但是因为计算机构建内部图像时采集的是多角度拍摄数据,而不是靠摄影胶片上的单一曝光影像,所以电脑断层扫描术能够捕捉细节并记录下传统放射学无法看到的软组织。

底片

卤化银转变为黑色的银,就会有黑白负片的效果
上图的原始版本
碟式底片匣

底片,是一种成影像机器。现今广泛应用的底片是将卤化银涂抹在聚乙酸酯片基上,此种底片为软性,卷成整卷方便使用,所以又称胶卷,当有光线照射到卤化银上时,卤化银转变为黑色的银,经显影工艺后固定于片基,成为我们常见到黑白负片。彩色负片则涂抹了三层卤化银以表现三原色。除了负片之外还有正片及一次成像底片等等。

早期的底片用玻璃作片基,19世纪晚期塑胶工业技术成熟,压成薄片的塑胶片取代玻璃成为片基。

底片以感光速度(din/ISO)来分别,由最低速之ISO25度至高速之ISO3200,一般来说感光度越低,画质越细腻。最常用的胶卷为din21度/ISO100,其次是快片,即din24度/ISO200。其它速度的胶卷,由于价格,冲片技术要求特殊,在2000年左右数字摄影兴起后,几乎只有专业人士才会使用。

Plot of image density (D) vs. log exposure (H), yields a characteristic S-curve (H&D curve) for each type of film to determine its sensitivity. Changing the emulsion properties or the processing parameters will move the curve to the left or right. Changing the exposure will move along the curve, helping to determine what exposure is needed for a given film. Note the non-linear response at the far left (
This article is mainly concerned with still photography film. For motion picture film, please see film stock.

Photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film.
