The importance of ultrasonic side-lobe artifacts.
Transducer side lobes consist of multiple low-intensity sound beams located outside of the main ultrasound beam. Although the echoes generated by side lobes originate outside of the main beam, they appear as specular or diffuse artifactual echoes within the beam. They are visible with both static and real-time equipment. Specular side-lobe artifacts occur near strong, curved, highly reflecting ...
متن کاملSide Lobe Suppression Based on Optimized Phase Rotation Sequence
This paper proposes an optimized phase rotation sequence method for side lobe suppression by complementing and regulating the side lobe suppression sequence set. The sequence set is efficiently enhanced through the quadratically constrained least square model. The theoretical suppression performance of our method is discussed. Furthermore, our scheme is also suitable for cognitive radio, which ...
متن کاملA new approach to medical image stitching using minimum average correlation energy filter and peak to side-lobe ratio
Medical imaging is an important tool in healthcare services for diagnosis, planning, executing, and evaluating surgical and therapeutical procedures. X-rays are the oldest and most frequently used form of medical imaging. Imaging with X-rays involves disclosing a part of the body to a small amount of ionizing radiation to produce images of the inside of the body or part of it (Maintz et al., 19...
متن کاملPrinted Antenna Arrays with High Side Lobe Suppression: the Challenge of Design
The design of printed antenna arrays with high side lobe suppression has been analysed in this article. The parallel, perpendicular and corner reflectors have been investigated. The arrays are with symmetrical pentagonal dipoles as radiating elements operating at a second resonance. The symmetrical tapered feed network, which consists of impedance transformers, with Dolph-Chebyshev distribution...
متن کاملAn adaptive speckle suppression filter for medical ultrasonic imaging
An adaptive smoothing technique for speckle suppression in medical B-scan ultrasonic imaging is presented. The technique is based on filtering with appropriately shaped and sized local kernels. For each image pixel, a filtering kernel, which fits to the local homogeneous region containing the processed pixel, is obtained through a local statistics based region growing technique. The performance...
