JW Medical 'Aloka Arietta850'

With the strengthening of health insurance coverage policies increasing the demand for imaging diagnostics that can anticipate various diseases, JW Medical's ultrasound diagnostic devices are gaining attention. They are praised for enabling fast and accurate diagnosis across various fields including radiology, obstetrics and gynecology, internal medicine, and surgery.

JW Medical is leading the localization of medical devices in a market previously dominated by imported products such as LED shadowless lamps and digital X-rays. In 2016, the company established its business infrastructure by exclusively supplying various ultrasound diagnostic devices, including the Arietta series from Japan's Hitachi, to the domestic market. In 2018, JW Medical officially entered the market with the launch of the new product Aloka Arietta850. This product applies Hitachi's world-first micro-machined ultrasound semiconductor transducer and OLED monitor.

The newly developed transducer uses 100% semiconductor materials instead of the conventional crystal method, allowing one transducer to utilize multiple broadband frequencies, which offers the advantage of examining various body parts. It is an improved version of the core technology owned by Hitachi, enabling detailed measurement of the stiffness of areas suspected of cancer through ultrasound signals. This technology displays hard cancerous tumors and soft normal tissues in different colors, making it easy to identify the malignancy of tumors. While expressing tissue elasticity in colors, it simultaneously quantifies lesion stiffness using frequency, significantly enhancing accuracy.
