Shantou Institute of Ultrasonic Instruments

What Shantou Institute of Ultrasonic Instruments does

Shantou Institute of Ultrasonic Instruments (SIUI), founded in 1963 in Shantou, Guangdong, China, is a privately held dual-division medical imaging and industrial non-destructive testing (NDT) equipment manufacturer employing 501-1,000 people. The Medical Imaging division produces the Apogee series of color Doppler ultrasound systems (spanning 15+ models from entry-level to expert-class), the CTS series of black-and-white ultrasound, dedicated veterinary ultrasound systems, the IBUS 60/70 automated breast ultrasound scanner, and an Integrated Portable DR (digital radiography) line launched in 2017-2019 with four use-case variants. The NDT division manufactures the SUPOR and SyncScan/SyncScan 2 phased array ultrasonic flaw detectors, thickness gauges, ultrasonic crawlers for pipe inspection, and a comprehensive range of probes and calibration blocks, and operates the affiliated unit of the China Machinery Industry Ultrasonic Instrument Product Quality Supervision and Testing Center.

SIUI's underlying technology rests on proprietary imaging platforms such as RealView/RealView+ (described as a Sino-American joint R&D breakthrough in front-end image processing), Tuned Gain (claimed +40% image resolution), Tailored Filter (claimed +35% S/N ratio), Tactile Flow for low-velocity blood-flow detection, Talented Encode, Crystal Purity single-crystal transducers, Contrast Imaging, Elastography, and simultaneous PA+TOFD inspection. The ULTRACLOUD platform (cloud.siui.com) and the Mai Li Yi Sheng (麦粒医生) mobile app add cloud diagnosis, maintenance, training, and remote-education services around the hardware install base.

The company generates revenue primarily through direct enterprise hardware sales (medical imaging systems, portable DR, and NDT instruments) supplemented by professional engineering and clinical-application services, cloud-services subscriptions, and a recurring-service layer via ULTRACLOUD. Go-to-market relies on direct enterprise field sales, multi-language websites in English, Chinese, Russian, and Spanish, and recurring international trade-show participation (MEDICA, FIME, ECR), serving hospitals, clinics, veterinary practices, and industrial customers across petrochemical, aerospace, shipping, machinery/metallurgy, transportation, and mega-project infrastructure markets.
