Dorayshield's high-end tungsten alloy collimators have been successfully exported to South Africa, contributing to the development of nuclear medicine in Africa.

Introduction: Dorayshield, a high-end radiation protection brand, recently announced the successful shipment of its first batch of customized tungsten alloy collimators to Johannesburg, South Africa. The shipment, valued at approximately $200,000 USD, marks a substantial breakthrough in the company's African market strategy and provides local radiotherapy centers with a more precise beam control solution.

The collimators exported this time are CNC-machined from a heavy tungsten alloy (density ≥ 17.8 g/cm³), with internal surfaces polished to Ra 0.4 μm, ensuring a beam penumbra of less than 1 mm. The multi-leaf design allows for interleaf spacing of ≤ 50 μm, enabling 0.5 mm field width adjustment, meeting the stringent requirements of intensity-modulated radiotherapy (IMRT) and stereotactic body radiation therapy (SBRT). The products comply with IEC 60601-2-1 and South African NRCS certification, and come with a third-party shielding effectiveness report. They attenuate 6 MV X-rays by over 95%, significantly reducing leakage dose from the handpiece.

To meet customer delivery deadlines, Dorayshield operated a 24/7 production line, processing, cleaning, and vacuum-sealing 128 collimators within two weeks. The collimators were then shipped in an incubator and are expected to arrive at Cape Town International Airport within five working days. The purchaser said the new equipment will be deployed in its newly built center, providing more precise radiotherapy services to more than 1,200 cancer patients each year.
