用ANSI标准C编写了求解准直有限直径光子束垂直入射到多层组织上的响应的卷积程序(CONV)，因此该程序可在各种计算机上执行。该程序采用扩展的梯形积分规则，将响应卷积到由配套程序(MCML)计算的无限窄的光子束。对于COV和MCML都采用动态数据分配，因此，网格系统的组织层和网格单元的数量在运行时可以变化。由于没有单独对第一个光子-组织相互作用进行评分而导致的潜在错误如图所示，该程序包括源代码，自1992年以来一直在公共领域，可以从http://biomed.tamu.edu/similar到1w的网站下载。(C)1997年爱思唯尔爱尔兰科学有限公司。
A convolution program (CONV) solving responses to a collimated finite diameter photon beam perpendicularly incident on a multi-layered tissue has been coded in ANSI Standard C, hence, the program can be executed on various computers. The program, employing an extended trapezoidal rule for integration, convolves the responses to an infinitely narrow photon beam computed by a companion program (MCML). Dynamic data allocation is used for CONV as well as MCML, therefore, the number of tissue layers and grid elements of the grid system can be varied at run time. The potential error due to not scoring the first photon-tissue interactions separately is illustrated, The program, including the source code, has been in the public domain since 1992 and can be downloaded from the web site at http://biomed.tamu.edu/similar to 1w.
