Ultrasound imaging plays an important role in oncological imaging for more than five decades now. It can be applied in all tissues that are not occluded by bone or gas-filled regions. The quality of ultrasound images benefitted strongly from improved electronics and increased computational power. To the morphological imaging, several functional imaging

Pseudocoloring of ultrasound images
2017 25th Signal Processing and Communications Applications Conference (SIU), 2017Human visual system detects details in coloured images better. Sometimes interpretation of details in gray scale ultrasound images becomes harder. So in this work pseudocoloring of ultrasound images using empirical mode decomposition (EMD) is proposed. EMD doesn't use base function so it has more advantages than Fourier and wavelet transforms.

Image enhancement in ultrasound imaging
2016 24th Signal Processing and Communication Application Conference (SIU), 2016In this paper, two different methods are suggested in order to provide image enhancement in ultrasonic B-mode imaging. By obtaining RF data from two different phantom used to form B-mode image, their spectral characteristics were observed. Then by forming RF envelope from obtained data, conversion of envelope to color image is provided.

Modern ultrasonic transducers mainly employ lead zirconate titanate (PZT) but vinylidene fluoride trifluoroethylene copolymer (P (VDF-TrPE)) is becoming more competitive. The static scanner is now largely replaced by mechanical or electronically controlled array real time systems; the speed of scanning is limited by the speed of sound and the ...

Recent developments in the surgical and oncological management of breast cancer and the understanding of the complex genetic basis of the disease have been paralleled by advances in breast imaging. Breast ultrasound (US) has a key role in the assessment of breast disease, together with mammography, clinical examination and needle biopsy.

Superresolution in ultrasound imaging
2009 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2009Ultrasound techniques for imaging objects significantly smaller than the source wavelength are investigated. The present overview explains two such methods that are being investigated in our laboratory. The first method is designed for detecting scattering using an unfocused ultrasound field created from a continuously-driven source array.

Ultrasound imaging in spondyloarthropathies
Best Practice & Research Clinical Rheumatology, 2010Through recent technological advances, ultrasound allows high-resolution visualisation of inflammatory and destructive changes in tendon and joint structures. Over the last few years, the added value of the use of ultrasound for evaluating entheseal involvement in spondyloarthritis (SpA) patients has been demonstrated.

Cerebrovascular Ultrasound Imaging
Radiologic Clinics of North America, 1988Advancements in technology have brought noninvasive diagnosis of cerebrovascular disease to a high level of accuracy in a relatively short period of time. Conventional duplex sonography allows precise vessel localization and Doppler quantification. The further refinement of color flow imaging promises to simplify the examination and add considerable ...
