A miniature device aiming for long-term surveillance of nasopharynx cancer

Abstract

In this paper, we proposed a wireless and miniature device for long-term surveillance for nasopharynx cancer. The device was composed with Φ3.5mm diameter mini-camera, 2.4GHz wireless emitter and rechargeable 80mAh lithium-ion battery. The miniature camera was attached on the surface of the vomer bone. The captured image from the device was performed with sobel edge detection algorithm to extract the contour of artificial marker. The validity of the proposed device was assessed by the present experiment.
