Doan Trang Nguyen 

I am a PhD student at CARLab. My main interest is in biomedical engineering especially in the fields of bioelectronics, medical signals and image processing. 

Research

My PhD research aims at producing both hardware and software of a complete Electrical Impedance Tomography (EIT) system, which will be capable of mapping perfusion in both the lung and the heart. Combining this with traditional pulmonary ventilation EIT, the resulting system will be able to map both ventilation and perfusion distribution, which would give a unique insight into lung physiology and pathophysiology. This system can be used to monitor and validate new ventilation strategies, supportive therapies in acute respiratory failure and lung embolism. Furthermore, the cardiac perfusion component of the work can be used to monitor cardiac activities and diagnosis of heart failure. Currently, the assessment of cardiac function and pulmonary perfusion in critically unwell patients are two important problems that do not have satisfactory solutions. The following techniques will be explored in this project:

  •   improve the spatial resolution of EIT,

  • improve signal separation between ventilation, perfusion and cardiac mechanical actions for regional perfusion EIT in different parts of the lung,

  •  apply the techniques for lung perfusion imaging to cardiac perfusion imaging for studies on cardiac tissues.
