On-site assistance in radiotherapy physics: from treatment unit commissioning to the most advanced treatment techniques

Headshot of Ann Van Esch, founder of 7sigma.

‘We devote our energy to practical on-site assistance on one hand, and research and development on the other hand. In doing so, we hope to facilitate the spread of advanced radiotherapy treatment techniques in large university centers as well as in smaller private clinics, efficiently and securely.’


Ann Van Esch, PhD
