Suspension type self-adjusting ultrasonic scanning probe fixing frame

Abstract

The invention discloses a suspension type self-adjusting ultrasonic scanning probe fixing frame which comprises a lower jaw corner bracket, an angle measuring bracket, a position corrector, an unlocking lock base and an unlocking lock linkage shaft. Two lower jaw corner brackets with hole grooves are symmetrically fixed at the top ends of the corresponding angle-measuring brackets; the two angle-measuring supports are fixed to the two sides of the unlocking lock base respectively, and an opening of the unlocking lock base is closed through the unlocking lock linkage shaft. According to the invention, a relatively constant distance between the mandible of a wearer and the ultrasonic scanning probe can be well ensured, so that the stability is improved; meanwhile, the wearer can adjust the angle of the ultrasonic scanning probe as required to provide a quantitative basis for researching the influence of the inclination angle on the experiment; the lower jaw corner bracket can help a wearer to reduce experimental interference brought by a tongue motion compensation mechanism due to excessive extrusion of the device on the lower jaw as much as possible; the position corrector can automatically adjust the fixing position of the ultrasonic scanning probe, and the adverse effect of human intervention on the imaging result of the ultrasonic probe is reduced.

Description

technical field [0001] The invention relates to the technical field of tongue movement ultrasonic imaging in the study of pronunciation mechanism, in particular to a suspended self-adjusting ultrasonic scanning probe fixing frame. Background technique [0002] The pronunciation system of speech includes aspects such as tuning and vocalization. Among them, tuning is used to indicate the sound produced by the combination of tongue, palate, lips, teeth and other organs in the oral cavity. With the continuous development of computer vision technology, researchers hope to provide more sufficient visual feedback for the study of pronunciation mechanism through a visualization method. [0003] Usually, researchers use ultrasound imaging technology (that is, the way of holding the imaging probe against the mandible) to study the changes in the trajectory of the tongue during the pronunciation process and the relationship between the various tissues related to it. However, affected...
