Renji Hospital affiliated with Shanghai Jiao Tong University School of Medicine held the "Walking with Ren, Embracing New Students" Radiotherapy New Technology Forum and the opening ceremony of the world's first integrated CT circular linear accelerator today.

The world's first integrated circular CT linear accelerator uLinac HalosTx, independently developed by China, has been officially launched, marking a major breakthrough in the research and clinical application of high-end medical equipment in China and setting a new benchmark for the field of tumor radiotherapy in China.

Upon investigation, it was found that uLinac HalosTx was developed by United Imaging Group and is the world's first integrated CT ring linear accelerator equipment.

According to the official introduction, this device integrates 40 rows of 80 layers 87cm ultra large aperture CT and a circular accelerator, and is equipped with the industry's largest EPID tablet of 65cm × 61cm. It pioneered the "dual perception of image dose" technology, not only breaking the limit of image guidance technology, but also achieving dynamic monitoring of tumor changes and radiation dose throughout the entire course of treatment for the first time.
This device is based on a circular architecture and underlying hardware innovation, creating a "three in one" high-efficiency radiotherapy engine. The treatment efficiency is 50% higher than traditional models, effectively relieving clinical treatment pressure.

In addition, its pioneering uCT ART online adaptive radiotherapy technology can be empowered by AI to complete the entire process from CT image guidance to personalized plan formulation within 20 minutes, solving clinical problems caused by changes in patients' anatomical structures.

Ma Xiumei, Chief Physician of the Radiotherapy Department at Renji Hospital, introduced that currently, uLinac HalosTx is conducting more than ten online adaptive radiotherapy cases per day, with a total daily treatment volume of up to 70 cases, covering all body diseases; Among them, the proportion of online adaptive radiotherapy cases exceeds 20%, and the shortest treatment time per case is only 9 minutes and 13 seconds.
