Computer-assisted quantification and image processing of whole-body autoradiograms

Journal of Pharmacological Methods, 1990
A computerized image-processing system especially adapted for analysis of whole-body autoradiograms has been developed. It consists of commercially available standard components, including a black-and-white video camera, a microcomputer, and graphics equipment.

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

Physics 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.

An intercomparison of computer assisted image processing and display methods in liver scintigraphy

Physics in Medicine & Biology, 1979
A previous study (ibid., vol.24, p.547 (1979)) has assessed processing and display methods used in scintigraphy by superimposing 'mathematical tumours' onto clinically normal brain scintigrams. In this paper the technique is applied to liver scintigraphy and a selection of techniques assessed.

Computer-assisted image processing technique for tracking wound progress

2016 IEEE International Conference on Electro Information Technology (EIT), 2016
The purpose of this study was to develop an algorithm to support the decisions of expert physicians in the management of wound healing. The goal was to work towards the development of an image processing algorithm for quantifying the progress of healing of skin wounds. For this algorithm development, multiple wound images were obtained from patients in

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

Journal 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

Journal of Electrocardiology, 2017
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.

An objective method to measure cell survival by computer-assisted image processing of numeric images of Petri dishes

Physics in Medicine and Biology, 2003
This work establishes an objective method to measure cell clonogenic survival by computer-assisted image processing using images of cell cultures fixed and stained in Petri dishes. The procedure, developed by Samba Technologies, consists of acquiring Petri dish pictures with a desktop scanner and analysing them by computer, using algorithms based on ...

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

Teratology, 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 ...

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

American 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 ...
