1 First, the cloud is not a film like this, this is not just for dressing bottle. Such figures are only in the full sequence of Radiology Department teacher image, the selected portion of the image, the patient does not get all their transactions; Further, an image (standard film printing) printed by N-Print is through the window width and window level after 8bit images, artwork has 12bit, 14bit, loss of too much information. Every time I see that manufacturers use this product to preach, to do the project, I would grievance for other cloud vendors film, this is the jpeg show, not only without the slightest technical difficulty, computing and storage resource requirements are very low, most hateful and also a decent standard of cloud vendors. So, we called for, must be identified on this form, "says the film" is not one cloud on the film track. Barbara cloud the film should be the Department of Radiology, Hospital Professional client and moved on ordinary browser.
2 professional browser, naturally these professional teachers are aware of. Geometric operation function, zooming, movement, rotation, lateral tilt up and down; functional window width and position, region of interest (ROI) tools, rapid, automatic, manual adjustment window width (WW / WL) adjustment, black and white reversed image sharpening and enhancements; labeling and measurement functions, for example, display scale, distance, angle, cross-section, the ROI (region of interest), the Cobb angle, measured CT value HU / region HU values, cardiothoracic ratio deviation angle tools; playback function; roaming function, with layer synchronization browse, locate draw the line, patient position display HFAPLR, patient information display;
Also MPR function of CT, MR image sequences in order to observe the crown, sagittal and axial images, wherein the positioning cut line may rotate, move, an adjustable layer thickness reconstruction; preferably includes beveled angle at any position generate a new functional sequences, are very important in the diagnosis of late archiving and printing; likewise, must have a measuring function; geometric operations functions; window width and position function; patient orientation display and information display; to facilitate teacher image for diagnosis.
The best, but also with VR volume reconstruction function, for quick RGBALut modify the common position, can customize change RGBALut curve, you can also adjust the window width and position display. Most cattle or professional level for a particular disease and treatment site, went to the extent of God's level, so far, I have not seen a deal can be done after professional 3D workstation level H5 browser.
最容易忽略的，但是在我看来比较重要的功能是具备多检查同屏展示的功能。通常在一个项目中，云胶片项目前期功能的确定，厂商的确定，方案的确定，大概和天天使用它的影像科老师没啥交集，汗~~~。但是，能展示多检查，并且以正确的挂片把对应的影像展示出来，对影像科老师真的太重要了。因为，看到历史报告和影像，对当前的检查是极具有参考意义的。同时，这个挂片功能还可以随意定义每个检查的展示屏幕和位置，也可以随意定义在每个检查的展示位置中，序列的分格；同样，也可以定义每个分格，需要选取的特定序列，此序列采用何种的特定缺省处理（靠左，居中，增强）等等复杂的设定。
3 多模态影像支持
特殊的模态有乳腺（MG），牙科（CBCT），PET/CT的融合功能影像浏览。这里，主要先说下乳腺，专业的乳腺工作站都是按照挂片协议工作流来设置工作流的。这是HOGICAL工作站的上协议来说明专业的乳腺工作站的挂片定义概念。另外，还要支持pdf格式的显示，html（SR模态），ECG等模态的展示
4. 速度和流量
速度其实很难去评估，主要还是网速的快慢，具体加载速度的优化，可以参考我的另外一篇文章https://blog.csdn.net/rendaweibuaa/article/details/95007461
这里可以稍微提一下加载图像的方式，大家很可能会忽略。实际项目中，我们发现，基层老百姓，流量还是挺宝贵的。所以，最好能做Lazy加载方式，也就是看哪张图，加载哪张图像。另外一种加载方式，是给院内wifi类用户使用，缺省将所有的影像全部加载，这种方式体验会很好，不比原生的程序的体感差。
5. 云胶片入口
5.1 二维码
5.1.1 可以院内PACS烧动态二维码，是云端二维的地址（一般不行）
5.1.2 PACS将PDF格式上传到云胶片厂商的前置服务器上，云厂商对此报告进行二维码烧写
5.1.3 院内PACS也可以只开放一个视图的方式，云胶片厂商将报告和检查信息收集到云端，通过配置模板，将从PACS获取的报告内容生成带有二维码的PDF（可能和医院模板稍有差别，但是不会影响实际使用）。
5.1.4 如院内PACS厂商不配合或者要的钱很多的情况下，也可以通过虚拟打印服务器自动截取打印pdf，然后识别、烧写二维码、然后再打印
5.2 公众号
由云胶片公司开发，通过设置菜单“查看云胶片”，进入历史列表；也可设置收费后再查看云胶片，收费方和关注公众号可以设置不同公众号。也可以通过匿名、期限、生成对应二维码方式
6 云胶片硬件配套
6.1 云胶片实体打印机
可以通过院内打印的条形码，扫描后直接打印出带有二维码的报告。然后通过扫描二维码的报告，绑定获取云胶片
6.2 临床、手术室阅片器
此设备是用来替换原有观片灯的设备，具有可移动，可触控，屏幕通过CFDA或者FDA的一款专业级产品。
7. 其他
围绕报告，现在又衍生出报告解读，二次问诊，名字解释，相似病例，AI病灶分类定位等等其他的业务，不详述。
