That is the intention of all new developments in radiation treatment. By making delivery more accurate, and the regulation of the volume of radiation more precise, the adverse effects of radiation therapy can be minimised, making treatment easier on the patient.
Treatment costs will depend on the location and size of the tumour, and the duration of therapy. It is therefore difficult to compare costs of using different methods of delivering radiation to a tumour.
The TomoTherapy machine acquired is the latest TomoHDtreatment system from Accuray Inc. of USA, the global pioneerin the field of TomoTherapy.
The TomoTherapy treatment system delivers radiation therapy with a spiral delivery pattern called TomoHelical or with a discrete-angle approach known as TomoDirect. Photon radiation is produced by a linear accelerator which travels around the patient and moves in unison with a device called a multi-leaf collimator that shapes the beam. Meanwhile, the couch is also moving, guiding the patient slowly through the centre of the ring. In this way, TomoTherapy can deliver radiation to tumours in places that are difficult to access with other forms of radiation therapy.
Because the doctor uses 3D images from a combination of scanning technologies such as CT and MRI and special software to establish the precise contours for each treatment volume and any regions at risk, such as sensitive organs or structures, TomoTherapy minimises damage to surrounding tissue. As both a treatment delivery machine and a CT scanner, the TomoTherapy system allows doctors to take a CT scan just before each treatment. This is important because a patient's anatomy can change from day-to-day. Image-guided radiation therapy helps doctors make immediate adjustments to allow for tumor movement or shrinkage, weight loss and other changes.
Another benefit to patients is reduced treatment times. TomoTherapy is as painless as having a CT scan or an X-ray, and takes only a few minutes a day. It is also capable of treating multiple tumours, in multiple areas of the body, during the same treatment session.
TomoTherapy can be used to treat cancers all over the body, but is especially effective for prostate cancers, brain tumours, head and neck, pancreatic, breast, liver, anal and rectal cancers. Because of the degree of precision it offers in targeting and regulation of the amount of radiation delivered, TomoTherapy delivers accurate radiation therapy for even the smallest of tumours.
TomoTherapy is an advanced form of radiation treatment used to kill cancer cells. It is a state-of-the-art technique using sophisticated equipment that enables extremely precise targeting of tumours with an integrated, highly developed type of 3-dimensional image-guided radiation therapy.
