Tomotherapy

Tomotherapy is a type of radiation therapy to kill tumour cells in the body and is a treatment method for tumours. This therapy damages the cancer cell's DNA and prevents cancer cells from further division and growth. It is an advanced radiation therapy used to treat cancerous and noncancerous tumours.

Tomotherapy, also known as helical tomotherapy, is intensity-modulated radiation therapy (IMRT). The therapy is commonly used to treat prostate, brain, lung, breast, head, and neck cancers. Combined with CT scanning, it is an advanced technology that gives accurate and precise treatment, using powerful radiation beams to treat inoperable tumours.

In tomotherapy, radiation beams are aimed at the tumour from multiple directions. The treatment uses a CT scanner that rotates in a spiral pattern around the patient. Before the treatment, 3D images of the tumour are taken, which helps the doctor examine the tumour's size and spread. This process helps the doctor analyse the right intensity of radiation to kill the tumour cells without causing much damage to nearby tissue.

The primary goal of the treatment is to target the tumour cells and to control and limit the side effects and damage to nearby tissue.
