Union Oncology Centre is equipped with a Varian Halcyon® radiotherapy system with the new generation dual-layer multi-leaf collimator (MLC). It achieves excellent target dose conformity with 5 cm/sec fast leaf travel speed and 100% overtravel capability. The system offers 5 mm field shaping resolution which reduces healthy tissues irradiation by intensity-modulated radiotherapy (IMRT).
In addition, its gantry rotates up to four times faster than a conventional linear accelerator, which can shorten the treatment duration while maintaining high treatment quality. Cone beam computed tomography (CBCT) imaging can be completed in approximately 15 seconds, which facilitates the use of image-guided radiation therapy (IGRT) to deliver precise treatment.
Our Varian Halcyon® radiotherapy system is located in Ladies’ Area and is designated for female breast cancer patients. It is operated by female radiation therapists to provide empathetic, comfortable and intimate care throughout treatment for our patients.
