Abstract: By the concentric raster method which performs the real-time coordinate transformation in the supersonic sector scan the composite scan is available. After the data acquisition is achieved the coordinate transformation of rectangular coordinate is performed by only first order interpolation from the acquired data. Also this method cna be applied to achieve simply the composite scan conversion where several supersonic elements are arranged in the shape of an arc.
Abstract translation: 通过在超音速扇区扫描中执行实时坐标变换的同心光栅方法，复合扫描是可用的。 在实现数据采集之后，通过从获取的数据进行一阶插值来执行直角坐标的坐标变换。 此外，该方法也可以应用于简单地实现复合扫描转换，其中几个超音速元件被布置成弧形。

Abstract: This invention relates to a focusing method of ultrasound imaging signal in ultrasound imaging system. This new focusing method can perform the continuous dynamic focusing by eliminating the analog delay device and also has excellent resolution and simple structure. In the method for focusing the ultrasound imaging signal, the ultrasound signal which is reflected from the object is converted into electrical signal in the array transducer formed of N transducing devices. The differences of delayed time among the ultrasound signals are compensated by the sampling-delay method. The time dealys occur due to the difference among the array position of transducing devices.
Abstract translation: 本发明涉及超声成像系统中的超声成像信号的聚焦方法。 这种新的聚焦方法可以通过消除模拟延迟器件进行连续动态聚焦，并且具有优异的分辨率和简单的结构。 在用于聚焦超声成像信号的方法中，将从物体反射的超声信号转换成由N个换能装置形成的阵列换能器中的电信号。 超声信号之间延迟时间的差异由采样延迟法补偿。 由于换能装置的阵列位置之间的差异，发生时间变化。
