PENGARUH PENERAPAN TEKNIK DESPECKLE FILTER LOCAL STATISTIC MEAN VARIANCE (DSFLSMV) TERHADAP KUALITAS CITRA DAN INFORMASI ANATOMI PADA CITRA ULTRASONOGRAFI PANKREAS DI INSTALASI RADIOLOGI RSUD CURUP
- Bagikan:
Background: Pancreatic ultrasound has a weakness, that is the presence of granular speckle noise and disturbing image quality. The local statistical mean variance (DsFlsmv) filter despeckle technique can reduce speckle noise and improve the quality of pancreatic ultrasound images.
Objective: To determine the effect of applying DsFlsmv despeckle filter technique on image quality and anatomical information on pancreatic ultrasound images.
Method: This type of quasi-experimental study used a pretest posttest without control group design. The study sample was 32 volunteers. Quantitative analysis of image quality used Paired T-test. Qualitative analysis on image information used Friedman test.
Results: Qualitative study of image quality shows differences in pancreatic ultrasound image information between pre-denoising, post-denoising size window 3x3 and post-denoising size window 5x5 images with a p-value < 0.001. The highest mean rank was obtained in the post-denoising size 3x3 images of 2.82. Quantitative study has different image quality (MSE and PSNR values) on pancreatic ultrasound post-denoising size 3x3 and post-denoising size window 5x5 images with p-value < 0.001. The lowest mean MSE value obtained in post-denoising size window 3x3 images is 5.063197 and the highest mean PSNR value in the post-denoising image size 3x3 images is 41.099753 dB.
Conclusion: The use of DsFlsmv technique with size window 3x3 can improve image quality and result the most optimal anatomical information on pancreatic ultrasound images.
