DICOM medical image processing: web pacs 3. PHP extension skeleton, dicompacsBackground: In the last two column blogs, we have explained how to build a web pacs environment. If the backend of the platform is not related to DICOM, there is actually nothing to do with PACS, so the last few articles seem to have some run-off questions, but don't worry. The establish

PACS is short for the picture archiving communication system, PACS has extended from image storage and communication between several simple radiology and imaging devices to operations between all hospital imaging devices and even images of different hospitals. Therefore, many classification methods have emerged, for example, the networking of several radiology devices is called minipacs (micro

Stealth VR, (0028,0004) photometric interpretation equal to MONOCHROME1 or MONOCHROME2 it is really convenient to parse out pixel data, but dicom files are various , it's really hard to write a JS file that includes a transmission syntax and a variety of pixel structures. Also take into account the multiple-frame dynamic image, if a large number of needle images of the entire file download down to resolve the estimated browser will be completely burst. So I don't think this is a very practical

background:The last two columns are all about the building of the Web PACs environment, if the platform back-end does not carry out dicom related operations, in fact, there is no relationship with PACs, so the recent several seemingly somewhat off-topic, but we do not worry, The construction of the development environment itself is a huge and difficult project, such as debugging a good environment follow-up

background:At the weekend, I saw an article from my former colleague, speaking about the PACS system under the new Internet situation. Just the last column also mentioned the impulse to build a worklist server, so the search for the original student time to build the simple Web PACs found out, through the opportunity to build again to learn about Web PACs related

The network of information enables the staff to search, use, and maintain various information on the network, improving the daily office efficiency. At the same time, it also poses an increasingly serious challenge to information security. Due to business needs, on the one hand, people hope that the network can be fully connected and their terminals can access all the resources they care about. On the other hand, people require the network to be able to control access to networks of different so

Background: A long preview of several column posts has not been sorted out, mainly because the WML server plan that I wanted to build earlier was having problems. At first, the DCMTK official document Wwwapp.txt combined with the WAMP server that was set up two days ago can implement WML services smoothly, so you can complete the Web PACs series as well as build two blog posts of dicom WML server. However, in the actual deployment process found a few

background:As mentioned in the previous column, the local DCMTK and Cximage library responses are initiated by using CGI or fastcgi technology to forward user requests sent by the browser. The processing result is then converted to a regular image to be returned to the browser to implement the Web PACS. This blog post through the actual code test to verify the feasibility of this model, at the same time, the C language writing CGI script raised some q

The HTML5-based PACs, which was completed in the previous period, can be run on Google Chrmoe Browser, Mozilla Firefox browser, the Android system and iOS system phones and tablets are also perfect support. However, ie browser support for HTML5 is not ideal, only IE10 and the above version of the HTML5 support is more perfect. But many hospitals in the domestic PC or personal computer still stay in IE6, IE8, IE9 level, and IE browser is the highest ra

The displayed image must have diagnostic significance and quality (diagnostic quality ). A.

background:In the last blog post for the introduction, introduced a magical open source PACs system--orthanc. This article begins by interpreting the relevant content in the official cookbook, and for simple browsing, access and uploading please read the previous blog post. The modification and anonymity of DCM images has not been seen in conventional PACs systems, so this focus is on Orthanc's modification

Based on the HTML5 PACs system, the basic image browsing, image manipulation, image measurement, JS Local adjustment window width and other functions have been realized.

equals MONOCHROME1 or MONOCHROME2, JS parsing pixel data is really convenient, but dicom file a variety of , it is really laborious to write JS files that include the transmission syntax and the various pixel structures. Also take into account the multi-frame dynamic image, if the multi-pin image is large, the entire file is downloaded to parse the browser will completely collapse. So I think this way is not very feasible. (although this process is implemented in the display of the VR dicom fil

Last time blog post (based on HTML5 's PACS--HTML5 image processing (7) to realize the Client JS window width window), we introduce how to use the dicom pixel data parsed in the background to generate the image to be displayed and adjust the window width in the JS end.
