Ultrasound application allows for noninvasive visualization of tissue structures. Real-time ultrasound images are integrated images resulting from reflection of organ surfaces and scattering within heterogeneous tissues. Ultrasound scanning is an interactive procedure involving the operator, patient, and ultrasound instruments. Although the physics behind ultrasound generation, propagation, detection, and transformation into practical information is rather complex, its clinical application is much simpler. Because ultrasound imaging has improved tremendously over the last decade, it can provide anesthesiologists opportunity to directly visualize target nerve and relevant anatomical structures.
Bedside ultrasound has become an important modality for obtaining critical information in the acute care of patients. It is important to understand the physics of ultrasound in order to perform and interpret images at the bedside. The physics of both continuous wave and pulsed wave sound underlies diagnostic ultrasound. The instrumentation, including transducers and image processing, is important in the acquisition of appropriate sonographic images. Understanding how these concepts interplay with each other enables practitioners to obtain the best possible images.

This comprehensive resource provides clear explanations and numerous, simple line drawings that fully explain the "whys" of physics as applied to ultrasound. Material is clarified through the use of well-designed analogies, examples of digitally processed images, and learning features such as key terms, clinical examples, end-of-chapter review questions, mock registery exams, a glossary, and a math review appendix.

- Посмотрите уран. Его сверхкритическую массу. - М-м… сто десять фунтов, - сказала Соши.
В тридцати футах от них, скрытый за стеклом односторонней видимости Грег Хейл стоял у терминала Сьюзан. Черный экран.
Б нем не чувствовалось грубой силы Грега Хейла, скорее - жестокость отчаяния, внутренняя бездушная решительность. Сьюзан повернулась. Человек, попытавшийся ее удержать, выглядел растерянным и напуганным, такого лица у него она не видела. - Сьюзан, - умоляюще произнес Стратмор, не выпуская ее из рук.
