Abstract
X-ray images are acquired by transmitting X-rays through an object and recording the transmitted rays on film or with electronic detectors. X-rays are attenuated as they travel through an object, similar to the attenuation of visible light as it travels through a semiopaque material. The magnitude of attenuation depends on both the material and the distance the X-rays have to traverse in the material. The recorded intensity of the acquired image, therefore, provides information about the internal structure of the radiographed object. In medical imaging, X-rays have a wide range of applications and provide complementary information to other imaging modalities like magnetic resonance imaging (MRI), positron emission tomography (PET), single-photon emission computed tomography (SPECT), and ultrasound.
