    In this paper, a new method is developed for obtaining an X-ray reconstruction of the soft tissue detail of the spinal canal. By removing the dominant effects of the bony vertebral body within the projection actual clinical data, higher quality images of the residual soft tissues components can be reconstructed. The intent is a direct visualization of the spinal cord without the need for water-sol... View full abstract»

    The relationship between peak isovolumic developed pressure (Pmax) and end-diastolic volume can indicate ventricular contractility. Therefore, we propose a practical method to estimate Pmax from the pressure curve of an ejecting contraction of left ventricle. For the estimation, we first considered the left ventricle a linear time varying hydromotive pressure source (HMP(t)) coupled in series with... View full abstract»

    The control of contractions elicited by electrical stimulation of muscle could be improved if there was a linear repeatable input-output relationship. The input is the command to the controlled stimulator and the output is the evoked contraction. Systems employing closed-loop force feedback to provide regulation of contractions were investigated in these studies. Force was modulated by both recrui... View full abstract»

    Certain diffuse liver diseases, such as hepatitis and cirrhosis, are difficult to diagnose from the information contained in ultrasound images. A signal processing procedure is described which estimated the value of an acoustic attenuation coefficient of the liver in vivo from reflected ultrasound signals. The results of a clinical trial involving 14 patients indicate a correlation between the coe... View full abstract»

    We introduce a new approach to the quantification of myocardial strain. It utilizes the theoretical frame work of kinematics and can thus account for the large time-varying displacements present in the intact beating heart. For arbitrary small segments of myocardium, we show how these displacements can be described completely by a rotation tensor and a stretch tensor. We demonstrate the physiologi...

    Bubbles that form in the tissues and bloodstreams of animals and humans undergoing a compression/decompression sequence are considered precursors to symptoms of decompression sickness. A prevalent method used to monitor these bubbles is to ensonify the pulmonary artery or inferior vena cava with ultrasound and listen for Doppler shifted signals in the reflected and scattered sound.

  • Implementing a Consistency Criterion in Numerical Solution of the Bioelectric Forward Problem

    The bioelectric forward problem is frequently formulated as an integral equation that relates unknown surface potentials with their known current generators, in a given volume conductor. The matrix of the discretized equations is singular, and this may cause difficulties in obtaining a numerical solution to the problem. A consistency criterion for the discretized equations is utilized in a new alg... View full abstract»

  • Conversion Errors in 4-Bit Flash Analog-to-Digital Converters

    Publication Year: 1980, Page(s):341 - 343
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (366 KB)

    Conversion errors in 4-bit flash analog-to-digital converters are computed from difference equations as a function of the ratio of the comparator input impedance to the R-2R bias network values. For maximum conversion errors less than 3 percent, the comparator input impedance should be 1000 times greater than the R value of the bias network. View full abstract»
