Harvard Cyclotron Laboratory
The Harvard Cyclotron Laboratory operated from 1949 to 2002. It was most notable for its contributions to the development of proton therapy. The Harvard Cyclotron Laboratory was built with office of Naval Research funds between 1946 and 1949 to replace an earlier, lower energy, cyclotron that was sent to Los Alamos for use in the Manhattan Project. Richard Wilson, "A Brief History of the Harvard University Cyclotrons", Harvard University Press, 2004 Until 1961, the laboratory primarily performed experiments in physics. The lab performed research and development in particle physics (including ''particle detectors'' development and testing), activation analysis, radiobiology, and solid state physics. The use of proton particle accelerators for external beam radiotherapy was largely developed at this facility in collaboration with Massachusetts General Hospital. From 1961 to its closing, the laboratory provided proton therapy to over 9,000 patients. After 1974, "almost 3,000" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

External Beam Radiotherapy
External beam radiotherapy (EBRT) is the most common form of radiotherapy (radiation therapy). The patient sits or lies on a couch and an external source of ionizing radiation is pointed at a particular part of the body. In contrast to brachytherapy (sealed source radiotherapy) and unsealed source radiotherapy, in which the radiation source is inside the body, external beam radiotherapy directs the radiation at the tumour from outside the body. Orthovoltage ("superficial") X-rays are used for treating skin cancer and superficial structures. Megavoltage X-rays are used to treat deep-seated tumours (e.g. bladder, bowel, prostate, lung, or brain), whereas megavoltage electron beams are typically used to treat superficial lesions extending to a depth of approximately 5 cm (increasing beam energy corresponds to greater penetration). X-rays and electron beams are by far the most widely used sources for external beam radiotherapy. A small number of centers operate experimental and pi ...

1949 Establishments In Massachusetts
Events January * January 1 – A United Nations-sponsored ceasefire brings an end to the Indo-Pakistani War of 1947. The war results in a stalemate and the division of Kashmir, which still continues as of 2022. * January 2 – Luis Muñoz Marín becomes the first democratically elected Governor of Puerto Rico. * January 11 – The first "networked" television broadcasts take place, as KDKA-TV in Pittsburgh, Pennsylvania goes on the air, connecting east coast and mid-west programming in the United States. * January 16 – Şemsettin Günaltay forms the new government of Turkey. It is the 18th government, last single party government of the Republican People's Party. * January 17 – The first VW Type 1 to arrive in the United States, a 1948 model, is brought to New York by Dutch businessman Ben Pon. Unable to interest dealers or importers in the Volkswagen, Pon sells the sample car to pay his travel expenses. Only two 1949 models are sold in America that ...
