Evaluation of the applicability of the Flash Format for the production of radiological learning objects used in an e-learning environment.
Five exemplary learning objects with different didactic purposes referring to radiological diagnostics are presented. They have been intended for the use within the multimedia, internet-based e-learning environment LaMedica. Interactive learning objects were composed using the Flash 5.0 software (Macromedia, San Francisco, USA) on the basis of digital CT and MR images, digitized conventional radiographs and different graphical elements prepared as TIFF files or in a vector graphics format.
After a short phase of initial skill adaptation training, a radiologist author was soon able to create independently all learning objects. The import of different types of images and graphical elements was carried out without complications. Despite manifold design options, handling of the program is easy due to clear arrangement and structure, thus enabling the creation of simple as well as complex learning objects that provided a high degree of attractiveness and interaction. Data volume and bandwidth demand for online use was significantly reduced by the Flash Format compression without a substantial loss of visual quality.
The universally compatible Flash Format offers an opportunity for the simple production of radiological learning objects that fulfill all relevant needs of modern internet based e-learning environments, such as interactivity, employment of multimedia and convertibility.
评估Flash格式在制作用于电子学习环境的放射学学习对象方面的适用性。
展示了五个具有不同教学目的、涉及放射诊断的示例性学习对象。它们旨在用于基于互联网的多媒体电子学习环境LaMedica。交互式学习对象是使用Flash 5.0软件（美国旧金山的Macromedia公司），基于数字CT和MR图像、数字化的传统X线片以及以TIFF文件或矢量图形格式准备的不同图形元素组成的。
经过短暂的初始技能适应训练阶段后，一位放射科作者很快就能独立创建所有学习对象。不同类型图像和图形元素的导入过程没有出现问题。尽管有多种设计选项，但由于程序布局清晰、结构合理，操作起来很容易，从而能够创建出具有高度吸引力和交互性的简单及复杂学习对象。Flash格式压缩显著降低了在线使用的数据量和带宽需求，同时视觉质量没有大幅损失。
通用兼容的Flash格式为简单制作放射学学习对象提供了机会，这些对象满足现代基于互联网的电子学习环境的所有相关需求，如交互性、多媒体应用和可转换性。
