A diaphragmatic compensating filter for hepatic angiography. 一种用于肝血管造影术的膈补偿滤光片。

To enhance the clarity of angiographic images, a diaphragmatic compensating filter (DCF) covering the sub-phrenic portion was constructed. The required shape of a DCF for a high optical density part of the angiograms was determined by the distribution limit of the outline of the diaphragms, but the shape of the low optical density part could not be specified. The smallest tolerance of a DCF for the respiratory motion of a diaphragm was 13.2 mm at the film. Thus, a DCF was effective in more than 95.8% of angiograms. Our clinical results showed remarkable improvement in those images. The clinical areas between radiographic images with and without a DCF were improved by more than 27% according to an image analysis system. Therefore a DCF is indispensable in conventional hepatic angiography and digital subtraction angiography. In addition, only one type of a DCF is possible for use in combination with lateral compensating filters.

为了提高血管造影图像的清晰度，构建了覆盖膈下部分的膈补偿滤光片(DCF)。血管造影中高光密度部分所需的DCF形状由横膈膜轮廓的分布极限决定，而低光密度部分的形状无法指定。DCF对膈膜呼吸运动的最小容差为13.2 mm。因此，DCF在超过95.8%的血管造影中有效。我们的临床结果显示这些图像有了显著的改善。根据图像分析系统，有和没有DCF的放射图像之间的临床面积提高了27%以上。因此，在传统的肝血管造影和数字减影血管造影中，DCF是必不可少的。此外，只有一种类型的DCF可以与横向补偿滤波器组合使用。

Teaching psychology to student radiographers: a survey of current methods and attitudes. 对学生放射技师的心理学教学:当前方法和态度的调查。
Radiography today

N Hughes

A number of schools of diagnostic radiography were surveyed by questionnaire to establish current trends and status of psychology teaching. The results show that methods used are split fairly equally between experiential and nonexperiential techniques. Reasons for the utilisation of role play methods are explored, and several comments are reproduced concerning the future of psychology teaching and aspirations for the future.

采用问卷调查的方法，对多所放射诊断学校的心理教学现状进行了调查。结果表明，所使用的方法在经验和非经验技术之间是相当平等的。探讨了使用角色扮演方法的原因，并就心理学教学的未来和对未来的期望发表了一些评论。
