the application of magnetic resonance to diagnostic medical imaging stands as one of the great scientific achievements in the past 50 years. magnetic resonance techniques are easily applied to organs which remain stationary during the imaging procedure, such as the brain and musculoskeletal system. imaging of moving heart structures and circulating blood is considerably more difficult.   clinic...

The average velocity of water flow has been simultaneously measured with fluorescent and speckle imaging methods. The measured velocities with two methods are in good agreement with each other and it confirms that the speckle imaging method can be used as a confident method to measure the velocity of water flow in a dry leaf. Also the velocity of water flow through thick and thin xylems of a le...

Introduction: The limited spatial resolution of the gamma camera hinders the absolute quantification of planar images of small structures. The imaged structures are affected by partial volume effects (PVEs), which can spread activity and lead to underestimation of the regional distribution.  The use of optimum planar parameters reduces the impact of the limited spatial resolution of the gamma c...

Flow imaging is an important method for quantification in many medical imaging modalities, with applications ranging from estimating wall shear rate to detecting angiogenesis. Modalities like ultrasound and optical coherence tomography both offer flow imaging capabilities, but suffer from low contrast to red blood cells and are sensitive to clutter artefacts. Photoacoustic imaging (PAI) is a re...

In this work, we have developed the glass‐based capacitive micromachined ultrasound transducers (G‐CMUTs). The sacrificial layer etching process flow employed for manufacturing of G‐CMUTs is reported. Specific has significant promise acoustic property with ~130 % bandwidth at ~8.2 MHz. Real time in‐vivo imaging capability demonstrates actual usability technology medical imaging.

medical imaging has a remarkable role in the practice of clinical medicine. this study intends to evaluate the knowledge of indications of five common medical imaging modalities and estimation of the imposed cost of their non-indicated requests among medical students who attend shiraz university of medical sciences, shiraz, iran. we conducted across-sectional survey using a self-administered qu...
