The CT scan medical imaging requires huge amount of computations for reconstructing the images. Modified Fast Radon Transform (MFRT) uses FFT based parallel algorithm for reconstruction of 2D/3D CT images from its sonogram data using convolution operation by concurrent 1D FFT/IFFT and matrix multiplications. To achieve optimum hardware utilization with low power consumption an FFT module, based on...
Diabetes is a disease of concern, which affects vital organs of body. In order to prevent complications, frequent glucose measurement is necessary. This paper presents a possible methodology for noninvasive blood glucose measurement using photoacoustic (PA) method. Although encouraging results have been obtained using the developed system, certain other error sources like melanin content of skin,...
In this paper, we present an intelligent approach to analysing prostrate ultrasound images in order to diagnose prostate cancer. Algorithms based on fuzzy image processing are applied first to enhance the contrast of the original image, to extract the region of interest and to enhance the edges surrounding that region. Then, we extract features characterising the underlying texture of the regions...
Ultrasound imaging systems use a scan conversion process to display data acquired with polar coordinate in Cartesian coordinate system. To avoid artifacts interpolation is needed for unsampled pixels. The resultant image quality is dependent on the interpolation algorithm. Majority of the interpolation mechanisms enhance both smooth and detailed regions which degrades the image quality. In this paper,...
This paper presents a novel approach for speckle reduction of ultrasound image and its implementation using EDK 7.1i (Embedded Development Kit) on ML310 embedded development platform wherein the image is read from an image data file to a set of slave registers in the filter core through the On-Chip Peripheral Bus (OPB) and thereby processed in the filter core. Speckle is a phenomenon in ultrasonic...
Ultrasound images are masked by multiplicative speckle noise caused by random interference between coherent backscattered waves. This paper presents an efficient algorithm for real-time speckle cleaning filter of ultrasound images and its VLSI implementation in FPGA. The algorithm presented here implements a regular, tunable filter with an optimized architecture having proper parallelism and pipelining...
