Methods for Measuring Phase Dynamics and Other Properties

Принадлежит: National Aeronautics and Space Administration NASA

Systems and methods for measuring phase dynamics and other properties (e.g. intracranial pressure) are disclosed. For example, the system may generate a reference waveform and a measurement waveform using digital synthesizers, each waveform having an identical constant frequency but also a relative phase shift. Next, system may send a tone-burst, via a transducer, into a sample (e.g. a skull or a bonded material), and then receive a reflected tone-burst in response. Then, a phase difference between the received tone-burst and the measurement waveform may be determined with a linear phase detector. Next, the phase shift of the measurement waveform may be adjusted, by the determined phase difference, such that there is no longer any phase difference between the received tone-burst and the adjusted measurement waveform generated by the appropriate digital synthesizer. A similar adjustment may occur after subsequent tone-bursts, allowing accurate monitoring of continuously variable phase relationships.

A method for an optical elastography system converts digital images of an actuated breast into a description of surface motion. The surface motion can subsequently be used to ascertain whether the breast has regions of abnormal stiffness, e.g., indicating a significant likelihood of breast cancer. The steps of the method use a model based segmentation to identify profile of the breast in each image, and for each pair of images computing skin surface motion using an optical flow algorithm. This method eliminates a preliminary step of placing fiducial markers on the subject.
