Document Summary
Is otropic voxel = element has equal length (dx = dy = dz ) In an image: voxel = volume element, pixel, image. Mathematical repres entation of an object (internal property of body) P hilos ophical information: ways to interrogate the body following the a l ar p p rinciple (as low as reas onably pos s ible): B uilding block - photon / quanta of energy. S inus oidal repetitive trans vers e wave. S peed of light (3 x108 m/s : medical imaging = interaction of energ y/ light and matter/body of patient and us e that to generate image/ repres entation to s eek problem of the patient. C onvention - patient is always looking at doctor, s o left s ide of image is as if patient is looking at you. S uperior to inferior (up to down: image q uality.
