Abstract

BLOOD FLOW IN BLOOD VESSELS IS CHARACTERISED BY THE MOVEMENT IN ‘TRAINS’. THE APPARATUS AND METHOD OF THE PRESENT INVENTION IS TO DEVELOP A NON-INVASIVE AND ACCURATE TECHNIQUE FOR MEASURING BLOOD FLOW, IN THE FORM OF A TRAIN IN VISIBLE BLOOD VESSELS, TO DETERMINE THE FLOW SPEED AND OTHER BLOOD CHARACTERISTICS BY PERFORMING VISUAL IMAGE ANALYTICS. THE PRESENT INVENTION COMPRISING AT LEAST ONE PRIMARY (106) AND SECONDARY IMAGE MODULE (1 1 0) TO IMAGE BLOOD ‘TRAINS’ CONNECTING TO AT LEAST ONE PROCESSING DEVICE (104); AND AT LEAST ONE OBJECT OF INTEREST THAT IS BEING STUDIED. THE PRESENT INVENTION UTILIZES A CAMERA TO IMAGE BLOOD ‘TRAINS’ (GROUP OF BLOOD FLOWING SEPARATELY). THE METHODOLOGY OF THE PRESENT INVENTION PROVIDES FOR MEASUREMENT OF LENGTH AND WIDTH OF THE BLOOD TRAIN FROM THE IMAGE WHILE THE VOLUME OF THE. BLOOD TRAIN IS DETERMINED USING WIDTH TO DETERMINE THE CIRCUMFERENCE AND MULTIPLYING IT WITH THE LENGTH OF THE BLOOD TRAIN. THEWIDTH IS MEASURED BY SELECTING A CROSS-SECTION LINE OF A NUMBER OF PIXELS (E.G. 5 PIXELS) THICKNESS FOR COLOUR VARIATION OF THE SELECTED OF THE AREA. THE PIXEL VALUES ARE MEASURED AGAINST THE SIMILAR NEIGHBOURING GROUP OF PIXELS TO ASCERTAIN THE COLOUR CHANGE BETWEEN THE PIXELS. IF THE VALUES ARE CONSTANT, THE COLOUR IS CONSISTENT AND IF THE VALUE IS HIGH, THE DIFFERENCE WILL SHOW A CHANGE FROM RED HUES (THE BLOOD VESSEL) TO A LIGHTER COLOUR (THE SURROUNDING FAT) AND VICE-VERSA. FROM THE WIDTH (THE DIAMETER), CIRCUMFERENCE IS DEDUCED AND BY MULTIPLYING THIS WITH THE LENGTH, THE TOTAL VOLUME CAN BE CALCULATED. MEASUREMENT OF SPEED IS ALLOWED AS THE INITIAL START AND END OF A BLOOD TRAIN IS USED TO MEASURE THE TIME TAKEN TO TRAVEL OVER A LENGTH OF THE BLOOD CAPILLARY. (THE MOST ILLUSTRATIVE DRAWING IS
