High-precision radiation therapy system (linac)

High-precision radiation therapy system (linac)

Intensity-modulated radiation therapy (IMRT) and image-guided radiation therapy (IGRT)

The newly introduced linear accelerator will enable patient-friendly, high-precision radiation therapy by concentrating radiation on cancerous lesions and reducing the dose to normal tissue.
This device is compatible with high-precision radiation therapy, including Intensity Modulated Radiation Therapy (IMRT), Volumetric Modulated Arc Therapy (VMAT), and Image-guided radiotherapy (IGRT).It also enables irradiation at a higher dose rate than conventional devices, enabling radiation therapy in a shorter time.

Optical Patient Positioning System

A high-resolution camera is used to scan the patient's skin surface, allowing for three-dimensional alignment with an accuracy of less than 1 mm.

Since no X-rays are used to confirm positioning, patient setup can be performed without exposure to radiation. When combined with this device, patient movements can be monitored without exposure to radiation during irradiation, and irradiation can be automatically paused if patient movements exceed the acceptable range and resumed when they return to the acceptable range.
This allows for gentler treatment for patients, reducing skin marks and radiation exposure.

Motion Tracking System

It is equipped with a real-time tumor tracking system and a system to support image-guided radiation therapy (IGRT).

The motion tracking system function involves placing a metal marker near the lesion in advance, and then identifying the location of the lesion by checking the marker in real time using X-ray fluoroscopy, enabling dynamic tracking intercept irradiation, which only irradiates when the metal marker reaches a specific position.
It is used to treat cancers that move due to respiratory movements (such as lung cancer and liver cancer).

The image-guided radiation therapy (IGRT) function supports high-precision radiation therapy by using X-ray fluoroscopy and CT images to set up the patient, rather than traditionally using skin marks for positioning.
