Book excerpt: "In optical imaging, the depth and resolution are limited due to scattering. Unlike light, scattering of an ultrasound waves in tissue is negligible. Hybrid imaging methods such as ultrasound modulated optical tomography (UOT) use the advantages of both modalities. UOT tags light by inducing phase change caused by modulating the local index of refraction of the medium. The challenge in UOT is detecting the weak signal. The displacement induced by the acoustic radiation force (ARF) is another ultrasound effect that can be utilized to tag the light. It induces greater phase change, resulting in a stronger signal. Moreover, the absorbed acoustic energy generates heat, resulting in a change in the index of refraction and a strong phase change. Since the speckle pattern is governed by the phase of the interfering scattered waves speckle pattern analysis can obtain information about local displacement and temperature changes in the tissue. We have presented a model to simulate the insonation processes. Simulation results based on fixed-particle Monte Carlo and experimental results show that the signal acquired by utilizing ARF is stronger compared to UOT. The introduced mean irradiance change (MIC) signal reveals both thermal and mechanical effects of the focused ultrasound wave in different timescales. Simulation results suggest that variation in the MIC signal can be used to generate a displacement image of the medium. In addition to the displacement correlated image, the MIC signal can provide images based on the morphology of the tissue. The MIC signal can provide for tumor detection in a healthy tissue"--Author's abstract.

Download or read book Molecular Imaging in Oncology written by Otmar Schober and published by Springer Science & Business Media. This book was released on 2012-11-28 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of molecular imaging on diagnostics, therapy, and follow-up in oncology is increasing steadily. Many innovative molecular imaging probes have already entered clinical practice, and there is no doubt that the future emphasis will be on multimodality imaging in which morphological, functional, and molecular imaging techniques are combined in a single clinical investigation. This handbook addresses all aspects of molecular imaging in oncology, from basic research to clinical applications. The first section is devoted to technology and probe design, and examines a variety of PET and SPECT tracers as well as multimodality probes. Preclinical studies are then discussed in detail, with particular attention to multimodality imaging. In the third section, diverse clinical applications are presented, and the book closes by looking at future challenges. This handbook will be of value to all who are interested in the revolution in diagnostic oncology that is being brought about by molecular imaging.
Download or read book Applying High Frequency Ultrasound to Examine Structures and Physical Properties of Cells and Tissues written by Frank Winterroth and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Medical ultrasound is a diagnostic imaging technique used for visualizing subcutaneous body structures. The frequencies used in conventional diagnostic ultrasound are typically 2-10 MHz. For scanning acoustic microscopy (SAM), the frequencies applied to image cells and tissues are >50 MHz. Increasing the frequency increases spatial resolution, but reduces the depth that can be imaged. The advantages of using SAM over conventional light and electron microscopes include imaging specimens without requiring any preparations which may kill or alter them; this provides a more accurate representation of them. SAM's main components are similar to those found on typical light microscopes, but the lens is often replaced by a confocal transducer. The ultrasound signal encountering the specimen generally has three results: scatter, transmission, or reflection; these signals are then merged to form the image as either a B-Scan or C-Scan. The acoustic parameters determining the image quality are absorption and scattering. SAM can objectively quantify the surface characteristics of the specimen being scanned and can also study the elastic properties of cells and tissues to discern differences between healthy and affected conditions. SAM has the potential as a major instrument of detection and analyses in biomedical research and clinical studies.
