Radiation Oncology/IMRT/IMRT Overview
|
This section is about how intensity-modulated radiation therapy (IMRT) works (in brief) and the history of IMRT. More technical aspects of IMRT should be placed in the section Radiation Oncology:IMRT Technical. Clinical results of IMRT should be placed elsewhere.
History[edit | edit source]
Timeline of IMRT[edit | edit source]
- 1992 - 1994 - proprietary IMRT development at NOMOS (initially named VISUS Medical Devices, then Cognos*centi, then NOMOS)
- 1994 - NOMOS PEACOCK system (first patient treated in 1994 at The Methodist Hospital, Houston, TX, USA)
- 1996 - First IMRT treatment with a conventional linac equipped with a multileaf collimator (MLC)
NOMOS PEACOCK[edit | edit source]
The introduction of a commercial IMRT system into popular use began with the PEACOCK system produced by the NOMOS Corporation (Pennsylvania, USA). The PEACOCK system consists of the MIMiC, which is a "bolt-on" multileaf collimator, and a dedicated treatment planning system. Treatment with the PEACOCK is described as "serial tomotherapy" in which the treatment is delivered using non-overlapping arcs (thus "tomo" or slice therapy) with couch movement occurring between each arc (thus "serial").
