Hong Kong Sanatorium & Hospital selects RayStation

RaySearch Laboratories AB (publ) announces that Hong Kong Sanatorium & Hospital has placed an order for RayStation®* as treatment planning system for its proton therapy center.

RaySearch has a strong position in the radiation therapy market in Hong Kong. With the new RayStation order from Hong Kong Sanatorium & Hospital, it is further strengthened and the market share is now around 30 percent.

The proton therapy center at Hong Kong Sanatorium & Hospital installs the Hitachi PROBEAT-V proton therapy system. The RaySearch software selected by the center includes advanced technologies such as IMPT (intensity modulated proton therapy), multi-criteria optimization, and full adaptive planning capabilities, along with conventional photon IMRT/VMAT planning (intensity modulated radiation therapy and volumetric modulated arc therapy) and planning for the Radixact system from Accuray.

George Chiu, Head of Department of Radiotherapy, Hong Kong Sanatorium & Hospital, says: “We have been searching for the best planning system for our proton facility, finally we found that RayStation could provide the best flexibility and synergy in our setting with all different machines, like CyberKnife, Radixact and Versa HD. Their AI feature is also impressive and will help a lot in our future development.”

Johan Löf, founder and CEO, RaySearch, says: “We are happy to welcome Hong Kong Sanatorium & Hospital as our first customer in Hong Kong within the proton therapy segment and look forward to a rewarding collaboration and the opportunity to contribute to improved care for the hospital’s patients.”
