Elekta was jointly founded in 1972 by the late Lars Leksell, Professor of Neurosurgery at the Karolinska Institute in Stockholm, Sweden, and his son Laurent (Larry) Leksell, in order to commercialize the development of the Leksell Stereotactic System, and Gamma Knife, which he had been researching since the late 1940s.

Since 1994, the company has been listed on the Nordic Exchange (Nasdaq Stockholm) under the ticker EKTAb. Larry Leksell became Chief Executive Officer of Elekta until 2005, and under his leadership the company expanded into a public medical technology group with more than 3,400 employees worldwide.

Elekta produces a wide range of devices used in stereotactic radiosurgery, a noninvasive procedure used to treat brain disorders such as tumors, arteriovenous malformation (AVM), and some functional diseases. These devices include:

Neurosurgery products

Neurosurgery products, such as the Leksell Stereotactic System, an arc-based stereotactic frame, based on a polar coordinate system, that is fixed to the patient's head when performing minimally invasive stereotactic neurosurgery procedures.

Leksell Gamma Knife, used to treat brain tumors by administering high intensity gamma radiation therapy in a manner that concentrates the radiation over a small volume. The original device was invented in 1967 at the Karolinska Institute in Stockholm, Sweden by Lars Leksell, Romanian-born neurosurgeon Ladislau Steiner, and radiobiologist Börje Larsson from Uppsala University, Sweden. The first Gamma Knife was brought to the United States through an arrangement between US neurosurgeon Robert Wheeler Rand and Leksell and was given to the University of California, Los Angeles (UCLA) in 1979. Today there are more than 360 Leksell Gamma Knife systems installed and used globally.

Linear accelerators

Elekta also produces linear accelerators (linacs) used for external beam radiotherapy (EBRT), the most common form of radiotherapy (radiation therapy). Some of Elekta's linacs include:
