BACKGROUND Atherosclerotic plaque stability is related to histological composition. However, current diagnostic tools do not allow adequate in vivo identification and characterization of plaques. Spectral analysis of backscattered intravascular ultrasound (IVUS) data has potential for real-time in vivo plaque classification. METHODS AND RESULTS(More)
Spherically focused, high frequency (30-50 MHz) ultrasonic imaging transducers are fabricated by using a piezoelectric polymer film and membrane deflection technique that is compatible with CMOS circuit fabrication. Micromachined ultrasonic transducers with 0.5-2.0 mm-diameter apertures and f-numbers ranging from 1.3-4.0 are fabricated and characterized.(More)
Automatic Sign Language Recognition is an extensive research area in the field of human computer interaction. Such recognition systems are meant to replace sign language interpreters. With the development of image processing and artificial intelligence techniques, many techniques have been recently developed in this area. Most of the signs in Indian Sign(More)
AIMS The objectives of the present study are to describe the algorithm for VH(®) IVUS using the 45-MHz rotational IVUS catheter and the associated ex vivo validation in comparison to the gold standard histology. METHODS AND RESULTS The first phase of the present study was to construct the 45 MHz VH IVUS algorithm by using a total of 55 human coronary(More)
