AQURE
The AQURE medical accelerator is a mobile radiotherapy device intended for use in intraoperative radiotherapy treatment.
Intraoperative Electron Radiation Therapy (IOERT) involves irradiation of the postoperative bed after surgical removal of the cancerous tumor during the operation. IOERT treatment minimizes geographical error by directly exposing tissue to irradiation, protecting critical organs by using the limited range of the electron beam, and reducing the risk of complications and local control. According to the reports presented by ISIORT in 2015, the most frequently treated cancers using intraoperative radiotherapy were: breast cancer - 80%, rectal cancer - 8%, soft tissue sarcoma - 4%, prostate cancer - 2%, pancreas cancer - 1% and other - 5% (most cases are in the oesophagus area).
The AQURE linear accelerator created by the National Centre for Nuclear Research in cooperation with the Greater Poland Cancer Centre is a mobile and safe radiotherapeutic device which, operated by control cassette, can move and work in the operating room. The device generates ionizing radiation - electron beams with energies of 4, 6, 9 and 12 MeV, each with a dose rate of 5 and 10 Gy/min (500 MU/min and 1000 MU/min).
The AQURE accelerator is intended for use in a hard docking system, which means that the two parts of the applicator are permanently connected by a connecting element. The device can emit radiation with different therapeutic field sizes. For this purpose, replaceable, biocompatible applicators with a wide range of diameters and various bevel angles are used. The AQURE accelerator offers applicators with diameters of 40, 45, 50, 55, 60, 100 mm (with the option of adding optional 30, 35, 70, 80, 90 mm) - all in straight and oblique versions with a bevel of 15°, 30°, 45°. The electron beam emitted by AQURE is flat and symmetrical, ensuring the uniformity of the irradiation field, which is a condition for effective and safe IOERT radiotherapy. The device meets all the requirements of quality and safety standards for medical accelerators, including Medical Device Regulation (EU) 2017/745.
The device is currently undergoing the medical device certification process, which will enable it to be marketed and clinically used in oncology centers.
