Context and Motivations
Tracheal and subglottic stenosis are an abnormal narrowing or contraction of the airways. They significantly reduce the air available for patients and are treated using surgery. The airflow resistance is proportional to where D is the diameter of the opening. A small reduction in the diameter could have a dramatic impact on the patient’s ability to breath.
Nowadays, ENT surgeons have no solutions for measuring the diameter of stenosis. Physicians use catheters with different diameters that harm the patient.
A prototype has been developed in the BEAMS department. This project is being developed in the context of the creation of a spin-off company.
The device is made of a fixed station and a probe. The probe (see Fig 1) is inserted in the patient and the fixed station stays in the endoscopy room. The probe contains optical parts such as a lens, a fiber laser and a diffractive optical element. The fixed station contains the hardware: the computer and the laser source.
Aim of the Project
The aim of this project is to improve the light source and integrate it into the fixed station.
In particular, the use of other sources of different wavelenghts should be investigated and testedSince this project is confidential, do not hesitate to contact mpetre [at] ulb [dot] ac.be for more information
