World Leading Radiotherapy Equipment
Guangzhou Concord Cancer Center is equipped with the globally leading Varian ProBeam proton therapy system. This system primarily consists of a superconducting cyclotron, beam transport system, 360° rotating gantry, pencil beam scanning (PBS) treatment nozzle, robotic treatment couch, cone-beam computed tomography (CBCT)/2D kV imaging system, and respiratory gating system. Our Proton Center has four proton treatment rooms, which are equipped with the latest pencil beam scanning (PBS) treatment nozzles, imaging systems, Eclipse treatment planning system and Aria oncology information system. All these ensure the safe, precise and efficient proton therapy for patients.
Intelligent Proton Therapy System: An Efficient, Precise, Adaptive, and Safe Solution for Cancer Radiotherapy
Efficient
Four treatment rooms enable high throughput, minimizing patient wait times.
Seamless integration of Eclipse & Aria systems optimizes workflow for maximum efficiency.
Adaptive
Advanced imaging systems monitor tumor changes in real time, enabling dynamic treatment adjustments.
Pencil Beam Scanning (PBS) adapts to complex target volumes for personalized precision.
Percise
PBS treatment head delivers submillimeter dose control, sparing healthy tissues.
Image-guided radiotherapy (IGRT) ensures treatment aligns precisely with the plan.
Safe
Multimodal verification systems guarantee dose accuracy, minimizing errors.
Automated quality control via Aria ensures reliable and safe treatment delivery.
Superconducting Cyclotron
The proton beam can be accelerated to 60.84% of the speed of light (180,000 km/s) within 18 microseconds, with adjustable energy ranging from 70 to 250 MeV, enabling the treatment of tumors at depths of 4 to 35 cm. The cyclotron has a maximum beam current of 800 nA and a dose rate of 2 Gy/min.
Beam Transport System and Scanning Nozzle
The Beam Transport System (BTS) delivers the proton beam to each treatment room. The pencil beam scanning nozzle precisely and uniformly irradiates the tumor with proton beams as small as 3 mm in diameter using spot scanning technology, covering a treatment field of up to 30 x 40 cm.
360° Rotating Gantry
The approximately 200-ton rotating gantry can achieve multi-angle tumor irradiation with a rotating speed of up to 3 degrees per second. It is equipped with a cone-beam computed tomography (CBCT) imaging system and a kV imaging system, enabling image-guided proton therapy. When combined with the respiratory gating system, it can accurately target moving lesions or treatment areas.
Proton System Auxiliary Technologies
The system has a comprehensive safety interlock system, a six-dimensional robotic treatment couch, a human collision warning system, and etc.
