Abstract

Medical implants are routinely tracked and monitored using different techniques, such as MRI, X-ray, and ultrasound. Due to the need for ionizing radiation, the two former methods pose a significant risk to tissue. Ultrasound imaging, however, is non-invasive and presents no known risk to human tissue. Aerogels are an emerging material with great potential in biomedical implants. While qualitative observation of ultrasound images by experts can already provide a lot of information about the implants and the surrounding structures, this paper describes the development and study of two simple B-Mode image analysis techniques based on attenuation measurements and echogenicity comparisons, which can further enhance the study of the biological tissues and implants, especially of different types of biocompatible aerogels.

摘要

医疗植入物通常使用不同的技术进行跟踪和监测，如磁共振成像（MRI）、X射线和超声。由于需要电离辐射，前两种方法对组织构成重大风险。然而，超声成像是非侵入性的，对人体组织不存在已知风险。气凝胶是一种在生物医学植入物中具有巨大潜力的新兴材料。虽然专家对超声图像的定性观察已经可以提供许多关于植入物和周围结构的信息，但本文描述了基于衰减测量和回声性比较的两种简单B模式图像分析技术的开发和研究，这可以进一步加强对生物组织和植入物，特别是不同类型生物相容性气凝胶的研究。
