Description: 稳健自适应波束形成，Wiley出版社，是一本有关MVDR波束形成稳健性分析的好书。-The latest research and developments in robust adaptive beamforming Recent work has made great strides toward devising robust adaptive beamformers that vastly improve signal strength against background noise and directional interference. This dynamic technology has diverse applications, including radar, sonar, acoustics, astronomy, seismology, communications, and medical imaging. There are also exciting emerging applications such as smart antennas for wireless communications, handheld ultrasound imaging systems, and directional hearing aids. Robust Adaptive Beamforming compiles the theories and work of leading researchers investigating various approaches in one comprehensive volume. Unlike previous efforts, these pioneering studies are based on theories that use an uncertainty set of the array steering vector. The researchers define their theories, explain their methodologies, and present their conclusions. Methods presented include: Coupling the standard Capon beamformers with a spher Platform: |

Description: Ultrasound Speckle Reduction Using Coded Excitation and Pulse Compression
Ultrasound images are riddled with system dependent imperfections called speckle (multiplicative noise). In ultrasonic imaging, detection of small lesions could be difficult because the effects of speckle may mask the visibility of these small targets. Therefore, the purpose of this project is to decrease speckle while maintaining some of the key salient features in the image. Images of tissue-mimicking phantoms will be created using Field II [1-2] in MATLAB (Natick, MA). Image quality metrics such as speckle signal-to-noise ratio (sSNR) [3] and contrast-to-noise ratio (CNR) [4] will be used to quantify improvements in image quality after various despeckling filters have been applied.

Description: Image processing plays a vital role in the development of medical industry especially ultrasound medical images.
Image acquisition is carried out using ultrasound equipments like transducer, scanner, and CPU and display device. There are
mainly four modes of ultrasound imaging A-mode, M-mode, B-mode and Doppler-mode. Ultrasound imaging plays crucial role in
medical imaging due to its non-invasive nature, low cost and capability of forming real time imaging. Modern ultrasound systems
are signal processing intensive. Advanced techniques of signal processing are used to provide better image quality and higher
diagnostic value. Platform: |
