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)
Recent reports have shown that responses of midbrain neurons in the guinea pig rapidly shift the dynamic range of their responses to track changes in the statistics of ongoing sound-level distributions. This results in an increased coding accuracy for the most commonly occurring stimulus intensities. To investigate whether this type of adaptation might also(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)
