在B超仪上用Polaroid相机拍摄图象,照片瞬时可得,迅速方便。但成本昂贵,拍摄多幅时势必加重患者的经济负担,而且没有底片,无法存档、随访、会诊、学习交流。为此,我们试验用普通照相纸代替昂贵的Polaroid胶片直接拍摄照片,能满足一般B超照片的要求。每幅照片成本仅几分钱,既利于患者,也方便了我们自己。现将此方法介绍如下,供感兴趣的同道参考。
In the B-meter with Polaroid camera to take pictures, instant photo available, quick and easy. However, the cost is high. It is bound to exacerbate the financial burden on patients when shooting multiple images. Moreover, there are no negatives and can not be archived, followed up, consultation, study and exchange. For this reason, we experimented with ordinary photographic paper instead of expensive Polaroid film direct photos, to meet the general B-photo requirements. Cost per photo is only a few cents, both for patients, but also to facilitate our own. This method is introduced below, for the same fellow reference.
