Revised mask-wearing requirements at our Medical Centre and Hospital

Radiation Oncology Suite

Our Radiotherapy Oncology Suite is a modern facility for External Beam Radiation Therapy and Brachytherapy. Equipped with the Elekta VersaHD using advanced flattening filter-free technology, we aim to provide swift and safe radiation treatment for our patients. Complemented with 4D Computed Tomography Simulation capability and an innovative Qualitative Assurance system, enhanced precision of tumor treatment and greater sparing of normal tissues to minimize side effects combine to ensure the quality of care delivered.

Intensity Modulated Radiotherapy (IMRT)
IMRT is a form of radiation technique with selective dose pattern that conforms more precisely to tumour while reducing radiation exposure and damage to healthy tissues near the tumour site. In head and neck cancers, IMRT helps to minimise side effects such as dry mouth and loss of appetite when radiation exposure to salivary glands is minimised while in prostate cancer, higher radiation dose can be delivered to tumour with acceptable risk of side effects to the rectum and bladder.1

Image Guided Radiotherapy (IGRT)
IGRT has the advantage of monitoring changes in tumor size and location during radiation treatment with the use of imaging modalities like Cone-beam Computed Tomography and Ultrasound. This enhances accuracy in the treatment position and allows for fine-tuning of radiation dose and technique when necessary.  

Volumetric Arc Therapy (VMAT)
VMAT delivers radiation continuously while the treatment gantry rotates around the patient. The advantage is more conformal radiation treatment delivery in a shorter time, from between five and ten minutes to 1 and 1.5 minutes (single arc treatment)2 with increased accuracy, speed and comfort. The aperture of the multi-leaf collimator, dose rate and rotation speed can be varied to suit the different levels of treatment intensity required of the tumor site. 

Stereotactic Radiosurgery (SRS) and Radiotherapy (SRT)
SRS and SRT involve treating small tumors using several radiation beams targeted at the tumor from different directions delivering a high dose with uncompromised precision. Thus, the treatment requires the patient to remain still and  immobilization aids such as head frame or mask (in head and neck cancers) may be  used.  SRS and SRT usually involve single or fewer sessions of treatment and are particularly suited for tumors in the brain3, lung, liver and spine.

High Dose Rate 3D Brachytherapy (HDR3DBT)
This treatment method involves the temporary placement of tiny radiation sources very near to the tumor to allow a high dose of radiation to be delivered safely right at the tumour site while minimizing exposure to surrounding healthy tissues. Gynecology cancers4 and prostate cancers are tumors most commonly treated by HDR3DBT.
