ViewRay MRIdian is state-of-the-art radiation therapy equipment developed by combining radiation therapy eqiupment and a magnetic resonance imaging (MRI) device. CNUSH became the third hospital in the country to introduce the system, following Seoul National University Hospital (SNUH) and Incheon St. Mary’s Hospital, and the first to do so outside the Gyeonggi region. ViewRay MRIdian uses the MRI device incorporated into the equipment to provide a direct view of the locations of normal organs and the tumor. MRI provides a better soft tissue contrast than computed tomography (CT), making it easier to distinguish tumors from normal organs, and results in zero radiation exposure. The equipment is especially useful in diagnosing tumors that move during breathing such as lung cancer and liver cancer and tumors that are difficult to discern from normal organs such as brain cancer, liver cancer, pancreatic cancer, prostate cancer, and cervical cancer. With ViewRay MRIdian, it has become possible to change the radiation therapy plan based on the results of an MRI scan on site, which had been impossible in the past. This raises the accuracy of the radiotherapy and reduces radiation exposure for normal organs adjacent to the tumor, thereby decreasing the chance of side effects. ViewRay MRIdian, introduced at CNUSH in September 2020, has been used 1,000 times over the course of a year until September 2021.
“Versa” in the name, “Versa HD,” means “Versatility.” It is the latest radiotherapy equipment that can be used in three-dimensional conformal radiation therapy (3D CRT), intensity-modulated radiation therapy (IMRT), stereotactic body radiation therapy (SBRT), and stereotactic radiosurgery (SRS). Versa HD has the world’s fastest and most accurate multi-leaf collimator system and has triple the radiation dose rate of existing equipment, so it can greatly reduce the amount of time it takes to carry out radiotherapy.
Siemens SOMATOM X.cite is the first equipment introduced in Korea that provides an automated AI CT scan program (myExam Companion). It is equipped with a Vectron x-ray tube and Stellar Infinity detector that have only been incorporated into high-spec models, making it possible to carry out accurate and safe examinations using significantly lower radiation doses. 1. It is a new type of AI examination technology that automatically adjusts the examination range and table using a fast 3D camera. 2. It uses low radiation doses. 3. An AI process optimized for a heart examination is used, and the X-ray is automatically adjusted while targeting the heart in the systolic or diastolic phase depending on the heart rate.
