An inaccurate identification and localization of needles lead to severe inadvertent complications and increased procedure times. This is due to the inherent specular reflections from the needle with directivity depending on the angle of incidence of the US beam, and the needle inclination. Though several methods have been proposed for improved needle visualization, a detailed study emphasizing the physics of specular reflections resulting from the interaction of transmitted US beam with the needle remains to be explored. In this work, we discuss the properties of specular reflections from planar and spherical wave US transmissions respectively through multi-angle plane wave (PW) and synthetic transmit aperture (STA) techniques for in-plane needle insertion angles between 15°-50°.

摘要：在超声（Ultrasound, US）引导的介入手术中，对穿刺针的精准可视化与追踪是一项关键挑战，尤其是在平面内穿刺过程中。若对穿刺针的识别与定位不准确，将引发严重的意外并发症，并延长手术时长。该问题源于穿刺针固有的镜面反射特性，其指向性取决于超声束的入射角与穿刺针的倾斜角度。尽管已有诸多方法被提出以优化穿刺针的可视化效果，但针对超声透射束与穿刺针相互作用所产生的镜面反射物理机制的系统性研究仍有待探索。本研究针对15°至50°范围内的平面内穿刺针插入角度，分别通过多角度平面波（Multi-angle Plane Wave, PW）与合成发射孔径（Synthetic Transmit Aperture, STA）技术，探讨了平面波与球面波超声透射场景下的镜面反射特性。
