Because high spatial resolution and contrast resolution were necessary for mammography, the digitization of mammography was the latest in a medical image. However, digital mammography begins to be put to practical use by recent technical development. We compared observer performance in the detection of breast cancer on hard copy film, 3-Mega liquid crystal display (LCD) monitor and 5-Mega LCD monitor. As a result, soft-copy reading with 3M- and 5M-LCD was comparable to the reading on hard copy film in the ability of detecting breast cancer. In addition, there was no significant difference between 3M- and 5M-LCD in detection of breast cancer.Furthermore, we investigated influence on changing hard copy reading to soft copy reading. As a result, there were no significant differences between hard copy reading and soft copy reading in total, however, there were some differences according to findings. As for the mass, no differences were observed between hard copy reading and soft copy reading. As for the calcification, recall rate was decreased in soft copy reading. On the other hand, as for the other findings, the recall rate was increased in soft copy reading.In order to use the full ability of digital mammography, further investigation should be performed not only on peripheral equipments but also on its reading methods.

由于乳腺X线摄影需要高空间分辨率和对比度分辨率，因此乳腺X线摄影的数字化是医学图像中最新的技术。然而，随着最近的技术发展，数字乳房X线摄影开始投入实际应用。我们比较了观察者在硬拷贝胶片、3兆液晶显示器 (LCD) 显示器和 5兆液晶显示器上检测乳腺癌的表现。因此，在检测乳腺癌的能力方面，使用 3M 和 5M-LCD 进行的软拷贝读取与硬拷贝胶片上的读取相当。此外，3M-LCD和5M-LCD在乳腺癌检测方面没有显着差异。此外，我们还研究了将硬拷贝阅读改为软拷贝阅读的影响。结果，硬拷贝阅读和软拷贝阅读总体上没有显着差异，但根据调查结果，存在一些差异。至于质量，硬拷贝读取和软拷贝读取之间没有观察到差异。对于钙化，软拷贝阅读中召回率下降。另一方面，就其他发现而言，软拷贝读取的召回率有所提高。为了充分发挥数字乳腺X线摄影的能力，不仅需要对其外围设备进行进一步的研究，而且还需要对其读取方法进行进一步的研究。
