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

Trends in Neurosciences, 1983 Abstract The application of computers to recently developed autoradiographic methods for studying a variety of brain processes has greatly facilitated and expanded the use of these methods. Computer-assisted image-processing systems make feasible the extraction of information from autoradiographs which is not readily accessible by manual means and the

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 ...

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.

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.

Acta Odontologica Scandinavica, 1995 The purpose of this study was to evaluate a method for computer-assisted image processing to assess quantitatively fractional bone volume in sections of bone biopsies (part I). A second purpose was to apply this method in an experimental study to determine bone loss by measuring fractional bone area in sections of calvarial bone of gastrectomized rats ...

<title>Computer-assisted image processing for lung cancer localization</title>
SPIE Proceedings, 1996 Autofluorescence of the tumor and surrounding tissue is the largest background source in fluorescence diagnosis. A new system which applied computer image processing technique to lung cancer localization by laser fluorescence bronchoscopy has been developed to subtract the autofluorescence background.

Journal of Neuroscience Methods, 1984 A general purpose image processing system is described including B/W TV camera, high resolution image processor and display system (TESAK VDC 501), computer (DEC PDP 11/23), and monochrome and color monitors. Images may be acquired from a microscope equipped with a TV camera or using the TV in direct viewing; the A/D converter and the image processor ...

Computer-assisted image processing 12 lead ECG model to diagnose hyperkalemia
Journal of Electrocardiology, 2017We 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.
