Elekta has received clearance to CE mark its Agility multileaf collimator (MLC), a beam-shaping device integrated into the head of a linear accelerator (linac) for treating cancer.

Agility features include 160 5mm-thin tungsten leaves with a leaf speed of up to 6.5cm a second, and Integrity R3.0 software, the company’s seventh generation digital control system to precisely coordinate leaf movements with variable dose delivery rates and other treatment parameters.

The device enables clinicians to enhance treatment times for patients, while delivering radiation doses to the contours of tumours with extreme precision.

Elekta president and CEO Tomas Puusepp said to meet the increasing need for cancer treatment, the company has collaborated with hospitals and research institutions to develop a solution that can increase the throughput of patients while delivering outstanding precision.

"Modern cancer treatment is very complex and will continue to be even more so. It’s vital to be able to shape a radiation beam with high precision to avoid harming surrounding tissue, while maintaining time efficiency. Agility is designed to meet these demands. When it reaches the market, hundreds of thousands of patients will benefit from this unique device every year," Puusepp added.

St. James’s University Hospital, UK, radiotherapy physics head Vivian Cosgrove said for patients, use of Agility with volumetric modulated arc therapy (VMAT) delivery will allow the hospital to administer stereotactic body radiation therapy (SBRT) quickly and efficiently than the current fixed-field approach.

"The advantages with Agility will work in harmony with other technological developments today and in the future," Cosgrove added.

Agility is not yet available for sale or distribution in any market, the company said. Elekta is a human care company that develops tools and treatment planning systems for radiation therapy, radiosurgery and brachytherapy, as well as workflow enhancing software systems across the spectrum of cancer care.
