These include: radiosurgery (1988), hyperthermia, 3D planning, isotopic immunotherapy, intraoperative radiotherapy (IORT) and 3DCRT.

is underway at Mount Zion.
UCSF becomes active in the Radiation Therapy Oncology Group and begins a sensitizer research program. The Northern California Cancer Program is begun along with the Northern California Oncology Group. Headed by Dr. Steve Carter, UCSF
Radiation Oncology is an active leader in this organization.
UCSF Radiation Oncology becomes a Division of Radiology with a separate hospital budget.
Lawrence Berkeley National Laboratory asks UCSF to become involved in heavy particle research using helium ions. After biology and physics research and development, the treatment of ocular melanoma begins in 1977.
Dr. Jerry Vaeth leaves UCSF Mount Zion and the hospital asks Dean Krevans for help. He requests the Radiation Oncology section to staff Mount Zion. This is accomplished, and the Tricenter is born. Equipment includes a betatron with
electrons. Joe Castro becomes chief. For several years the residency program there remains separate. Radiobiology labs are located at Mount Zion.
Franklin Hospital (Ralph K. Davies) asks Radiation Oncology at UCSF to staff their new Radiation Oncology unit with a cobalt and a 4 MeV Linac. It becomes an integral part of the department, including residents.

Dr. Buschke retires as chief of therapy and Dr. Ted Phillips is made chief.

The 1 MeV machine is replaced by a Clinac 4, #007, licensed to cure. With RMP funding, the Moffitt department is enlarged into nuclear medicine space; nuclear medicine is moved elsewhere. Soon afterward, a simulator is installed.
Custom block cutting is introduced.
Ted Phillips spends a 6 month sabbatical at Stanford.
The first treatment planning computer is installed at UCSF and Vernon Smith begins to develop and improve it.
Dr. Jerry Vaeth leaves to start the Tumor Institute at Mount Zion. Dr. Ted Phillips is recruited to replace him. Phillips had been researching radiobiology in the Navy at Hunter’s Point.
Dr. Ted Purcell and Dr. Ted Phillips, the first clinicians dedicated exclusively to Radiation Oncology at UCSF, finish their training.

Dr. Stone retires and Alex Margulis is recruited to Chair Radiology.

The synchrotron project is completed. Results are similar to those with 22 MeV betatrons and the 70 kVp is deemed too expensive to justify. The facility is converted to the Laboratory of Radiobiology and Dr. Harvey Patt, Dr. Sheldon
Wolff and Dr. James Cleaver recruited to staff it.
The 400 kVp machine is replaced by a rotational Theratron F cobalt machine.

Dr. J. Franz Buschke is recruited from the Swedish Hospital in Seattle to head the therapy section at UCSF. He had pioneered supervoltage radiotherapy after joining the Swedish Hospital.
Previously he had trained in Germany and France and worked with Del Regato and Cantril. He joined UCSF with Glenn Sheline and Jerry Vaeth; the three making up the radiatoin therapy faculty in 1960. In 1960 the first trainee dedicated
exclusively to radiation therapy begins work at UCSF.

The Radiology department moves from the old UC hospital to UCSF Moffitt Hospital, third floor. The therapy unit has a 1 million volt GE resonant transformer and a 400 and a 250 kVp x-ray machine. This same year, Dr. Low-Beer dies of
Dr. Stone returns, and in a Janeway lecture describes the serious complications seen with neutron therapy. Based on this, he concludes that very low LET would be better and secures funding from the AEC to build a 70 MeV electron
synchrotron. This is built by GE and begins to treat patients in 1955. As part of the project he hires three physicists; Gail Adams, Garret Holt and Mary Lou Merck, who also staff the therapy section. Radiobiology is staffed by Dr. Henry
Kohn and Dr. Bob Kallman among others.
The cyclotron is used for Manhattan project work and Dr. Stone becomes head of the radiation safety aspects of the Manhattan Project. Many UCSF faculty leave to serve in the armed forces.
B.V.A. Low-Beer, a Czech radiologist, is recruited to head the therapy section. in Radiology. He is interested in radioisotope therapy, as he came from the Crocker Lab at Berkeley where he worked on isotopes. He is also interested
in Head and Neck therapy.
Dr. Stone begins to work with Dr. John Lawrence on the use of neutron beams created in the 30 inch cyclotron to treat cancer. After 35 patients the project is switched to the 60 inch cyclotron and a total of 250 patients are treated,
ending in 1942.
Dr. Stone works with the Lawrence brothers and other physicists to design and build an 800 kVp x-ray machine at the Crocker Lab in Berkeley and install it in the Radiology Department in the old UC Hospital at UCSF. It is one of the first
megavoltage units in the United States. Equipment at that time consists of this machine, a 200 kVp machine and radium.

Dr. Robert Stone, MD is recruited to head the new Division of Radiology in the Surgery Department at UCSF. He was trained in Canada and had an interest in therapy and diagnostics.

As the former chair of radiology at the San Francisco Medical School , he served on the Manhattan Project throughout the war years and was well-placed to direct research funding from the Atomic Energy Commission (AEC) to the San
Francisco campus after the war. Radiology research at San Francisco grew out of the earlier work in medical physics done with cyclotron-produced isotopes before the war. In 1949, under contract with the AEC, a Radiological Laboratory
was established to allow Dr. Stone to investigate the effects of supervoltage radiation therapy for cancer. Funded by an annual contract with the AEC, a seventy million-volt synchrotron was installed at UCSF Parnassus and the
radiological laboratory combined physics, biology, and clinical radiology to study the general effects of radiation. In 1951, a Radioactivity Research Center was founded for supervision of the radioisotopes used for medical research at San
Francisco, funded with a combination of University, American Cancer Society, Atomic Energy Commission, and NIH money.
