Description
Ear Nose and Throat (ENT) specialists apply flexible laryngoscopes to examine the throat. Although these flexible type of endoscopes are an important tool, hospitals do not apply standardized tests to assess the image quality of the endoscopes they use or consider to purchase. Recently we evaluated the Rez Checker Target Nano Matte, a test chart that was designed by Image Science Associates for this purpose. This test chart can be used to measure image quality in terms of sharpness, noise and colour fidelity. The purpose of this study was to explore the relationship between the subjective perceived image quality of ENT-specialists and the objectively measured sharpness, noise and colour fidelity. We assessed the subjective ranking of six types of endoscopes by imaging the larynx of one subject. The images were presented to 30 ENT-professionals for a forced pairwise comparison. The objectively measured parameters were MTF50 for sharpness, RMS for noise and CIE dE 2000 for colour fidelity. ENT-professionals ranked the sharpest endoscopes best. There was no relation found between the subjective ranking and noise or colour fidelity. Whether better image quality also improves the diagnostic accuracy of the ENT-specialist seems plausible, but still has to be established.| Period | Jan 2021 |
