Non-invasive ultrasonic gingival tissue diagnosis

摘要

Disclosed are various embodiments for echoperiodontal imaging. In one embodiment, a system includes a transducer configured to transmit a series of ultrasonic signals at a plurality of corresponding locations along soft tissue of a jaw and receive a plurality of echo signals; and an imaging system controller configured to obtain a plurality of echo signal data of the soft tissue and a plurality of transducer positions, where each echo signal data corresponds to one of the plurality of transducer position.

1. A system for echoperiodontal imaging of gingival tissue, comprising:
a transducer adapted to:
be positioned along a plurality of locations of gingival tissue for a region of interest of a jaw;transmit a series of ultrasonic signals at the plurality of locations of the gingival tissue for the region of interest of the jaw, andreceive a plurality of echo signals, each echo signal corresponding to one of the transmitted ultrasonic signals at one of the plurality of locations of the gingival tissue; and imaging system computer hardware configured to:
coordinate transmission of the series of ultrasonic signals and reception of the corresponding echo signals,obtain a plurality of echo signal data of the gingival tissue and a plurality of transducer positions, where each echo signal data corresponds to one of the plurality of transducer positions and is derived from the received plurality of echo signals;dividing a region of interest in the echo signals of the plurality of corresponding locations into a plurality of two-dimensional kernels comprising sub-regions of the region of interest;convert each of the plurality of two-dimensional kernels into a plurality of one-dimensional signal vectors from neighborhood pixels within a two-dimensional kernel and the one-dimensional signal vectors are used to extract parametric values in a time-domain, a frequency-domain, and a wavelet-domain; andreconstruct at least a two-dimensional image of a portion of the gingival tissue of the jaw based upon the obtained echo signal data, the plurality of transducer positions, and the parametric values from at least the time-domain, the frequency-domain, and the wavelet-domain, wherein the at least a two-dimensional image comprises a parametric ultrasound image with pixel values represented using the parametric values from the time-domain, the frequency-domain, and the wavelet-domain.
