FAQ – Frequently asked questions

Quick overview of how system works

While viewing images on a PACS, the user selects image(s) to be saved to the RadPix Teaching File. The user then sends the images from the PACS to RadPix.

The DICOM images are received by RadPix.  Images are assembled into individual cases and placed in the draft area.

The user then views the Draft cases, and selects a case to be edited.

Information including history, findings, discussion, etc. are added to the case and saved.

Key images are annotated with built-in drawing tools.

Case is saved and completed.

Entire process can take as little as a few minutes!

What is the typical workflow with a PACS and RadPix?

When the radiologist finds images that he or she would like to put into a teaching file, he/she selects the images on the PACS, and then clicks the send button to send the images to the RadPix server. This workflow prevents the radiologist from being distracted making teaching file cases when he or she should be interpreting cases.

Typically, only selected images are sent, rather than entire cases. The images are processed by the server as they are received and a draft teaching file is created. The draft case is ready to be reviewed almost immediately.

The radiologist logs into the RadPix server and views the “Draft” cases to find a specific case. Selected images, and content are visible on the Draft page. The system can be configured to include the patient name and number visible if desired. In an active RadPix system, there can be many cases in draft status. Clickable buttons are present, allowing the user to filter on subspecialty and modality, making the cases easier to find. Additional buttons can be added as needed to filter the cases.

The draft case is then opened and text can be added into fields such as “History”, “Findings”, “Diagnosis”, etc. Meta-data such as author names, level of difficulty, access level can also be set. Images can be windowed / leveled as needed and the settings saved. Image annotations, including arrows, text, painted reions can be added to show the abnormalities on the images.

The user can download the case containing images and text into a PowerPoint file or complete the teaching file for future viewing.

What formats are supported for exporting images and text?

  • JPG
    • Original size high quality images
  • Publication quality TIFF including annotations
    • 300 DPI x 5 inches
    • Correct size for publication
  • PowerPoint
    • Single slide with all images on it, has scroll bar to advance through the images.
    • Single image on each slide with separate slides for text fields including History, Findings, Diagnosis, etc.
  • DICOM
    • Anonymized DICOM files
      • Embedded patient information in the image data can be removed by the system

What is the process used for publishing a teaching file case?

Depending on the system, publishing case can be as simple as just completing a case in the editor.  RadPix also supports a traditional reviewing process, with editors, reviewers, etc. as outlined below.

Four different user roles can be set up to support a publishing workflow, starting with author, then reviewer, then editor and finally publisher.

  1. Users with the author role can create cases and then submit them to the reviewers.
  2. The reviewers can accept the case and send the case to the editor or send it back to the author with comments.
  3. Editors review the cases next, and have the option to send it to the publisher or can send the case back to either the author or reviewers, again, with comments.
  4. Publishers next review the cases and can complete them and publish them on the same or another RadPix server, or send the case back down for further editing.

A defined checklist of tasks for each level is recommended, including checking for patient information in both the text and images.

 

How do I upload DICOM files on my computer or from a CD to RadPix?

If the DICOM files are already on your computer, or they are on a portable device such as a CD or USB drive, you will need a program to upload the files.  The Radiological Society of North America has created such a program called FileSender.  Click here for FAQ with more information and instructions for use.
