peoria.

“He was a very kind man with strong opinions,” the family said. “He loved to discuss anything with anyone, but he especially loved politics.”

Dr. Feldman was born April 12, 1924 in Allentown, Pa. After graduating high school at 16, he attended Pennsylvania State University where he earned a BS in physics by the age of 19.

Dr. Feldman, who joined the US Army in 1944, was assigned to the Manhattan Project, which developed the first atomic bombs. He first worked at the New Yew York project site and then at Los Alamos, NM.

After the war he moved to Pasadena, Calif., with his wife Adele, whom he married on March 25, 1945.

Dr. Feldman earned an MS from Cal Tech in 1948 and then trained in medical physics at the Mayo Clinic.

In 1951, he took a position in the radiology department at the CU School of Medicine in Denver, where he also received his doctorate.

From 1962-1963, Dr. Feldman was a fellow in the radiotherapy department at Churchill Hospital in Oxford, England.

He spent the following year in Denver and then accepted a position in the biophysics department at the Mayo Clinic.

In 1968, he joined the biophysics department at the Washington University School of Medicine in St. Louis.

Following his divorce from Adele, he married his second wife Sybil Quinlan Hesh. In 1973, the couple moved to Peoria, where Dr. Feldman worked in radiation physics.

He retired at age 75.

Dr. Feldman was a founding member of the American Association of Physicists in Medicine. He also received the organization’s first Physics Achievement Award.

He was a past president of the Peoria chapter of the ACLU and belonged to Optimists, Common Place and the Sun Foundation. An activist with the Democratic Party, he also enjoyed tutoring for adult literacy projects.

Dr. Feldman is survived by his wife Sybil Hesh of Peoria; children Ethan (Nancy) Feldman of Colorado, Lou Anne Davidson, Tracey (Bill) Lance and Tim Hesh, all of Illinois; and grandchildren Tyler (Donna) Hesh, Sarah Feldman, Michael Feldman, Christopher Hesh and Laura Hesh.

He was predeceased by his daughter Helen.

World Congress 2009 Medical Physics Conference

March 15, 2009 · Posted in Conferences / Meetings · Comment 

The World Congress on Medical Physics and Biomedical Engineering will be held September 7-12, 2009 in Munich, Germany this year. The meeting is held every three years and organized by the IUPESM (International Union for Physical and Engineering Sciences in Medicine) and is expected to draw more than 4000 visitors this year. The theme of this year’s meeting is “For the Benefit of the Patient.” 

While the meeting was announced a while ago, the deadline for paper submissions to be included in the proceedings has been pushed back to April 15, 2009, so there’s still some time to get in.  Paper topics are as follows: 1. Radiation Oncology, 2 Diagnostic Imaging, 3. Radiation Protection and Dosimetry, Biological Effects of Radiation, 4. Image Processing, Biosignal Processing, Modelling and Simulation, Biomechanics, 5. Information and Communication in Medicine, Telemedicine and e-Health, 6. Surgery, Minimal Invasive Interventions, Endoscopy and Image Guided Therapy, 7. Diagnostic and Therapeutic Instrumentation, Clinical Engineering, 8. Micro- and Nanosystems in Medicine, Active Implants, Biosensors, 9. Neuroengineering, Neural Systems, Rehabilitation and Prosthetics, 10. Biomaterials, Cellular and Tissue Engineering, Artificial Organs, 11. Biomedical Engineering for Audiology, Ophthalmology, Emergency & Dental Medicine, 12. General Subjects, and 13. Special Topics and Workshops.
