A Powerful Tool for Tumor Screening and Radiotherapy Positioning: Aquilion Lightning Diagnostic-Grade Large-Bore Simulation CT
Why is Simulation and Positioning Necessary?
Radiotherapy is a treatment that uses high-energy radiation to destroy tumor cells. The key to its success lies in clearly identifying the tumor's precise location, surrounding structures, spatial relationships, and critical healthy tissues that require protection. It also involves positioning the patient comfortably in a way that meets radiotherapy requirements. The fundamental goal is to ensure radiotherapy "hits the target accurately" – neither under-dosing the tumor nor exposing healthy tissue to excessive radiation.
The Aquilion Lightning's whole-body imaging clearly captures the entire area requiring irradiation. Utilizing cutting-edge technology to optimize three-dimensional images, it intuitively displays the tumor extent and its relationship with adjacent organs, precisely defining tumor boundaries. It provides essential visual information for designing the irradiation plan and dose distribution when creating personalized radiotherapy regimens, effectively reducing the patient's radiation dose.
Safety – Low DoseEmploys the latest dose control systems and advanced ADIR 3D iterative reconstruction algorithms, which can reduce radiation dose by up to 75%.
Comfort – Large BoreA 78cm large bore is more suitable for positioning and immobilizing cancer patients. It fully accommodates larger individuals and special body surface areas, eliminates artifacts affecting accuracy, and ensures a comfortable experience.
Precision – High ResolutionBreakthrough innovations in the manufacturing process and Data Acquisition System (DAS) design enable more efficient and high-definition imaging (resolution up to 0.5mm), offering distinct advantages for detecting early lesions and improving the quality and accuracy of positioning CT images.
Differences Between Simulator CT and Standard Diagnostic CT
1. The simulator CT has a larger effective scanning radius and field size, can accommodate immobilization frames, adapts to any treatment position, and offers greater physical clearance.
2. While saving dynamic planar radiographs, the simulator CT allows more direct visualization of the target area.
3. The simulator CT enables visual assessment of the radiation field path through CT scanning and allows for real-time observation.
4. The positioning lasers of the simulator CT must accurately determine the isocenter position with the same precision as the laser system in the treatment room and must demonstrate excellent reproducibility with it. Its accuracy, stability, and reproducibility are superior to those of standard diagnostic CT scanners.
