| 摘 要： | 超声换能头进行数据采集时,有时要求换能头和被成像体垂直或者倾斜一个固定的角度采集数据,探测被成像物体的能力非常依赖于换能头和探测对象之间的相对运动,但由于人为因素该角度很难固定,所以采用数学方法讨论其变化对测量结果的影响.

| Abstract: | Sometimes the ultrasonic transducer should be perpendicular to the imaging project or there is an angle between them When the datas from body are acquired by ultrasonic transducer.The capability of obtaining useful information about imaging project depends on the reference movement between the transducer and the imaging project heavily. The angle is difficult to be determined as artifical factors exist. So explore how the changement of the angle influence the result by the means of maths. |
