Systems operate at McLaren Proton Therapy Center in Flint, Michigan, and at Massachusetts General Hospital. OnCo links it to proton therapy machines.","asOf":"2026-09-17","links":[{"label":"Official website","url":"https://www.protominternational.com"},{"label":"PTCOG: particle therapy facilities in operation","url":"https://www.ptcog.site/index.php/facilities-in-operation-public"}],"tags":["machines-wave"],"related":[],"cancers":[],"sections":["radiation","devices"],"technologies":["proton-therapy-systems","proton-therapy"],"targets":[],"drugs":[],"companies":[],"institutions":["mgh"],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hq":"Wakefield, MA","country":"US","companyType":"devices","website":"https://www.protominternational.com","stage":"growth","investors":[],"funding":[]},"route":"/companies/protom/","neighbours":{"section":[{"id":"devices","kind":"section","name":"Devices & Physical Therapies","route":"/fronts/devices/"},{"id":"radiation","kind":"section","name":"Radiation Therapy","route":"/fronts/radiation/"}],"technology":[{"id":"proton-therapy","kind":"technology","name":"Proton therapy","route":"/technologies/proton-therapy/"},{"id":"proton-therapy-systems","kind":"technology","name":"Proton therapy machines: cyclotrons, synchrotrons and single-room systems","route":"/technologies/proton-therapy-systems/"}],"institution":[{"id":"mgh","kind":"institution","name":"Massachusetts General Hospital Cancer Center","route":"/institutions/mgh/"}]}}
