Major limitations of these techniques are a rather high error, a low time resolution, the limitation to certain experimental conditions and, possibly, photo dama

The results of the study demonstrate that there are several experimental techniques that can be used for precise quantitative evaluation of the tissues local mec

Finally, results of the algorithm implemented using MATLAB and C/C++ and the respective images are presented

Assuming a receiving transducer and a transmitting transducer separately, the present system is improved to get high signal to noise ratios even at high frequencies by using a broadband transducer made from polymer piezoelectric materials particularly for the reception. Two transducers are u

At certain frequencies the magnitude image of an object consisting of materials of different densities may not provide sufficient contrast to distinguish each of the materials from one another so the phase of vibration is assessed as another modality for contrast. An experiment is

The method has been validated in nasal cavity models with known dimensions, and in humans and animals, where the dimensions were measured by other methods as well, (CT-scanning, MR scanning and fluid di
