Tech Track 100

Doctors treating cancer patients with radiotherapy can target tumours with pinpoint accuracy thanks to Vision RT’s 3D imaging systems. Using a combination of cameras and algorithms, a model of the patient’s body is created that can be monitored in real time. If the patient moves even slightly during treatment, the radiotherapy beam automatically pauses, helping to prevent damage to surrounding organs and tissue. Norman Smith and Ivan Meir, both 48, founded the firm in an attic in 2001, designing every element of the system — from camera electronics to software algorithms — from scratch. Vision RT has since been granted 60 patents and has regulatory approval in 35 countries. Sales hit £32.5m last year thanks to strong growth in America, Europe and Asia-Pacific.
