The advent of X-ray Computed Tomography (CT) as a tool for the soil sciences almost 40 years ago has revolutionised the field. Soil is the fragile, thin layer of material that exists above earth's geological substrates upon which so much of life on earth depends. However a major limitation to our understanding of how soils behave and function is due to its complex, opaque structure that hinders our ability to assess its porous architecture without disturbance. X-ray imagery has facilitated the ability to truly observe soil as it exists in three dimensions and across contrasting spatial and temporal scales in the field in an undisturbed fashion. This book gives a comprehensive overview of the "e;state of the art"e; in a variety of application areas where this type of imaging is used, including soil water physics and hydrology, agronomic management of soils, and soil-plant-microbe interactions. It provides the necessary details for entry level readers in the crucial areas of sample preparation, scanner optimisation and image processing and analysis. Drawing on experts across the globe, from both academia and industry, the book covers the necessary "e;dos and don'ts"e;, but also offers insights into the future of both technology and science. The wider application of the book is provided by dedicated chapters on how the data from such imagery can be incorporated into models and how the technology can be interfaced with other relevant technical applications. The book ends with a future outlook from the four editors, each of whom has over 20 years of experience in the application of X-ray CT to soil science.

This book describes the roles magnetic resonance imaging (MRI) can play in deep brain stimulation (DBS). DBS therapeutically modulates aberrant neural circuits implicated in a broad range of neurological disorders. Following surgical insertion, an electrode placed into the desired brain target generates constant electricity, analogous to a cardiac pacemaker. Most commonly employed in movement disorders such as Parkinson's disease, dystonia, and tremor, DBS is also being investigated for use in psychiatric and cognitive disorders, including depression and Alzheimer's disease. It is estimated that more than 230,000 patients have undergone DBS surgery worldwide. Imaging techniques, specifically MRI, have played key roles in the preoperative and postoperative aspects of DBS.  This book focuses on the established as well as the innovative roles of MRI in DBS. MRI and DBS are first introduced from an historical perspective and a review of the clinical aspects of DBS is performed. Then, the preoperative and postoperative applications of MRI in DBS are covered. The crucial aspect of MRI safety in these patients is also discussed. Finally, possible upcoming MRI applications for patients with DBS are discussed in a future directions chapter. Chapters are written by experts from the University of Toronto, a world leader in the field of DBS, alongside international co-authors to ensure a thorough review of the topics. This is an ideal guide for both clinicians (neurosurgeons, neurologists, psychiatrists, and neuroradiologists) and researchers as well as trainees interested in neuroimaging for DBS.
