The objective of this project is to develop a device that allows a physician to view and measure real time lung motion of a patient inside a CT scanner during lung biopsy. This will increase time efficiency and accuracy of lung tumor treatment CT procedures, as this device will enable the collection of clear and meaningful scans. With this application, size and simplicity are of the utmost importance, as the device must be as practical as possible. Given these constraints the design involves a low profile, low volume sensor to measure data while physically attached to the patient’s bed, and a computer base station graphical user interface which receives the data wirelessly. The interface of this base station, as viewed by the physician, displays a live graph of the lung displacement - accurate within 0.18 ms and 2 mm. This device will not only allow doctors to biopsy lung lesions more efficiently, but will also reduce radiation exposure to the patient by avoiding repeated scans. The device will work in tandem with the CT scan; the device triggering the scan to be taken when the patient’s lungs are held in the desired position. This procedure will help to minimize healthy tissue damage and to streamline the treatment process by reducing the amount of X-ray scans needed, thus positively impacting patient recovery time and overall process effectiveness.
