Study of venous wall behaviour for early diagnosis of deep vein thrombosis (DVT)

| Ringkasan: | Deep Vein DVT occurs when a deep vein is partially or completely blocked by a blood clot, most commonly in the legs. It can sometimes be difficult to recognize the symptoms of DVT. However, the condition can be effectively treated once it been diagnosed but too little attention has been paid to methods of early prevention of the disease. Thus, the objective of this study is to diagnose the early stage of DVT by studying the effects venous wall displacement to the valvular insufficiency In this project, the experimental programme is conducted on 3 subjects with no history of DVT to define the normal range of diameters in the deep veins of the thigh via ultrasound image processing method. First part of the method is to come up with image processing algorithm such as contrast enhancement and filtering to tracking the venous wall. Second part is analysing the image to define the wall displacement. Two methods had been approached; one using point to point method with 6.5% errors and the second is by using image subtraction with 22.06% errors. |
