A true color digital image processing technique has been developed to search for specified colors in a medical image for quantification of areas of interest. The technique is clinically being used on microscopic fluorochromic bone biopsy images to quantify new bone growth. Based on a user supplied training set, a multispectral classification of pixel values is performed and used for segmenting the...
To diagnose cervical cancer from biopsies, digital image analysis techniques and statistical discriminant analysis are use to identify mitotic cells, which are a marker of early cancer. Parameters extracted from each cell include areal and geometrical measures, optical density statistics, bending energy, and various statistical texture features. The discriminant analysis attempts to classify mitotic...
A system developed on a PC and a VAX host automatically acquires clinical images and patient data from a standard ultrasound unit and transfers them to a digital picture archiving and communications system (PACS) network for storage and display. Normal clinical exam procedures are observed and the digital system is user transparent. The PACS uses an Ethernet network, optical-disk storage and multiple-image...
