Book Description
In this study, five different deep convolutional neural network-based models (AlexNet, VGGNet16, VGGNet19, GoogleNet, and ResNet50) have been selected for the investigation to detect the coronavirus infected patient using chest CT radiographs digital images. The classical data augmentations along with CGAN improve the performance of classification in all selected deep transfer models. The Outcomes show that ResNet50 is the most appropriate classifier to detect the COVID-19 from chest CT dataset using the classical data augmentation and CGAN with testing accuracy of 82.91%.

Book Description
Le but de cette étude était de développer un réseau neuronal convolutif (CNN) capable d'évaluer automatiquement le surcroît d'exposition sur l'axe Z liée à une longueur d'exploration inappropriée en scanner pulmonaire. 250 scanners thoraciques ont servi de données d'entrainement et 100 scanners de base de validation des résultats. Un marquage de la première et de la dernière coupe pulmonaire a été effectué sur chaque scanner par le CNN et 2 radiologues indépendants afin de définir trois zones (cervicale, pulmonaire et abdominale) pour ainsi évaluer la surexposition cervicale et abdominale. La précision du CNN a été calculée après la phase d'entrainement et la concordance CNN-radiologues a été obtenue par utilisation de statistiques kappa après la phase de validation. Une fois le logiciel validé, le CNN a été utilisé pour mesurer la longueur des trois aires anatomiques et la surexposition Z totale sur une cohorte rétrospective de 1000 patients. Une précision du CNN de 0.99 a été retrouvée pour l'ensemble des données d'entrainement et une bonne concordance CNN-radiologues a été obtenue (kappa=0.98) lors de la phase de validation. La surexposition globale atteignait 22.8% en utilisant le CNN et 22.2% avec les radiologues. La surexposition calculée par le CNN sur la cohorte de 1000 patients était de 22.6%. Notre étude montre une surestimation significative de la longueur d'exploration en scanner pulmonaire et de ce fait une surexposition aux rayons ionisants. Cette surexposition peut facilement être évaluée de manière fiable et rapide à l'aide de notre CNN.

Book Description
This book provides an overview of current and potential applications of artificial intelligence (AI) for cardiothoracic imaging. Most AI systems used in medical imaging are data-driven and based on supervised machine learning. Clinicians and AI specialists can contribute to the development of an AI system in different ways, focusing on their respective strengths. Unfortunately, communication between these two sides is far from fluent and, from time to time, they speak completely different languages. Mutual understanding and collaboration are imperative because the medical system is based on physicians’ ability to take well-informed decisions and convey their reasoning to colleagues and patients. This book offers unique insights and informative chapters on the use of AI for cardiothoracic imaging from both the technical and clinical perspective. It is also a single comprehensive source that provides a complete overview of the entire process of the development and use of AI in clinical practice for cardiothoracic imaging. The book contains chapters focused on cardiac and thoracic applications as well more general topics on the potentials and pitfalls of AI in medical imaging. Separate chapters will discuss the valorization, regulations surrounding AI, cost-effectiveness, and future perspective for different countries and continents. This book is an ideal guide for clinicians (radiologists, cardiologists etc.) interested in working with AI, whether in a research setting developing new AI applications or in a clinical setting using AI algorithms in clinical practice. The book also provides clinical insights and overviews for AI specialists who want to develop clinically relevant AI applications.

Book Description
This book constitutes the refereed joint proceedings of the Third International Workshop on Reconstruction and Analysis of Moving Body Organs, RAMBO 2018, the Fourth International Workshop on Breast Image Analysis, BIA 2018, and the First International Workshop on Thoracic Image Analysis, TIA 2018, held in conjunction with the 21st International Conference on Medical Imaging and Computer-Assisted Intervention, MICCAI 2018, in Granada, Spain, in September 2018. The 5 full papers (out of 10 submissions) presented at RAMBO, the 9 full papers (out of 18 submissions) presented at BIA, and the 20 full papers (out of 21 submissions) presented at TIA were carefully reviewed and selected. The RAMBO papers cover aspects of medical imaging where motion plays a role in the image formation or analysis. The BIA papers deal with topics such as computer-aided detection and diagnosis of breast cancer, quantitative analysis of breast imaging modalities, and large scale breast image screening and analysis. The TIA papers cover aspects of image analysis research for lung and cardiac diseases including segmentation, registration, quantification, modeling of the image acquisition process, visualization, validation, statistical modeling, biophysical lung modeling (computational anatomy), deep learning and novel applications.
