A multicentre comparison of computer assisted image processing and display methods in scintigraphy

open access: closedPhysics in Medicine & Biology, 1979
Using a series of 100 brain scintigrams, 50 with single 'mathematical tumours' superimposed, a comparison is made of several processing and display methods used at various institutions in the United Kingdom. The survey compares results from seven centres and includes most types of computer generated display in current use.

A computer‐assisted image processing method for determining relative cardiac function in the chick embryo

open access: closedTeratology, 1991
AbstractThe general objective of this study was to develop a noninva‐sive method for efficiently and reproducibly determining relative cardiac function parameters in the chick embryo. The specific objectives of the study were 1) to develop several methods for computer‐assisted image processing and quan‐titation of relative intraventricular blood ...

A computer-assisted image-processing system for the analysis of autoradiographs of cerebral metabolic activity

open access: closedJournal of Medical Systems, 1980
A computerized image-processing system has been developed for quantitative analyses of the autoradiographs obtained with the [14C]deoxyglucose method. By means of this system, these cerebral metabolic images can be digitized and the resultant data can be manipulated for image construction, enhancement, enlargement, and microdensitometric analysis.

Computer-assisted image processing 12 lead ECG model to diagnose hyperkalemia

open access: closedJournal of Electrocardiology, 2016
We sought to develop an improved 12 lead ECG model to diagnose hyperkalemia by use of traditional and novel parameters.We retrospectively analyzed ECGs in consecutive hyperkalemic patients (serum potassium (K)>5.3mEq/L) by blinded investigators with normokalemic ECGs as internal controls.

Spatial characterization of contracting cardiac myocytes by computer-assisted, video-based image processing

open access: closedAmerican Journal of Physiology-Heart and Circulatory Physiology, 1996
The goals of the present study were to develop and validate a computer-assisted, video-based image processing (CAVIP) system to measure time-dependent changes in isolated myocyte geometry during contraction and to use the CAVIP system to examine spatial characteristics of the myocyte during contraction in normal myocytes and in myocytes after ...

A Desktop Image Processing System for Computer-Assisted Orthopedic Surgery (DISOS)

open access: closed, 1996
Within the framework of our research activities in orthopedic surgery a PC-based imageprocessing system for the processing of x-ray computertomographic data has been developed. The system is used as a work platform for the investigations concerning interaction modalities, strategies and techniques for an efficient planning and execution of surgical ...

Mossy fiber sprouting in the fascia dentata after unilateral entorhinal lesions: Quantitative analysis using computer-assisted image processing

open access: closedNeuroscience, 1984
Axon sprouting typically occurs in a brain region that has been partially denervated. The present study demonstrates, quantitatively, evidence for sprouting outside the region of deafferentation. A modification of the Timm sulfide silver histochemical method was used to monitor an increase in the mossy fiber terminal field in the fascia dentata of ...
