Ultrasound Tomography for Lung Imaging: An Experimental Phantom Study
نویسندگان
چکیده
The ability to create real-time images of pulmonary function is highly desirable in many clinical situations. For example, information on air delivery vital for patients the intensive care unit (ICU) who are going through mechanical ventilation due respiratory failure. functional obtained from imaging can be used provide early warnings developing pathologies real time, reducing complications and improving patient outcomes. Electrical impedance tomography (EIT) an system that has gone studies provides such information. EIT several drawbacks most important one its limited spatial resolution very low depth, which cannot avoided by adding more electrodes. Therefore, it possible introduce ultrasound (UST) as technique with potential nonionizing monitoring lung imaging. In contrast, UST show significant enhancement when transducers used. central region thorax detected enhanced area. this work, we developed a realistic geometry phantom focusing performances 3-D applications. Results validated using experimental thoracic phantoms representing use achieved detecting reconstructing changes sound velocity distribution resulting functions conditions.

To increase the temperature contrast in thermal images, the characteristics of the electrical conductivity and thermal imaging modalities can be combined. In this experimental study, it is objected to observe whether the temperature contrast created by the tumor tissue can be improved just due to the current application within medical safety limits. Various thermal breast phantoms are developed...
متن کاملMulti-optical-wavelength ultrasound-modulated optical tomography: a phantom study.
We used multiple optical wavelengths to study ultrasound-modulated optical tomography (UOT) in tissue phantoms. By using intense acoustic bursts and a CCD camera-based speckle contrast detection technique, we observed variations of the ultrasound-modulated signal at various optical absorptions. The experimental variations were found to be highly correlated with predictions from Monte Carlo simu...
