Pengaruh Tegangan Tabung terhadap Kualitas Citra pada Pemeriksaan Computed Tomography Kepala menggunakan Iterative Reconstruction

Iterative reconstruction can optimize radiation dose and improve image quality on CT scan. This research method is quantitative analytic with the analysis of results head examination parameters associated to changes in variations 80 kV, 100 120 kV use iterative reconstruction. Image measurements are Hounsfield Unit (HU) value, standard deviation, Signal Noise Ratio (SNR) using Radiant Viewers. Effective measurement Dose Length Product (DLP). Then perform Kruskal Wallis test find out whether there an effect tube voltage Reconstruction SNR value IBM SPSS version 24. The HU increase due but does not change significantly when iDose changes, for deviation has decreased experience a significant at time iDose, while increases iDose. percentage ratio effective by 62%, was decrease 25%, experienced 25%. p-value <0.001, therefore it be concluded that difference each parameters.
