OSCaR
OSCaR是一个锥形束CT(容积CT)重建算法,为AAPM开发的一个开源matlab gui代码,其投影数据需要到官方网站下载。也可以使用varian或者医科达的cone beam ct 投影进行重建。( OSCaR is a code about the reconstruction of cone beam CT, it is GUI,and very friendly。)

直线阵自然指向性仿真,先根据设定的角频率仿真单频信号A sin(ωt);再根据阵元间距、入射角度计算得各阵元相对参考阵元接收的信号的时延 τ (dsin(θ))/c。
假设等间隔N基元线阵,入射信号是平面波,那么阵元输出信号为:S_n (t) A sin(ωt+nφ);其中 φ 2πfτ 为相邻阵元接收信号间的相位差;再将基阵各元输出求和,取最大值max,就得到输出幅度;以入射角为横坐标,幅度为纵坐标作图得直线阵自然指向性。
