Abstract
Salah satu aspek penting dalam dunia medis adalah bagaimana melakukan diagnosis dan pengawasan pada keadaan fungsional organ tubuh, karena proses tersebut merupakan tahap awal untuk mengetahui ada tidaknya penyakit. Pada penelitian ini telah berhasil dibuat sebuah alat terpadu electrical impedance cardiography dan tomography (EICT) yang dapat berfungsi sebagai elektrokardiografi dan tomografi. Alat ini bekerja menggunakan prinsip kerja pengukuran impedansi listrik pada tubuh manuasia (bioimpedance). Tomografi merupakan metode pencitraan medis non invasif yang dapat digunakan untuk melakukan diagnosis dan pengawasan fungsional organ tubuh. Alat ini memiliki beberapa keunggulan antara lain non invasif, non radiasi pengion, mudah diaplikasikan, murah, dan portabel. Metode kerja alat kardiografi dalam yaitu dengan menginjeksikan arus listrik dan mengukur nilai tegangan listrik pada bagian leher dan sekitar diafragma subyek. Proses pengujian alat dilakukan pada subyek dengan kondisi kesehatan baik, dengan posisi duduk dan tegak. Sementara itu, metode kerja untuk alat tomografi yaitu dengan dengan menginjeksikan arus listrik dan mengukur nilai tegangan pada phantom uji. Proses penginjeksian arus listrik dan pengukuran tegangan listrik pada phantom dilakukan dengan elektroda sebanyak 16 unit dengan konfigurasi tetangga (neighboring method). Data nilai tegangan yang diperoleh akan diolah dengan bantuan software python untuk menghasilkan citra dari phantom uji. Hasil yang dicapai adalah alat yg dibuat mampu digunakan untuk mengilustrasikan grafik detak jantung sebagai akibat adanya aktifitas kardiovaskular, dan fungsi alat tomografi berbasis impedansi listrik dapat digunakan untuk memberikan citra pengamatan dari phantom uji.

A critical aspect in the medical field is how to diagnose and monitor the functional state of the organs inside the body. These processes are the initial stage to find out whether there is a disease or not. In this study, an Integrated Electrical Impedance Cardiography and Tomography (EICT) System that have a function as an electrocardiography and tomography device have been successfully fabricated. Tomography is a non-invasive medical imaging method that can be used to check and monitor the functional state of the organs. The device that have been fabricated in this research has several advantages, including non-invasive, non-ionizing radiation, easy to apply, inexpensive, and portable. The working principle in cardiography is by injecting electric current and then measuring the value of the electrical voltage in the neck and around the diaphragm of the subject. The testing process is carried out on patients in good health and in the positions of sitting and upright. Meanwhile, the working principle of the tomography is by injecting an electric current and measuring the voltage value on the phantom test. The process of injecting electric current and measuring the voltage on the phantom is done with 16 units of electrodes with a neighboring electrode configuration. The voltage data value obtained will be processed with the help of python software to produce images from the phantom test. The results achieved are tools that are capable of being used to illustrate heart rate charts as a result of cardiovascular activity, and the function of an electrical impedance-based tomography tool can be used to provide observational images from phantom test.
