  • The components of effectiveness are organized around eight clinical areas. Naturally, some measures will cross components; for example, receipt of discharge instructions for heart failure is related to effectiveness of heart disease care as well as care coordination. For the purposes of this document, measures with clinical context are presented with the effectiveness measures. Other measure sets describe health care delivery and systems issues and are discussed together.

  • The purpose of this book is to provide a tutorial overview on the subject of computerized tomographic imaging. We expect the book to be useful for practicing engineers and scientists for gaining an understanding of what can and cannot be done with tomographic imaging. Toward this end, we have tried to strike a balance among purely algorithmic issues, topics dealing with how to generate data for reconstruction in different domains, and artifacts inherent to different data collection strategies....

  • The signal processing task is a very critical issue in the majority of new technological inventions and challenges in a variety of applications in both science and engineering fields. Classical signal processing techniques have largely worked with mathematical models that are linear, local, stationary, and Gaussian. They have always favored closed-form tractability over real-world accuracy.

  • Thyroid and parathyroid diseases are among the most frequent conditions we have to deal with in a clinical setting. Both nodular and autoimmune diseases affecting these glands have increased remarkably over the past decades. The widespread use of crosssectional imaging and the introduction of neck ultrasonography have led to a thyroid nodule epidemics and the diagnostic of neck lesions in half of the population. Consequently, many patients with microscopic papillary thyroid cancers of uncertain clinical significance are submitted to surgeries that may, perhaps, be unnecessary....

  • Regulation of female reproductive system consists of very complex interactions between the hypothalamus, neurohypophysis and ovaries. Beginning from the embryologic stage, female reproductive system is regulated by the brain. Ovarian hormone production is supressed by the hypothalamo-hypophyseal control mechanism till the end of the childhood period when the puberty begins. During puberty, menstrual cyclicity and timely ovulation, which are the result of the precise integration within different components of the reproductive system, are achieved.

  • The recent wide diffusion of (i) easy-to-use software tools for the implementation of Graphical User Interfaces (GUIs); and (ii) communication-oriented instrumentation, often provided with Ethernet interface, in addition to the more traditional GPIB and RS-232 ones, can be particularly exploited in the field of measurement teaching. It is well known, in fact, that for a better understanding of the teaching issues in such a field, the students have to practice with real instrumentation. The computer-based simulations are often inadequate to assure a good experience in that direction.

  • It is relatively easy to distinguish PZ from TZ on transverse views so that simultaneous images of both transverse and sagittal images make far lateral biopsy easy. For the sagittal images only, after identifying the center of prostate such as the line of urethra, then, slowly rotate ultrasound probe to the lateral part, so that far lateral PZ would be identified just after disappearing from TZ. For patients with middle to large prostate, far lateral PZ on sagittal images may sometimes represent only the mid-base of the prostate.
