sonoTECH was founded in 1996 as a spin-off of the complete research and development department of a company that was the only developer / manufacturer of diagnostic ultrasound imaging equipment in Germany. These ultrasound systems were distributed by a medical electronics leading company under their own brand name.

sonoTECH's Windows™ XP™ and Vista™ based LDR and HDR brachytherapy planning systems PSID™ (Permanent Seed Implant Dosimetry) and HDRplus™ / Flexiplan™ have been developed by sonoTECH and are distributed world-wide by highly regarded partner companies.
