Ultrasound-Guided Breath-Compensation in Single-Element Photoacoustic Imaging for Three-Dimensional Whole-Body Images of Mice
نویسندگان
چکیده
Photoacoustic imaging can be used to extract functional information at the molecular level for whole body of small animals in vivo . However, use a mechanical scanner image involves acquiring data period time which lead breathing-related artifacts. Thus, acquired three-dimensional cannot analyzed and visualized using two-dimensional projection rendering techniques unless respiratory distortions are minimized. In this study, an ultrasound-guided breath-compensation method photoacoustic macroscopy facilitate visualization analysis depth direction is presented. ultrasound mice were , then distorted skin layers compensated data. The extracted distortion parameters applied corresponding compensate motion. compensation was successfully visualize hemoglobin oxygen saturation by multispectral resulting images show that developed methodology various biomedical studies, including monitoring drug delivery, tumors, vasculature networks.

Compensation of Ultrasound Attenuation in Photoacoustic Imaging
Photoacoustic imaging is a non-destructive method to obtain information about the distribution of optically absorbing structures inside a semitransparent medium. It is based on thermoelastic generation of ultrasonic waves by the absorption of a short laser pulse inside the sample. From the ultrasonic waves measured outside the object, the interior distribution of absorbed energy is reconstructe...
متن کاملWhole Body Three Dimensional Plaque Imaging
Introduction Atherosclerosis is a systemic disease. Angiographic approaches are “luminograms” and provide no data on vascular remodeling and plaque burden which are far more important determinants of risk in vascular diseases. Assessment of overall plaque burden with current 2D MRI approaches [1-3] has important limitations. Firstly, imaging is limited to selective anatomical regions (e.g., car...

The objective of this article is to provide scientists, engineers and clinicians with an up-to-date overview on the current state of development in the area of three-dimensional ultrasound (3-DUS) and to serve as a reference for individuals who wish to learn more about 3-DUS imaging. The sections will review the state of the art with respect to 3-DUS imaging, methods of data acquisition, analys...
متن کاملThree-dimensional ultrasound imaging.
Two-dimensional viewing of three-dimensional anatomy by conventional ultrasound limits our ability to quantify and visualize a number of diseases and is partly responsible for the reported variability in diagnosis. Over the past two decades, many investigators have addressed this limitation by developing three-dimensional imaging techniques, including three-dimensional ultrasound imaging. In th...
متن کاملThree dimensional motion compensation for real-time MRI guided focused ultrasound treatment of abdominal organs
Purpose/Introduction MR-guided High Intensity Focused Ultrasound (HIFU) for the ablation of tumors in abdominal organs under freebreathing conditions poses two challenges: 1) The current organ position in 3D-space must be continuously tracked in order to reposition the focal point of the HIFU-device to avoid undesired tissue damage. 2) Phase variations due to the organ displacement must be corr...
