目前，人们对回声针和适中针插入角度下的波束控制的作用了解甚少。麻醉师对以 40 度、50 度和 60 度插入猪肉的回声和无回声针的超声图像进行评分，评分范围为 0-10。还探讨了不同级别的波束控制的效果。在 40 度时，陡峭的波束转向将无回声和回声针的可视化提高到相同、令人满意的水平。在 50 度和 60 度时，非回声针的可视性较差，而回声针的可视性足够，并且可以通过陡波束转向来改善。
Currently, there is little understanding of the role of echogenic needles and beam steering at moderate angles of needle insertion. The ultrasound images of the echogenic and nonechogenic needles inserted into pork at 40 degrees, 50 degrees, and 60 degrees were scored by anesthesiologists on a scale of 0-10. The effect of different levels of beam steer was also explored. At 40 degrees, steep beam steering improves visualization of both nonechogenic and echogenic needles to an equal, satisfactory level. At 50 degrees and 60 degrees, visualization of nonechogenic needles is poor, whereas visibility of an echogenic needle was adequate and may be improved with steep beam steering.
