Manyetik Rezonans Görüntüleme Fizik Temelleri ve Sistem Bileşenleri

Abstract

Manyetik rezonans görüntüleme (MRG), fiziğin temel ilkelerinden yola çıkarak doku farklılıklarından kaynaklı görüntü elde edilmesi prensibine dayanan tıbbı görüntüleme tekniğidir. Hem görüntünün elde edilmesi sürecinde hem de manyetik rezonans cihazının yapısal bileşenlerinin üretimi ve çalışması sürecinde fiziğin temel ilkeleri önemli rol oynamaktadır. Bu derlemede, MRG’nin tarihinden kısaca bahsedilerek, görüntülemenin temelinde yatan fiziksel prensipler anlatılmıştır. Bu anlatılanlar ışığında MR cihazının temel yapısal elemanları tanıtılarak her bir sistem bileşenin nasıl çalıştığı ifade edilmiştir.

Magnetic Resonance Imaging Principles of Physics and System Components

Abstract

Magnetic resonance imaging (MRI) is a medical imaging technique based on the principle of obtaining images from tissue differences using the basic principles of physics.  The basic principles of physics play an important role both in the process of obtaining the image and in the process of production and operation of the components of magnetic resonance device. In this review, the history of MRI was briefly mentioned and the underlying physical principles of imaging were explained. Then, the basic structural elements of the MR device have introduced and how each system component works.
