Book excerpt: The presence of a high level of noise is a characteristic in some tomographic imaging techniques such as positron emission tomography (PET). Wavelet methods can smooth out noise while preserving significant features of images. Mallat et al. proposed a wavelet based denoising scheme exploiting wavelet modulus maxima, but the scheme is sensitive to noise. In this study, the authors explore the properties of wavelet phase, with a focus on reconstruction of emission tomography images. Specifically, they show that the wavelet phase of regular Poisson noise under a Haar-type wavelet transform converges in distribution to a random variable uniformly distributed on [0, 2[pi]). They then propose three wavelet-phase-based denoising schemes which exploit this property: edge tracking, local phase variance thresholding, and scale phase variation thresholding. Some numerical results are also presented. The numerical experiments indicate that wavelet phase techniques show promise for wavelet based denoising methods.

Book excerpt: Terahertz biomedical imaging has become an area of interest due to its ability to simultaneously acquire both image and spectral information. Terahertz imaging systems are being commercialized, with increasing trials performed in a biomedical setting. As a result, advanced digital image processing algorithms are needed to assist screening, diagnosis, and treatment. "Pattern Recognition and Tomographic Reconstruction" presents these necessary algorithms, which will play a critical role in the accurate detection of abnormalities present in biomedical imaging. Terhazertz tomographic imaging and detection technology contributes to the ability to identify opaque objects with clear boundaries, and would be useful to both in vivo and ex vivo environments, making this book a must-read for anyone in the field of biomedical engineering and digital imaging.

Available in PDF, EPUB and Kindle. Book excerpt: Over recent years there has been a vast expansion in the variety of imaging techniques available, and developments in machine specifications continue apace. If radiologists and radiographers are to obtain optimal image quality while minimising exposure times, a good understanding of the fundamentals of the radiological science underpinning diagnostic imaging is essential. The second edition of this well-received textbook continues to cover all technical aspects of diagnostic radiology, and remains an ideal companion during examination preparation and beyond. The content includes a review of basic science aspects of imaging, followed by a detailed explanation of radiological sciences, conventional x-ray image formation and other imaging techniques. The enormous technical advances in computed tomography, including multislice acquisition and 3D image reconstruction, digital imaging in the form of image plate and direct radiography, magnetic resonance imaging, colour flow imaging in ultrasound and positron radiopharmaceuticals in nuclear medicine, are all considered here. A chapter devoted to computers in radiology considers advances in radiology information systems and computer applications in image storage and communication systems. The text concludes with a series of general topics relating to diagnostic imaging. The content has been revised and updated throughout to ensure it remains in line with the Fellowship of the Royal College of Radiologists (FRCR) examination, while European and American perspectives on technology, guidelines and regulations ensure international relevance.

Available in PDF, EPUB and Kindle. Book excerpt: One of the most significant features of diagnostic echocardiographic images is to reduce speckle noise and make better image quality In this paper ve proposed a simple and effective filter design for image denoising and contrast enhancement based on multiscale wavelet denoising method, Wavelet threshold algorithms replace wavelet coefficients with small magnitude by zero and keep or shrink the other coefficients, This is basically a local procedure since wavelet coefficients characterize the local regularity of a function, After ve estimate distribution of noise within echocardiographic image then apply to fitness Wavelet threshold algorithm. A common way of the estimating the speckle noise level in coherent imaging is to calculate the mean-to-standard-deviation ratio of the pixel intensity often termed the Equivalent Number of Looks(ENL) over a uniform image area, Unfortunately we found this measure not very robust mainly because of the difficulty to identify a uniform area in a real image. For this reason we will only use here the S/MSE ratio and which corresponds to the standard SNR in case of additive noise. We have simulated some echocardiographic images by specialized hardware for real-time application; processing of a 5125̂12 images takes about 1 minute. Our experiments show flat the optimal threshold level depends on the spectral content of the image. high spectral Content tends to over-estimate the noise standard deviation estimation performed at the finest level of the DWT. As a result a lower threshold parameter is required to get the optimal S/MSE. The standard WCS theory predicts a threshold flat depends on the number of signal samples only.
