Real Time Am-fm Analysis of Ultrasound Video
نویسنده
چکیده
In this paper, we present a real-time amplitude-modulation frequency-modulation (AM-FM) analysis system, and apply the system to M-mode ultrasound video. The estimated frequency-modulation (fm) process is shown to capture the cardiac wall deformation, while the amplitude modulation process is shown to follow changes in cardiac wall material. Results from segmenting the septum and left-ventricle walk are also presented.

Fast Am-fm Demodulation Image and Video Analysis Using Single Instruction Multiple Data (simd) Architectures
AM-FM demodulation is used for expanding a digital image/video in terms of an AM-FM series expansion. The fundamental AM-FM harmonic is estimated using a collection of bandpass filters which operate over the analytic version of the input image/video. The SIMD architecture was used to develop a fast implementation of the AM-FM decomposition. Preliminary results are shown for a novel fast segment...

متن کاملEfficient Signal Processing Algorithm for Fast Optical Doppler Tomography Systems
Optical Doppler tomography (ODT) is an imaging technique which uses the Doppler shift observed in the spectrum of the backscattered light to form images of blood flow in a sample tissue. As data acquisition rates for ODT systems become greater, the need arises for a fast algorithm able to deal with increasingly short time records of the backscattered light. The objective of this paper is to pre...
