Gachon University Gil Hospital introduces the first 'Markeris' radiation therapy technology in Incheon

Aug 29, 2024

Gachon University Gil Hospital (Hospital Director Kim Woo-kyung) introduced a marker-less radiation therapy aid to the entire treatment room of the Department of Radiation Oncology for the first time in Incheon.

For radiation treatment of cancer patients, the treatment aiming line (marker) is displayed on the patient's skin using human ink, and the marker must be maintained until the end of radiation treatment to maintain the same posture and position during treatment.

Cancer patients who usually need to be treated repeatedly every day over four to six weeks are restricted from bathing and showering to maintain markers. As a result, not only is it hygienic and cosmetic inconvenience, but there are cases where you feel anxiety beyond discomfort, especially in hot and humid summer months.

Gachon University Gil Hospital has introduced a radiation therapy aid called AlignRT (AlignRT), which does not mark the patient's body, and is applying it to all carcinomas except head and neck cancer and brain tumors that wear masks on their heads.

The alignment RT introduced by Gachon University Gil Hospital is an unmarked Surface Guided Radiation Therapy, which allows equipment to accurately perform radiation therapy without markers by recognizing and matching the body surface of the patient's treatment area during radiation therapy.

To this end, three cameras installed on the ceiling will construct a three-dimensional image using light reflected from the patient's surface, and advanced technology will be applied to identify the treatment site.

Sung Ki-hoon, director of the Department of Radiation Oncology at Gachon University Gil Hospital, said "This technology can check the patient's posture up to 0.1mm, enabling accurate treatment, replacing the repeated X-ray image guidance for treatment, reducing radiation exposure, and maintaining daily life without discomfort caused by 'marker' during the treatment period, so patients are highly satisfied with treatment."

Gachon University Gil Hospital is maximizing radiation therapy synergy with the operation of state-of-the-art cancer treatment devices 'Helsion' and 'AlineRT' introduced in October last year. Helcion is a intensity-controlled radiation therapy device based on real-time image induction. It has the advantage of drastically reducing the treatment time of patients with a treatment machine rotation speed four times faster than conventional radiation therapy and a multi-leaf collimator speed twice faster.

Gachon University Gil Hospital applies Helcion to most tumor treatments such as prostate cancer, lung cancer, cholangiopancreatic cancer, head and neck cancer, rectal cancer, and metastatic cancer.

The Markeris Radiotherapy Center at Gachon University Gil Hospital operates not only Helcion, but also radiation therapy devices such as RappidArc and ClinaciX, creating synergy with Markeris aids.

Kim Woo-kyung, head of Gachon University Gil Hospital, said "With the introduction of advanced radiation therapy devices and surface-guided treatment aids, Gachon University Gil Hospital will provide radiation treatment patients with the best treatment results and services to minimize discomfort in their daily lives."
