ANALISIS PENGARUH GRID TERHADAP PENYIMPANGAN BENTUK DAN UKURAN OBJEK (DISTORSI)

Abstract

It had been done research about analyze of the grid impact into a distortion of the for, and measure of the object in the Laboratorium Faculty of Radio diagnostic and Radiotherapy PoltekKes Semarang. To get the result of analize of the gridimpact into a distortion of the form and measure of the object, we had measuring the comparation between the dimension of the concrete object and the dimension of radiography, and also the object with and without grid. Two object used in this research. First we have an object with 20 cm long, height and wide. And the second with 20 cm long, 20 cm wide and 10 cm height. The result we’ve got, there are structural change between radiograph within grid. But the grid-less radiograph are not changed. In the grid-less radiograph, there are shape distortion into un-symmetrical cubical which it is from symmetric cube. And also, there are change in the size of the texture into a bigger one.
