Radiation therapy (also known as radiotherapy, x-ray therapy, or irradiation) is the treatment of disease (or tumours) using penetrating beams of high-energy particles called radiation. Radiation beams must be precisely located in order to radiate the tumour without harming healthy surrounding tissue. The natural movement of organs, the bladder for example, within the body between the radiation therapy planning and treatment can make it difficult to accurately target tumours for the correct placement of radiation therapy.
Integrating the Polaris Spectra™ with an imaging device (for example, an ultrasound) that is used prior to (or during) radiation therapy treatment would allow radiation beams to be more precisely aimed at the time of treatment. This would ensure that tumours are more accurately targeted and radiation damage to surrounding tissue is significantly minimized each time treatment is given. How would Polaris Spectra integration achieve these improvements to the procedure? Using a specially marked imaging device, for example an ultrasound probe, to locate the tumour would allow the ultrasound probe to be tracked by the Polaris Spectra Position Sensor, resulting in the ability to identify the exact location and orientation of the ultrasound probe. With the exact location of the probe being known, once the tumour is located, the radiation beam and probe location can be aligned and, as a result, the accuracy of the treatment is vastly improved.
