The interest in using the micro-bubbles for blood pressure measurements in the left ventricle of the heart and other organs has been raised in the last years. This task requires better understanding of the micro-bubbles properties driven by acoustic force and the conditions for creation of non-linear effects such as appearance of half-harmonic component in the signal radiated from the micro-bubbles. This work uses laboratory experiments in order to investigate the conditions for creation of half-harmonic component. The experiments are designed to better understand the micro-bubble properties and to explore the possible methods for future applications of micro-bubbles for blood pressure measurements. The response of the micro-bubbles to the driving ultrasound force is defined by their physical properties: micro-bubbles resonance frequency , the distribution of the micro-bubbles population radii and gas diffusion process.The micro-bubbles respond in a non-linear manner to the acoustic pressure above specific threshold.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659764462\"\u003e\u003ch3\u003eMicro-Bubble Based Pressure Measurements Using Ultrasound: Modeling and Signal Processing Research\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659764462","offer_id":39449973031005,"sku":"9783659764462","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ad78bdc8-2d5f-46d8-80ee-f2f177510a67.jpg?v=1773378966","url":"https:\/\/shop.autorenwelt.de\/products\/micro-bubble-pressure-measrement-using-ultrasound-micro-bubble-based-pressure-measurements-using-ultrasound-modeling-and-signal-processing-research-von-alex-rosen","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
