The latest in radiotherapy technology, this “image-guided radiotherapy” improves the accuracy of treatment and limits exposure to healthy tissues. Since tumours vary in size, location and their proximity to sensitive organs, tomotherapy offers a clear advantage when treating certain cancers and considerably improves the quality of patient care.
“We are very proud to have this new machine,” said Dr. Carolyn Freeman, MUHC Director of Radiation Oncology. “As a university health care centre, we are continuing our mandate by remaining on the cutting edge of technology and forging ahead in the fields of research and education.”
Tomotherapy is a new type of X-ray technology. It combines an intensity-modulated radiotherapy device with a scanner that detects the morphology of internal organs. The device travels around a patient lying down on a treatment table and delivers image-guided radiotherapy. This major technological innovation facilitates treatment through the delivery of intensity-modulated beams in three-dimensional space. “By combining an accelerator—which moves around and along the patient—with a scanner, this method provides continuous treatment no matter where the disease is located and follows the cancer’s progression over time,” stated Dr. Freeman.
Three-dimensional images precisely define tumour contours. These images allow doctors to adjust the size, shape and intensity of the beams in relation to the tumour’s unique characteristics, thus limiting the exposure of healthy tissue to radiation. If required, the scanner can also verify the location of the tumour before each treatment so that the patient’s treatment plan can be modified accordingly. A tumour can indeed move a few millimetres from one session to the next. “The advantage of this new technology for patients is that it improves the quality of care and treatment,” added Dr. Freeman.
About the McGill University Health Centre
The McGill University Health Centre (MUHC) is a comprehensive academic health institution with an international reputation for excellence in clinical programs, research and teaching. The MUHC is a merger of five teaching hospitals affiliated with the Faculty of Medicine at McGill University — the Montreal Children's, Montreal General, Royal Victoria, and Montreal Neurological hospitals, as well as the Montreal Chest Institute. Building on the tradition of medical leadership of the founding hospitals, the goal of the MUHC is to provide patient care based on the most advanced knowledge in the health care field, and to contribute to the development of new knowledge.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
