Rekonstruksi Citra Tomografi Kapasitansi Elektrik Menggunakan Metode Proyeksi Balik Linear Iteratif

Abstract

The aim of this research is to observe the quality of images resulting from electrical capacitance tomography using iterative linear back projection. Tests have been conducted using a rod and straw(s) that put inside an 8 electrode capacitive sensor with various positions. Dispite the size of the reconstructed images are bigger that that of original object(s), the linear back projection method can correctly indetify the position of object(s). In order to over come the inaccuracy of image sizes, the method is used iteratively. Resulting tests suggest 50 iterations can improve the reconstructed images as expected.
