elekta

Elekta AB (publ) is a Swedish multinational medical device company that develops and sells equipment and software for radiotherapy and radiosurgery. Headquartered in Stockholm, it serves hospitals and cancer centers worldwide, focusing on non-invasive treatments that use precision radiation therapy and neurosurgical applications.

Origins trace to the work of Lars Leksell, with the Leksell stereotactic frame and the Gamma Knife, which became a flagship radiosurgery platform as the company expanded its radiotherapy portfolio. Elekta’s product range covers Gamma Knife radiosurgery systems, linear accelerators for external beam radiotherapy, and image-guided radiotherapy platforms. The company’s Unity MR-Linac combines Elekta’s linear accelerator with a high-field 1.5-tesla MRI system supplied by Philips, enabling real-time imaging to guide treatments.

Elekta also develops software to support planning, delivery, and data management, including the Monaco treatment planning system and the Mosaiq oncology information system, which facilitate workflow in radiotherapy departments from planning to patient data management and treatment delivery.

With a global footprint, Elekta operates through regional offices, service networks, and manufacturing sites and markets its products and services to healthcare providers worldwide. The company is publicly listed on Nasdaq Stockholm and maintains research and development activities across its international operations.
