Comparison of performance and characteristics of these cavities was carried out to investigate the influences of the cavity geometry, detection aperture position and geometry, aiming to optimize the design and capability of TE111 cavity for in vivo tooth dosimetry. The characteristics of the cavities were evaluated by finite elements calculation, DPPH sample measurement and intact tooth measurement. The results suggested that (1) expanded geometry of the aperture made it easier for teeth biting into the aperture; (2) the detection aperture position and size could introduce obvious influence to resonant quality factor Q; (3) the cavity dimension influenced the resonant factor Q, microwave distribution and in vivo detection implement; (4) lower diameter-height ratio brought more convenience for placement in inner oral. These results provided the references for future TE111 mode cavity design in aperture and cavity geometry.
