Evaluation Methods for Medical Endoscope's Characteristics

Abstract:

Medical endoscopes have gained widespread applications in minimally invasive surgery. There are increasing needs to accurately evaluate their performance characteristics which are beneficial to the product design, manufacture, repair and supervision. This paper gives a review of the measurement methods for the imaging and photometric characteristics of the endoscopes, such as resolution, modulation transfer function, light loss, illumination uniformity, which are very important for the evaluation of the image quality. In actual measurement, the verification of a test device itself and the uncertainty assessment or error analysis of the measurement results are also very necessary from the view point of metrology.
