Computed Tomography Protocol Optimisation for Pediatric Head Trauma: Radiation Dose and Image Quality Assessment

Purpose: Children are sometimes examined with Computed Tomography protocols designed for adults, leading to radiation doses higher than necessary. Lack of optimisation could lead image quality what is needed diagnostic purposes associated high patients. Optimising the paediatric head trauma CT imaging will reduce dose. Objective: The study aimed optimise dose and assess a set by evaluating noise, contrast noise ratio, modulation transfer function power spectrum. Methods: Somaton Sensation 64 was used scan an anthropomorphic phantom protocols. ImageJ software analyse from scanner. IMPACTSCAN dosimeter evaluate various organs in head. MATLAB Modulation Transfer Function Noise Power. Results: estimated Dose Index volume (CTDIvol) increased increasing tube current voltage. pitch 0.9 gave lower 0.5 pitch. eye lens received highest (39.2 mGy) whiles thyroid least (13.7 mGy). There increase (62.46) when H60 kernel (8.829) noticed H30 used. Conclusion: results obtained show that (smooth kernel) values ratio (CNR) (sharp kernel). produced (MTF) spectrum (NPS).
