Abstract

This study aims to compare the stability of materials and grayscale image quality of agar and oil-based ultrasonography (USG) phantoms. The method used includes making two types of phantoms with the same object, then imaging using a MINDRAY brand Ultrasography (USG) device type DP-10. Grayscale data was analyzed by calculating the average, standard deviation, and visual evaluation based on homogeneity, contrast, noise, and edge sharpness. The results showed that both phantoms had grayscale values ​​that were still within the tolerance range of ±10% of the average, indicating the stability of wave propagation at an acceptable depth. However, the oil phantom showed a higher average intensity value of 9.838 cm and a lower standard deviation of 0.152053, compared to agar 9.584 cm and a standard deviation of 0.202. The oil phantom image appeared more homogeneous, sharp, and had minimal noise compared to the agar phantom. Thus, the oil-based phantom is considered superior in producing stable and representative grayscale image quality, and is more durable than agar
