Abstract

Ideal body weight is everyone's dream. Not only does having a body shape support your appearance, ideal body weight also indicates a healthy body condition. Maintaining body weight is one of the main keys to having a healthy and fit body. To find out whether our weight is ideal, we can see it from the Body Mass Index (BMI) measurement. BMI is measured by comparing height and weight. Basically, BMI is a benchmark that can be used as a way to find out ideal body weight. As time progresses, the use of existing technology is widely applied in the world of health. One of them is a BMI Calculator that uses a microcontroller such as Arduino UNO. BMI Calculator is a measurement tool commonly used to evaluate a person's Body Mass Index (BMI). This tool helps individuals and healthcare professionals to quickly determine whether a person is within a healthy weight range, underweight, or overweight.

Abstract

This study aims to design and build an Ultrasonography (USG) Phantom as an ultrasound calibration medium with more affordable materials but still meets quality and precision standards. The USG Phantom is designed using two basic materials, namely distilled water and engine oil, to then compare its performance in producing ultrasonic images. The research method used is an experiment with the stages of tool design, phantom manufacturing, and functional testing using Vertical and Horizontal Distance parameters. Testing was carried out with a convex USG transducer at Roemani Muhammadiyah Hospital Semarang. The test results show that the engine oil-based phantom provides a clearer and more stable image compared to water. The results of vertical distance measurements show the smallest absolute error value of 0.01cm (0.1mm) on objects 1–2 with a relative error value of 0.3%, and the largest of 0.09cm (0.9mm) on objects 7–8 with a relative error value of 4.5%. Meanwhile, for horizontal distance, the smallest absolute error value was recorded at 0.14 cm (1.4 mm) on objects 1–2 with a relative error value of 6.8%, and the largest was 0.19 cm (1.9 mm) on objects 2–3 and 4–5 with a relative error value of 9.5%. All vertical and horizontal error values ​​were still within the AAPM TG‑1 tolerance limits, which were ±2 mm or ±2% for vertical measurements and ±3 mm or ±3% for horizontal measurements. Thus, the engine oil phantom can be categorized as a suitable ultrasound calibration medium that is economical, effective, and meets international accuracy standards. This research is expected to be a practical solution for healthcare facilities to perform ultrasound calibration at a lower cost.
