Abstract

This research focuses on determining the CT number, which is the attenuation coefficient value of x-rays after passing through an organ. The level of energy attenuation depends on the initial energy of the x-rays and the atomic number of the object, which play a role in describing differences in the characteristics of organs or body tissues. This research aims to ensure the suitability of the CT number to obtain accurate information about CT scan images. Research procedures include observation, data collection, and data processing. The CT number data from the experimental results was then compared with the simulation results using IndoQCT software. The CT Number conformity test is carried out on a water phantom by adjusting the tube voltage, input current, and slice thickness. The Region of Interest (ROI) is made in the form of a circle at five measurement points, namely the central direction, 3 o'clock, 6 o'clock, 9 o'clock, and 12 o'clock. The research results, both direct testing and simulation using IndoQCT software, show that the CT number does not exceed the accuracy tolerance limit and uniformity, respectively, -4 ˂ HU ˂ +4 and -2 ˂ HU ˂ +2. Based on the analysis results, it can be concluded that the CT number measurements in the Radiology Unit at the Yogyakarta PDHI Islamic Hospital meet the requirements of BAPETEN Perka Number 2 of 2018.

Abstract

Penelitian ini bertujuan untuk menganalisis integrasi teleradiologi dalam sistem pelayanan kesehatan serta mengidentifikasi manfaat, tantangan, dan implikasinya terhadap peningkatan kualitas layanan. Metode yang digunakan adalah penelitian kualitatif dengan pendekatan deskriptif melalui studi pustaka, dengan teknik pengumpulan data berupa penelusuran literatur, analisis dokumen, dan kajian teoritis terhadap berbagai artikel ilmiah, laporan penelitian, dan dokumen relevan. Analisis data dilakukan secara induktif melalui tahapan identifikasi tema, reduksi data, kategorisasi konsep, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa teleradiologi berperan penting dalam meningkatkan akses layanan diagnostik, mempercepat waktu diagnosis, serta meningkatkan efisiensi alur kerja radiologi, terutama di wilayah dengan keterbatasan tenaga medis. Namun, implementasinya masih menghadapi berbagai kendala, seperti keterbatasan infrastruktur, kurangnya integrasi data, isu keamanan informasi, serta kesiapan organisasi dan sumber daya manusia. Temuan ini menegaskan bahwa keberhasilan integrasi teleradiologi sangat bergantung pada kesiapan teknologi, regulasi, dan manajemen sistem yang terintegrasi. Secara keseluruhan, penelitian ini memberikan kontribusi dalam memperkuat pemahaman mengenai peran teleradiologi sebagai bagian dari transformasi digital pelayanan kesehatan serta memberikan dasar bagi pengembangan kebijakan dan praktik yang lebih efektif di masa depan.
