Core Viewpoint - The procurement project for X-ray and spectral testing systems at Hohai University has announced the winning bid, with Sanying Precision winning the bid for the 3D X-ray imaging analysis system segment at a price of 6.295 million yuan [1][3]. Summary by Sections Project Overview - The total budget for the project is 8.72 million yuan, aiming to procure seven sets of instruments, including the 3D X-ray imaging analysis system (budgeted at 6.8 million yuan), UV-visible spectrophotometer, UV-visible diffuse reflectance spectrometer, inductively coupled plasma spectrometer, full-spectrum direct-reading spectrometer, micro-arc oxidation system, and high-power anodizing system [2]. Winning Bid Details - Sanying Precision successfully won the bid for the 3D X-ray imaging analysis system segment with a bid amount of 6.295 million yuan, specifically for the model nanoVoxel-5000 [3][6]. Technical Specifications - The system features a maximum spatial resolution of 500nm and a testing resolution of ≤1μm when the working distance (distance from X-ray source to sample rotation axis) is 50mm, suitable for high-resolution and in-situ loading imaging [7]. - It supports multiple scanning imaging modes, including real-time DR projection, circular trajectory cone beam CT, ultra-wide local high-resolution cone beam CT, spiral cone beam CT, offset cone beam CT, limited angle cone beam CT, and super-resolution CT scanning [7]. - The system is equipped with an in-situ multi-coupling loading device, sub-pixel super-resolution imaging capability, and detector jitter anti-aliasing features, along with image acquisition software, image reconstruction software, and defect analysis software [7]. - The high-resolution objective lens coupled detector consists of a high-resolution camera, optical lens, scintillator, turret, etc., and includes optical lenses of 4X, 10X, and 20X, enabling high-resolution imaging under in-situ loading conditions [7]. - The X-ray shielding box is designed with a safety lock, X-ray activation display, and radiation dose equivalent of <0.8μSv/h at any position 20mm away from the box, complying with national standards [7].
