The following two duties are expected of us: (1) to assist in interpretation of diagnostic images, and (2) to provide detailed explanations of radiological examinations. As professionals, we owe it to our clients to maintain our competence in perceiving the reality of each person’s condition during radiological examinations; we must neither nderestimate their radiation exposure risks nor overestimate the benefits they may receive from the examination. When assisting in interpretation of diagnostic images, we must understand the characteristics of images that can affect our assessment. Moreover, turning to the topic of reconstructed images, much information can be gathered from images utilizing the full capability of econstruction algorithms. Image quality is highly dependent upon the method of reconstruction (calculation of tomographic images). Reconstruction can be broadly classified into the following two types: filtered back projection and iterative reconstruction.
