Proton Beam Therapy
Proton beam therapy utilizes proton beams that deliver their maximum effect at a specific depth before stopping. By adjusting the energy of the proton beam, this stopping position can be precisely controlled. Aligning this peak with the cancer’s location minimizes the dose to surrounding normal tissue. This allows for a high dose of radiation to be delivered to the cancer, aiming for its eradication, while carefully adjusting to avoid side effects in normal tissue. Proton beams are an ideal form of radiation, providing a high dose to the cancer while sparing the surrounding normal tissue.
TomoTherapy
The TomoTherapy delivers radiation precisely according to the shape of the tumor. Utilizing Intensity Modulated Radiation Therapy (IMRT), the shape and intensity of the radiation are adjusted in complex ways through computer control, allowing for 360-degree irradiation. This technique concentrates a large amount of radiation on the tumor while minimizing exposure to surrounding healthy organs. As a result, the effectiveness of the radiation therapy on the tumor is increased, and side effects are reduced.
Brachytherapy (RALS)
RALS is a type of radiation therapy for malignant tumors. By delivering radiation very close to the tumor, it is possible to administer a high dose, effectively killing the tumor cells. Since the radiation does not spread far, the exposure to surrounding healthy tissue is minimized, reducing side effects.
