The validity of the Rigiscan as a measure of both penile circumference and rigidity was assessed. In the first study, the Rigiscan was used simultaneously with a mercury-in-rubber strain gauge to monitor nocturnal penile tumescence. The Rigiscan was found to underestimate the circumference proportional to the degree of erection. In a second study a calibration system was developed which allowed independent variation of circumference and rigidity. Assessment of the Rigiscan with this system confirmed that circumference was underestimated, particularly at lower levels of rigidity, and also that different devices consistently recorded different degrees of rigidity. The use of this type of system for regular calibration is recommended, and other potential improvements in the device for research purposes are discussed.
评估了Rigiscan作为阴茎周长和硬度测量工具的有效性。在第一项研究中，Rigiscan与橡胶汞应变仪同时使用，以监测夜间阴茎勃起。结果发现，Rigiscan低估了与勃起程度成正比的周长。在第二项研究中，开发了一种校准系统，该系统允许周长和硬度独立变化。使用该系统对Rigiscan进行评估证实，周长被低估了，尤其是在较低硬度水平时，而且不同的设备一致记录了不同程度的硬度。建议使用这种类型的系统进行定期校准，并讨论了该设备在研究目的方面的其他潜在改进。
