The invention relates to a molded gel body (1), the production thereof and the use thereof in ultrasonography in the medical or dental field. In particular, the molded gel body (1) is used to detect and localize dental cavities in the jawbone by means of through-transmission alveolar ultrasonography (TAU). The molded gel body (1) has a receptacle (2) for receiving an ultrasound transmitter and/or receiver (7). The molded gel body (1) and the receptacle (2) are preferably adapted to the shape of the ultrasound transmitter and/or receiver. For easier handling, the molded gel body (1) is inserted into a flexible, biocompatible protective cover (6) which, like the receptacle (2), can be filled with a non-dimensionally stable ultrasound gel. To produce the molded gel body (1), cuboids of a dimensionally stable gel of the appropriate size are preferably cut open over the narrow lateral surfaces of the cuboid, but preferably not completely cut through and only over three of the four sides to produce the receptacle (2) or, if not completely cut open, closed or glued on the edges only over two of the four sides.

Specialized ultrasound imaging systems and methods provide metrics related to objective and consistent quantification of scar tissue volume that strongly correlate with tendon healing and range of motion. Automated acquisition of ultrasound images of fingers helps assess tendon healing in a non-invasive, quantitative fashion and can be used to guide clinical decision-making, management of post-operative tendon repair patients, and employment and insurance considerations.
