Constructed in 1992 and finished in 1998, the HRH Princess Maha Chakri Sirindhorn Medical Center opened its doors officially in 2000, with HRH Princess Sirindhorn herself conducted the opening ceremony on November 2nd, 2000.

The hospital’s main aim is to serve as the major teaching hospital for both the Faculty of Medicine and other health science-related faculties of Srinakharinwirot University. It is one of two teaching hospitals of Srinakharinwirot University, the other being Panyananthaphikkhu Chonprathan Medical Center in Nonthaburi Province.

The hospital consists of 378 beds, with a total area of 58,595 square meters. As of 2019, the hospital has 11 medical specialty departments.

This is also the first hospital in Southeast Asia to treat patients with its new Varian ProBeam® proton therapy system, especially to target a complicated abdominal cancer using carefully shaped high-definition pencil beam scanning.

The Varian ProBeam uses sophisticated imaging to see, adapt, and deliver treatment to the designated site, using a powerful particle accelerator called the Superconducting Cyclotron. Protons are accelerated to about two-thirds the speed of light, or more than 160,000 km per second, to destroy cancer cells.

The beam transport system shapes and guides the small beam size necessary for intensity-modulated proton therapy (IMPT). This enables clinicians to target very small areas and minimize exposure to nearby healthy tissues, which is advantageous for treating tumors where vital structures are closer together.

The compact single-room system is equipped with a 360-degree rotating gantry, providing the freedom to image and treat the patient from any angle without repositioning.
