To address this, we propose a fast-scanning technique with limited projections and compare two reconstruction methods: Filtered Back Projection (FBP) and a combination of FBP with Simultaneous Iterative Reconstruction Technique (SIRT). The study was conducted on an industrial X-ray CT system at the Department of Physics, Universitas Gadjah Mada. A cylindrical water phantom (4” diameter) containing four solid inserts, aluminium, PTFE, graphite, and acrylic, was scanned using six different projection counts: 360, 180, 144, 108, 72, and 36. Each reconstruction result was evaluated against the reference image (360 projections) using mean square error (MSE), structural similarity index (SSIM), and signal-to-noise ratio (SNR). SIRT-FBP produced smoother images with less noise (SNR ≥20.33 dB, SSIM ≈ 0.9), while FBP generated sharper but noisier results (SNR ≤17.20 dB, SSIM ≈ 0.6). MSE values also indicated higher accuracy for SIRT-FBP. However, SIRT-FBP required longer computation time (100 s) compared to FBP (45 s). Both methods showed significant quality degradation at 72 and 36 projections, with blurry and low-contrast images. Acceptable image quality was achieved with a minimum of 108 projections.</div></div>","PeriodicalId":8096,"journal":{"name":"Applied Radiation and Isotopes","volume":"230 ","pages":"Article 112476"},"PeriodicalIF":1.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146184846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This barrier is acute for iridium metal targets used to produce platinum radioisotopes, where post-irradiation processing is costly and hazardous with conventional routes. We report a rapid alkali-fusion method that converts Ir metal directly into chloride media compatible with downstream separations. In the process, an Ir foil is fused with Na₂O₂ and KCl at temperatures above the KCl melting point; the molten salt enhances heat transfer and facilitates O²⁻/Na⁺ transport to the Ir surface, overcoming Ir's oxidation resistance. The fused cake is then cooled and leached in 10 M HCl, yielding Ir in solution without specialized microwave digestion or HF. Pt separation from bulk Ir was evaluated using extraction-chromatography resins.

This study employed a comprehensive multi-technique molecular analysis approach using Electron Paramagnetic Resonance (EPR), Positron Annihilation Lifetime Spectroscopy (PALS), and Small-Angle X-ray Scattering (SAXS) to investigate the performance gap between nanofiber-reinforced woven (NFW) and surface-coated (SC) nitrile gloves subjected to clinically-relevant radiation doses (10–25 kGy). The main finding revealed that NFW gloves achieve 2.5-fold longer service life than SC alternatives through superior molecular-level protection mechanisms. EPR spectroscopy showed SC gloves developed 61 % higher radical concentration than NFW gloves at 25 kGy (8.7 × 10¹⁷ vs 5.4 × 10¹⁷ spins/g), with NFW exhibiting superior radical stability (62 % retention at 168h versus 43 % for SC gloves). PALS demonstrated NFW's significantly lower Void Expansion Coefficient (0.07 vs 0.41 ų/kGy), correlating with reduced oxygen diffusion rates (1.4 × 10⁻⁹ vs 8.7 × 10⁻⁹ cm²/s). SAXS analysis established superior Structural Preservation Quotient for woven architecture (0.81 vs 0.33), reflecting enhanced nanoscale organizational stability. NFW gloves retained 68 % of tensile strength at 25 kGy compared to only 42 % for SC gloves, demonstrating practical performance advantages. Integration of these molecular parameters into a comprehensive Molecular Protection Factor (5.7 vs 2.3) enabled accurate prediction of mechanical performance retention with 92 % correlation across the radiation spectrum. Three-dimensional woven integration provided extended Effective Protection Period of 42 months versus 17 months for surface-concentrated alternatives. The protection mechanism hierarchy demonstrated stress distribution effectiveness as the primary factor (41 % contribution), followed by radical isolation (27 %), void restriction (19 %), and network balance (13 %).
