Research project: Detection and quantification of arterial obstruction in acute pulmonary embolism

Abstract

A pulmonary embolism (PE) is an obstruction within the pulmonary arterial tree that in the majority of cases arises from a thrombosis that has travelled to the lungs via the venous system. PE is a fatal condition that affects all age groups and is the third most common cause of death in the US. Computed tomographic angiography (CTA) is an accurate imaging technology widely used in the diagnosis of pulmonary embolism. However, each CTA scan contains hundreds of CT image slices, and the accuracy and efficiency of interpreting such a large image data set using manual reading and interpretation is time-consuming and prone to error due to the ambiguous appearance of PE-like structures and human factors such as attention span and eye fatigue. Consequently, objective methods of computer-assisted image analysis based on computer aided detection (CAD) and measurement (CAM) can be applied effectively to assist radiologists in detecting and characterizing emboli in an accurate, efficient and reproducible manner. The aim of this project is to develop 3D image processing algorithms:

1. To detect and segment pulmonary arteries and label its major branches

2. To detect, locate and characterise pulmonary embolism within each branch

3. To define and evaluate a specific index to quantify arterial obstruction in acute pulmonary embolism.

Biography

I was a volunteer as a paramedic and social worker in the Lebanese Red cross before and during my bachelors degree. I quit to continue my masters in London.

After my Masters degree I worked in Nigeria as a technical manager in a biomedical company (Tanit Medical Engineering company Nig), installing and performing corrective and preventive maintenance on medical equipment. 

Then I changed work and got a Job  as a biomedical engineer at Jetgate engineering Nigeria, in which I promoted new technologies and installed them. I was then promoted to a director in the company setting and reaching company goals.

As I was director I had the chance to work as a part-timer at a start up medical-company (troment Nigeria) as a project manager / administrative director. 

I then left Nigeria, and after a little while started my PhD. 

I am now teaching part-time at Lebanese German University in Lebanon
