Abstract

Backgroud: Imaging plate (IP) is a storage media on computed radiography (CR). IP that has been exposed and does not process immediately will decrease the latent image exponentially over time and degrade the image quality. Normally, 25% of signal will be lost if IP was scanned at 10 minutes till 8 hours after exposure. So It will decrease the image quality. Image quality is determined by several factors. One of them is the signal-to-noise ratio (SNR). This study aims to determine the effect of reading time delay of IP to SNR on CR image.Methods: This research was a quantitative study with an experimental approach. Population of this study was CR digital image with various time delay of IP reading. Samples were 51 digital images of water phantom read by IP reading with time interval was 0 hours, 0.5 hours, 1 hour; 1.5 hour, 2 hours, 2.5 hours, 3 hours, 3.5 hours, 4 hours, 4.5 hours, 5 hours, 5.5 hours, 6 hours, 6.5 hours, 7 hours, 7.5 hours and 8 hours after exposure. Image pixel value and noise was weasured by ImageJ software to determine the value of SNR, then analyzed statistically with the regression test.Results: There was effect of reading time delay to SNR on CR image. Time delay affected 30,5% decreasing of SNR. Generally, time delay of IP reading decrease the SNR. The average decrease was 1.55% of SNR.Conclusion: The decrease of the SNR value was not big enough, only 1.55%. However, it will better when IP read as soon as possible after exposure to reduce the decrease of image quality.

Abstract

Evaluation of CT-scan image results of hemorrhagic strokes was carried out using the volume evaluation software method manually; this method has several weaknesses in that the measurement takes a relatively long time. This researcher applies a digital image processing program with the help of Matlab software by utilizing the segmentation process of the Otsu thresholding method to measure hemorrhagic strokes. To determine differences in the results of hemorrhagic stroke measurements using the software volume evaluation method and the Otsu thresholding method. Quasi-experimental research with a post-test only control group design on CT-scan images. Create an otsu thresholding design using the Matlab R2021a program. Digital images were used as data for 32 CT-Scan images of the head. Processing and analysis of the results in this research used quantitative methods using the Mann-Whitney non-parametric statistical test. Measurement of hemorrhagic stroke using the software volume evaluation method with the Otsu thresholding method shows that there is a difference with a value of 0.04 with a p value < 0.05 and the software volume evaluation method has an average percentage difference of 59% from the Otsu thresholding method. Measurements using volume evaluation software take longer than the automatic Otsu thresholding method, but the results are not better than the volume evaluation software method. The software volume evaluation method is better in measuring hemorrhagic stroke volume compared to the Otsu thresholding method.
