Offering a detailed account of standard magnifying endoscopy able to visualize subepithelial mucosal microvessels, the smallest unit in the human body, this book includes material on narrow-band imaging and the early diagnosis of gastric neoplasias.

Since magnifying endoscopy of the stomach, or zoom gastroscopy, was first performed at the beginning of the 21st century, there have been numerous findings in the field worldwide. The author of this volume has developed a standardized magnifying endoscopy technique that enables endoscopists to constantly visualize the microanatomy (subepithelial capillaries and the epithelial structure) within the stomach. With this technology, it has become easy to obtain magnified endoscopic findings. Techniques differ, however, depending upon the endoscopist. Endoscopists around the world do not have a...

People today worry about threats from radiation exposure. Such concerns have been backed up in the past when A-bombs were used in Hiroshima and Nagasaki during World War II, and from exposures which resulted from accidents in nuclear power plants in Chernobyl and Fukushima. In the past decade, knowledge of the effects of radiation at the molecular level, including DNA damage and repair, has advanced dramatically. This book describes the current state of knowledge in the fields of radiation effects, the medical uses of radiation, and radiation protection. It also considers past nuclear...

This book equips readers with the fundamentals of 3DCG that support the advanced technologies. The content of this book is divided into four categories: modeling, rendering, character animation, and physical simulation, and each is explained in a separate chapter. In simpler terms, these four technologies can be described as creating shapes, creating images, creating motion, and reproducing the behavior of the natural world. The "Modeling" chapter describes the theory behind describing the shape of an object using surface meshes and then editing and manipulating them. The chapter "Rendering"...
