提出了一种计算钨阳极x射线管x射线光谱的软件程序SpekCalc。SpekCalc主要用于医学物理背景，用于研究和教育目的，但也可能对工业中使用x射线管的人员感兴趣。值得注意的是，可以建模的管电位（40-300 kVp）和阳极角度（建议：6-30度）的范围特别广：因此，该程序可能用于那些从事表面/正电压放疗以及诊断放射学的工作。该实用程序可免费下载，并基于x射线光谱生成的确定性模型（Poludniowski 2007 Med. Phys. 34 2175）。可过滤七种物料（空气、水、be、Al、Cu、Sn、W）。在本说明中描述了SpekCalc，并展示了说明性示例。预测与最先进的蒙特卡罗代码（BEAMnrc）进行比较，并在可能的情况下与另一种广泛使用的频谱计算程序（IPEM78）进行比较。
A software program, SpekCalc, is presented for the calculation of x-ray spectra from tungsten anode x-ray tubes. SpekCalc was designed primarily for use in a medical physics context, for both research and education purposes, but may also be of interest to those working with x-ray tubes in industry. Noteworthy is the particularly wide range of tube potentials (40-300 kVp) and anode angles (recommended: 6-30 degrees) that can be modelled: the program is therefore potentially of use to those working in superficial/orthovoltage radiotherapy, as well as diagnostic radiology. The utility is free to download and is based on a deterministic model of x-ray spectrum generation (Poludniowski 2007 Med. Phys. 34 2175). Filtration can be applied for seven materials (air, water, Be, Al, Cu, Sn and W). In this note SpekCalc is described and illustrative examples are shown. Predictions are compared to those of a state-of-the-art Monte Carlo code (BEAMnrc) and, where possible, to an alternative, widely-used, spectrum calculation program (IPEM78).
