Book Synopsis Biophysical Methods for Diagnosing Human Tissue Anomalies by : Nathan Blaunstein
Download or read book Biophysical Methods for Diagnosing Human Tissue Anomalies written by Nathan Blaunstein and published by Cambridge Scholars Publishing. This book was released on 2024-02-27 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medical diagnosis of tissue anomalies, particularly cancer, is often limited by the constraints of current imaging technologies. This book introduces two approaches to address this issue: the imaging and the non-imaging methods. In the imaging category, the book unveils a pioneering technique based on radio tomosynthesis. Initially proven effective in detecting breast anomalies, this imaging method is now under evaluation for its potential in identifying brain anomalies. For non-imaging diagnostics, it delves into Fourier-transform infrared spectroscopy (FTIR), a technique known for its speed and reliability. The book demonstrates its successful application in diagnosing a range of cancers, including oral, uterine, ovarian, gastrointestinal, colorectal, and skin cancers. Furthermore, it explores its utility in predicting embryo quality and assessing pressure injuries. To augment these methods, the book employs machine learning algorithms, evaluating their efficacy in creating discriminative models for tissue anomalies.

Book Synopsis Experimental Investigations of Optical Propagation in Atmospheric Turbulence by : Michael W. Fitzmaurice
Download or read book Experimental Investigations of Optical Propagation in Atmospheric Turbulence written by Michael W. Fitzmaurice and published by . This book was released on 1971 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pertinent theoretical background and the results of a group of experiments conducted over 0.4- and 1.17-km near-ground horizontal ranges are presented. (1) The log-amplitude variances for HeNe (0.633 μm) and CO2 (10.6 μm) laser beams were found to have a ratio of 26.8, which is in close agreement with the predictions of Rytov-based spherical-wave theory. (2) Published measurements of the saturation level of the log-amplitude variance are reviewed and several inconsistencies noted. (3) The spatial correlation function of irradiance field was measured and found to agree with theory. The degree of correlation between different frequency beams which had traversed the same optical path was also measured and compared to theory. The data exhibited an unacceptably large scatter and did not show the wavelength dependence. (4) The log-normal, Rayleigh, and Rice probability distributions are discussed in terms of their applicability to irradiance statistics. Relatively weak 10.6 μm irradiance fluctuations were found to be equally well described by the log-normal and Rice distributions; strong fluctuations obtained at 0.488 μm were clearly best described by the log-normal distribution.
