Build Medical Radiology DICOM Viewer in HTML 5 & jQuery for iPhone


For Medical Radiology domain, it’s indispensable to develop DICOM Viewer in order to view medical images (CT, MR, Endoscopy,X-Ray) on smartphones. For desktop it’s easy to build for webkit browsers (Mozilla Firefox, Chrome) on HTML 5 & jQuery. Lets develop such app for iPhone.

To build this app, several js libraries are needed which is available @ github.

  • Lets check for the code to build the DICOM Web viewer on HTML 5 :

<html>

<head>

}

}

// main application

var  app = new dwv.App();

// jquery

$(document).ready(function(){

// create buttons and dialogs

$(“button”).button();

$(“#openFile”).dialog({ position: [10, 110] });

  1. Please point the all JS files URLs or else please upload your work to Github.. Great work

  2. René Laqua says:

    Impressive Work! I would love to see the whole source code, if this is possible. Are you planing to release your work as open source or freeware?

  3. nycvacationrental says:

    good work, i’m also intereste din which JS file from github you used. thanks.

  4. nycvacationrental says:

    it’s right in the code. https://github.com/ivmartel/dwv this is the js used.

  5. ivmartel says:

    Hi, I’m the developer of the dwv. Any comments, bugs, suggestions are welcome! The full code and a demo are available on github.

  6. redoxitive says:

    hi,
    I want to open a dicom file via http server. you know now only local files.
    I think I must simulate javascript readAsBinaryString function in server with c# .net.
    but I got encoding problems.

    do you have an idea about this?

  7. Nice work Anindita, i need to run the same code in Android but this code not run in Android mobile can please provide code for android Jquery App.

  8. pabloyepes says:

    Excellent job. Would you have an updated version? I would like to see a CT scan with multiple slices. I see you foresaw that in the code but it is not implemented yet.
    I would also like to add the organ contours and dose delivered for radiotherapy

  9. pabloyepes says:

    Ok, I got it, but it is v0.4beta. Can you read the contours from a DICOM file?
    What needs to be done to include multislice? I’ll be willing to help.
    When do you think you will have the multi-slice option available?

    • ivmartel says:

      v0.3 is the latest stable version, v0.4 is in progress. They cannot read contours from DICOM but I would be interested, would you have data you could share that contains contours? About multislice, I would like to have something ready in a month or so. Thanks for proposing to help, feel free to fork the repository and add your improvements. I’ll merge them back once ready.

  10. pabloyepes says:

    Ivmartel,
    Ok, thanks. I am not familiar with this code development environment (forks), but let me see what I can do.
    How can I send you a patient with contours?

  11. pabloyepes says:

    I just sent you a set of CT, with a contour file (structures) and a few dose files.

  12. soheilrad says:

    First of all i should thank you for your rich and advance DICOM library ,
    I can see that you are always answering to all the questions perfectly,
    I have problem while using your DICOM library ,let me ask :
    How I can user thumbnail image and define Click event for all thumbnail images and then i want to show real image in canvas on each thumbnail Clicking, how can i do it ?
    Thanks in advance.

    • ivmartel says:

      If you are talking of thumbnails from a database of images, like a PACS, then this should be done by the web of the PACS. If WADO is enabled, you can query the images in jpg/png format, from all the Uids you could generate a thumbnail page. It would be too costly to generate the thumbnails from the generated canvases of dwv. Hope this answers your question…

  13. soheilrad says:

    Thanks ivmartel

  14. miquinti says:

    First, I do agree with other comments about your great work,
    I have tried to import the proyect with eclipse and I get problems because Eclipse change the main structure. How can I do to make the proyect works within Eclipse or should I use other IDE?

    Thank you very much in advantage.

  15. can u please explain the flow of converting the dicom image to jpeg2000

  16. thanks for your help . how can we generate the thumbnails for the above process…for dwv viewer

  17. vivek gupta says:

    Hi All,

    I want to pick Dicom image from server URL. Please guide me or provide any live example source code. I am using code from https://github.com/ivmartel/dwv. Here i saw we can passed URL but unable to replicate it.

    Thanks,
    Vivek
