Worklist is your gateway to the online image database. To start
working with the worklist, click on the "WList" button
on the web PACS interface. This will open the worklist window. Set
your compression (use "Exact colors" for no compression)
and memory preferences at the right bottom of the worklist window,
or use the defaults (maximum compression, lowest memory usage).
If your computer memory is not sufficient for a particular image
series to load, Web PACS will attempt to load the best suitable
subset of this series and reduce image sizes. For instance, if the
series contains 100 images, and only 50 can fit in your computer
memory, Web PACS will load every second image. To search for a particular
patient, click the "Start search" button, and enter a
mask for patient name and/or patient ID. If you leave all search
fields blank, all current records in your worklist will be retrieved
(default). Patient name mask like A* stands for all patients with
names starting from A, etc. Each patient record contains one or
several studies, each study - one or more series, and each series
- one or more images. That is why the worklist has patient (default),
study, series and image views (levels). Going down from level to
level in the worklist is performed by double-clicking on particular
item in the list. For instance, double-clicking on the patient line
in the patient view will show the list of all studies for this patient.
To return back to the higher level, click on the first worklist
line. Double-clicking on the image name at the image level opens
that particular image. Web PACS interface displays one image series
at a time. So, at the patient or study levels, clicking on the "View
series" button opens all images in the first (most recent)
series for the selected patient/study. "Next" and "Prev"
buttons take you to the next or previous image series for the current
patient/study, if any.
You add new patient records by uploading new DICOM image files.
To upload new DICOM file(s), click the "Upload Patient Data"
button in the database window. This option is available to registered
users only. Currently, we do not impose any quota limits per user,
but please try not to exceed 50 MB for your data. All the images
you upload under your personal account are private and visible only
to you. You can make them public by clicking the access button on
the Worklist. This button works in the study view, and changes the
access flag for the entire study. If you make a study public, it
will become visible for all default, "guest" users - use
this to get a second opinion on your case. By clicking the same
button for the public study, you'll make the study private again.
Web PACS interface displays a toolbar with the most common PACS
functions (tools). Click on a tool button to activate the corresponding
tool. The following tools are available:
1. WList - displays the worklist
2. Zoom - zooms current image(s) in and out
3. Pan - scrolls the images (if they are larger than their frames)
4. W/L - window/level (brightness and contrast)
5. Size - measure the distance in the current image. If DICOM file
for this image contains no physical size scale, the sizes can be
measured only in pixels
6. ROI - select and analyze rectangular Region Of Interest
7. Notes - view or update study note for the current study
8. Reset - restores default image view
9. Cine - scrolls through the sequence of images
10. All (or double-click on the image) - switches between single-image
(image stack) and multi-image views. If you have too many images
in the current view, stack them with Cine or All to see more image
details
11. Prev/Next - download and view previous/next series in the current
study
To work with Zoom, Pan, W/L Size, ROI and Cine, check the button
first, and then drag a mouse with the left button pressed over the
image area to apply the selected tool.
