Abstract(in English) | Ultrasonic diffraction method is the mthod of structure estimation which is aimed to diagnosis structural change of the part of disease disturbance and to clarify role of living tissue. We observe the diffracted waves by tissue at a focus position of the transducer in this method. Then, by observing at the position which slipped from a focus, estimated precision varies. It is important to find an accurate focus in order to estimate structure in high precision. As the method for estimating it, we suggest to use MUSIC which is a microphone array signal processing. |
