| Abstract(in English) | [Background] Transverse cross-sectional imaging of the intima-media complex of the carotid arterial wall is difficult to obtain using conventional linear scanning. The angular width of imaged regions of the anterior and posterior walls is limited. [Principle] In this study, multi-element spherical beam from a linear array transducer was investigated both by simulations and basic silicone-rubber tube experiment. Images of a simulated reflector-tube from simulated scanning and a silicone-rubber tube phantom were reconstructed by multi-angle receive steering and focusing from multiple sequential transmissions stepped across the entire cross-section. [Results and Conclusion] B-mode images obtained by the proposed method showed improvement in lateral resolution as well as increase in angular width of imaged region of the tube's wall. This angular width increases with increase in number of transmissions. |
