Evaluation of Diagnostic Systems: Methods from Signal Detection Theory addresses the many issues that arise in evaluating the performance of a diagnostic system, across the wide range of settings in which such systems are used. These settings include clinical medicine, industrial quality control, environmental monitoring and investigation, machine and metals inspection, military monitoring, information retrieval, and crime investigation. The book is divided into three parts encompassing 11 chapters that emphasize the interpretation of diagnostic visual images by human observers. The first part of the book describes quantitative methods for measuring the accuracy of a system and the statistical techniques for drawing inferences from performance tests. The subsequent part covers study design and includes a detailed description of the form and conduct of an image-interpretation test. The concluding part examines the case study of a medical imaging system that serves as an example of both simple and complex applications. In this part, three mammographic modalities are used: industrial film radiography, low-dose film radiography, and xeroradiography. The case study focuses on the overall reliability of accuracy indices made by its main components, that is, the variabilities across cases, across readers, and within individual readers. The supplementary texts provide study protocols, a computer program for processing test results, and an extensive list of references that will assist the reader in applying those evaluative methods to diagnostic systems in any setting. This book is of value to scientists and engineers, as well as to applied, quantitative, or experimental psychologists who are engaged in the study of the human processes of discrimination and decision making in either perceptual or cognitive tasks.

This book is a practical guide to the diagnosis of respiratory disorders, helping clinicians recognise signs and symptoms, decide on the most appropriate diagnostic tests, and to interpret the results. Divided into four sections, the book covers respiratory system assessment, evaluation of respiratory function, diagnostic imaging, and invasive diagnostic techniques. The imaging section includes radiograph, computed tomography, angiography, and ultrasonography. The invasive diagnostic procedures section covers bronchoscopy, lung biopsy, transbronchial needle aspiration and more. Video-assisted thoracic surgery as a diagnostic tool is also discussed. Authored by recognised expert Professor Claudio Sorino from University of Palermo, this useful manual is enhanced by clinical images and figures.

Statistical evaluation of diagnostic performance in general and Receiver Operating Characteristic (ROC) analysis in particular are important for assessing the performance of medical tests and statistical classifiers, as well as for evaluating predictive models or algorithms. This book presents innovative approaches in ROC analysis, which are relevant to a wide variety of applications, including medical imaging, cancer research, epidemiology, and bioinformatics. Statistical Evaluation of Diagnostic Performance: Topics in ROC Analysis covers areas including monotone-transformation techniques in parametric ROC analysis, ROC methods for combined and pooled biomarkers, Bayesian hierarchical transformation models, sequential designs and inferences in the ROC setting, predictive modeling, multireader ROC analysis, and free-response ROC (FROC) methodology. The book is suitable for graduate-level students and researchers in statistics, biostatistics, epidemiology, public health, biomedical engineering, radiology, medical imaging, biomedical informatics, and other closely related fields. Additionally, clinical researchers and practicing statisticians in academia, industry, and government could benefit from the presentation of such important and yet frequently overlooked topics.

This book is a collection of papers, exploring how designers, researchers and practitioners respond to the changing nature of contemporary perceptions of the relationship between humans and technology. Originating from a workshop at the 2012 Design Research Society Conference in Bangkok, the book presents diverse approaches from theoretical explorations to practical methods and educational solutions. The papers are presented in three sections with the first providing background information to the workshop and the perceptions of the relationship between humans and technology. Section two explores the theme of emotions and technology, investigating emotional responses to design solutions, methods for tracing facial and body expressions and the creation of the Kansei Design Education programmes. The final section is titled ‘Design and Technology’ and provides perspectives on how everyday and educational environments transform in response to the changing nature of the relationship between humans and technology. The book does not aim to provide a unified voice on how design practices change in response to new technologies, but it provides a platform for diverse cross-disciplinary debates on how designers and design educators respond to the changes in our contemporary understanding of the humans/technology relationship.

Advances in the standardization, precision and thoroughness of psychiatric diagnosis are being supplemented with attention to personalized or ideographic descriptive approaches. This promises not only to enhance the clinician's understanding of a case but to allow a fuller and more effective use of the evolving range of therapeutic possibilities. To reflect these developments, the Section on Classification, Diagnostic Assessment and Nomenclature of the World Psychiatric Association has prepared this volume which is organized around five prominent themes in contemporary psychiatric diagnosis: -major regional perspectives - ICD-10 - comprehensive diagnosis through the multiaxial model - treatment planning and organization of health services - the role and challenges of psychiatric diagnosis in primary health care.
