DOWNLOAD EBOOKThe use of ultrasonic imaging techniques for diagnostic purposes in veteri nary medicine and animal science has lagged far behind their use in human medicine. In the area of domestic animal reproduction, diagnostic ultrasono graphy has a relatively short history. Reports on B-mode scanning first appeared as late as 1969, when Stouffer and co-workers used it for counting foetal numbers in late gestation sheep. After Lindahl had re-evaluated the potential of two-dimensional ultrasonography for pregnancy diagnosis in sheep in 1976, results of the first large scale field-trials by Fowler and Wilkins on predicting foetal numbers during the first half of gestation in sheep were published as recently as 1980. In this year also the first paper, by Palmer and co-workers, on ultrasonic scanning of the uterus and ovaries in the mare appeared. The improvement of diagnostics which was achieved by the application of this technique is illustrated by its present routine use in clinical equine practice and sheep breeding. Besides offe ring an accurate early pregnancy diagnosis in species such as the horse, cow, sheep, goat, pig and dog, ultrasonography enables the visualization of ovarian and uterine structures for the identification of both physiological and pathological conditions. In this way it replaces or supplements the more common diagnostic techniques used by the general practitioner so far. Ultrasonography has also opened several new lines of research for clini cians and research workers.

DOWNLOAD EBOOKDespite efforts to control udder health in cattle, are the causes of mastitis are on the rise. Although at first glance the birth process seems normal in domestic pigs, what could be the problem? What are the clinical aspects of the oestrus cycle and pregnancy endocrinology in mares? What is Lidia cattle breeding and clinic? Does calf gender affect milk yield? Do insecticides reduce fertility? Could boar pheromones be an option to stimulate sow reproduction? Animal Reproduction in Veterinary Medicine is a book with the answers to such questions. It includes ‘Induction and Synchronization of Estrus’, which describes the protocol principles and tools. The practical approach this book takes will help students, farmers, veterinarians and academics to build an understanding of the concepts and procedures required to answer real questions by comprehending the basic function of real clinic data. Humans often endure results from the misunderstanding that to be doing well, they should make each thing themselves.

DOWNLOAD EBOOKThis new version of Frances Barr’s classic introductory text, Diagnostic Ultrasound in the Dog and Cat, has now been revised and expanded to cover the considerable technological and knowledge based advances since the first book was published in 1990. With contributions from leading subject experts, this new book covers both the theoretical principles behind the use of ultrasound in small animal practice and the practical approach to image interpretation. In-keeping with the user-friendly style of Frances Barr’s book, the book is extensively illustrated with photographs and accompanying line drawings. Organised around body systems, each chapter covers imaging procedures, normal appearances, abnormal appearances/diseases and specific conditions. Exotic animals, such as rabbits and reptiles are also included, as are new Doppler techniques. This practical guide is essential reading for all those involved in small animal imaging.

DOWNLOAD EBOOKThis open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.
Considerations Underlying the Use of Ultrasound to Detect Gallstones and Foreign Bodies in Tissue

DOWNLOAD EBOOKThe densities of a number of gallstones have been determined and found to vary between 0.82 and 1.10 gm/cc. The velocity of ultrasound through gallstone slabs, beef tissue, and living human muscles has been measured. The velocity through the gallstones varied between 1400 and 2200 m/sec. The velocity through the calf, thigh, and arm muscles of five subjects was found to vary between 1490 and 1610 m/sec with a mean value of 1540 m/sec. The mean velocity through beef tissue at 20-21C was 1540 m/sec. From these data the characteristic acoustic impedance of gallstones and of tissue was determined. Values between 130,000 and 230,000 gm/sq cm/sec were found for the gallstones measured. The acoustic impedance of tissue consisting mostly of muscle is 160,000 to 170,000 gm/sq cm/sec. The energy reflection coefficient for a gallstone in tissue was calculated, and the theoretical feasibility of detecting gallstones by the use of ultrasonic echo-ranging was established. Large signals were obtained from gallstones implanted in the back muscles and in the gallbladders of dogs. A frequency range of 1.0 and 2.5 megacycles has been found to be optimum for an ultrasonic instrument for diagnostic purposes. Penetration of soft tissues for 15 cm or more is afforded, without reaching damaging intensity levels. The wave length in tissue 0.6 to 1.5 mm. provides adequate resolution for the detection of gallstones and most foreign bodies. The possibility of detecting foreign bodies and tumors by use of the echo-ranging principle is discussed. (Author).
