An opinion survey was conducted to judge the diagnostic potential of panoramic surveys with image detail similar to periapical radiographs exposed by free-focus radiography. Fifty dentists evaluated four free-focus radiographic surveys of the maxillofacial complex made on nonscreen film, which were selected to illustrate most categories of common dental disease. Conventional rotational panoramic radiographs were available for comparison. Fifty-four percent to 70% selected positive responses to questions on film size, image detail, anatomic area of coverage, and potential value in dental practice. Relatively high percentages of reviewers preferred smaller anatomic coverage and film size. About one third thought that the level of image detail ought to be even better. The overall interest in a nonpanoramic free-focus radiography exposure mode was guarded. Seventy-six percent of all respondents believed that the free-focus radiography films were "experimental."
开展了一项意见调查，以评估全景检查的诊断潜力，其图像细节与自由聚焦射线照相术所拍摄的根尖片相似。五十名牙医对在非增感屏胶片上进行的四张颌面复合体自由聚焦射线照相检查进行了评估，这些检查被选来展示大多数常见牙科疾病的类别。有传统的旋转全景片可供比较。在关于胶片尺寸、图像细节、解剖覆盖区域以及在牙科实践中的潜在价值的问题上，54%至70%的人给出了肯定回答。相对较高比例的评审者更喜欢较小的解剖覆盖范围和胶片尺寸。约三分之一的人认为图像细节水平应该更好。对非全景自由聚焦射线照相曝光模式的总体兴趣不高。所有受访者中有76%认为自由聚焦射线照相胶片是“试验性的”。
