Streszczenie angielskie:
The present work estimates the use of ultrasound to determine the size of local injuries in the rabbit lower jaw. The injuries were modelled in vitro by a various number of splits of the various depth, made on the lower edge of the jaw by dental split-dusc. Ultrasonic immaging and evaluation of effective velocity of ultrasound propagation across the injury was made to estimate the size of the injury. Measurements were performed on the phantom, made from bone, covered with soft tissue. Measurements of the effective velocity were made for uncovered bone, as well. Propagation velocity decreased when the total injury volume increased, both in the open bone, and the bone, covered with soft tissue, in the latter case the variation of propagation velocity being smaller. This fact may be used to evaluate the injury size in vivo.
