The world’s first phased array computed tomography (CT) device, developed by a cutting-edge Chinese technology company, has been installed at Shanghai’s Ruijin Hospital. This advanced scanner is set to support approximately 400 clinical evaluations.
“At this point, we’re able to capture ultra-high-definition images of lung tissue,” stated the hospital’s radiology department director during the device’s commissioning ceremony. “Previously, such clarity could only be achieved through dissection.”
With this CT scan system, doctors can significantly enhance early disease detection accuracy through detailed internal images. The manufacturer anticipates that the device will receive a Class III medical device approval by the end of the year.
There has long been a demand for sophisticated medical imaging tools that offer higher clarity while minimizing radiation exposure. To illustrate, lung scans using this phased array CT can reach a resolution of 3072×3072 pixels, vastly superior to the 512×512 resolution typical of traditional CTs. This allows for a more precise view of lesions and surrounding tissues.
The technology not only improves diagnostic precision but also opens new opportunities in minimally invasive orthopedic surgeries. It can support comprehensive management of osteoporosis and other conditions, according to a leading specialist from a prominent university hospital.
The core of this innovative CT system is a “photon stream detector,” which employs a unique pulsed exposure scan method. Image reconstruction relies on powerful computing algorithms, making UHD images possible while cutting radiation doses by over 50%, explained a chief scientist from the developing firm.
This company independently designed the phased array CT scanner and produces its key parts domestically. Manufacturing these core components within China is expected to boost local supply chains, benefiting related industries.
