Studycast Viewer

Studycast Viewer

When you open the Study Viewer, the first image in the study is displayed. If the first image is a cine loop, it begins playing automatically. Thumbnails of available images appear in a scrolling list on the left side of the viewer. To view an image or loop, select it from this list. You can also navigate study images using the arrow keys on your keyboard and the play controls below the image.

Thumbnails of cine loops and image stacks have icons in their top right corner to differentiate them from single or static images.

Study Information

The patient's name, DOB, and study date appear at the top of the window. To see additional information, click the three dots to the right of the study date.
       If the study has attachments, the Attachments button will be active and will display the number of attachments. To open the attachments, click the button.
     If the patient has previous studies, the Other Studies button will be active. Click the button to see a list of previous studies available. Click on a study in the list to open it in a new tab.

DICOM Overlays

The viewer will display the following DICOM tags if they are present:
  1. Heart Rate (HR)
  2. Patient Name
  3. Patient DOB
  4. Sex
  5. Institution Name
  6. Study Date

View Multiple Images

When the Study Viewer opens, it displays a single image from the study. To view up to nine images simultaneously, use the control at the bottom left.
When viewing images in the viewing pane, you can choose any combination of images you'd like to see. Simply find an image in the list of thumbnails on the left. Then drag and drop the image into the viewing pane. When you open a new study, the viewer will default to the view you most recently used for the same study type.
To select the number and layout of simultaneous images in the viewer, move your cursor over the control. When the desired layout is highlighted in the control, click to select it.

View Reference Lines

For series that include reference line data, the reference lines will be displayed automatically in the inactive viewports when viewing multiple series simultaneously. Click a viewport to make it the active one. The reference lines in the inactive viewports automatically update as you scroll through the series in the active viewport.

To hide the reference lines, click the toggle at the bottom of the viewer. To once again show the reference lines, click the toggle again.

Speed and Sync

To control the speed of a cine loop, use the Speed slider control at the bottom of the Study Viewer.

When viewing two or four cine loops at a time, you can sync the loops using the SYNC menu at the bottom of the Study Viewer.

Sync Option - Description

  1. None - Cine loops play at their own rate and are not synced with each other.
  2. Start - All cine loops start at the same time and play at normal speed.
  3. Rate - All cine loops start at the same time and automatically adjust to end at the same time. Faster loops are slowed down to match the speed of slower loops.

Play All and Delay

To view all images in the list of thumbnails in sequence, click the Play All button in the bottom right. Use the Delay slider to set the amount of time the viewer displays each image. The delay value you select will be used for all studies and images until you choose a different value or close the browser.

View Controls

When you open a new study, the viewer will automatically select the control you used most recently for the same study type.

Function


WW/WC

For ultrasound and other imaging modalities that do not produce images with a high bit-depth, this control functions as brightness and contrast. To change the brightness, click and drag the mouse up and down in the viewport. To change the contrast, click and drag the mouse right and left. To apply brightness and contrast to all viewports (all images in the study), hold Ctrl key while dragging the mouse.

For CT scans and other modalities that produce high bit-depth images, the window width and window center control the range of grayscale that can be displayed. With this tool, the user can specify the range of colors that are visible. Colors above this range appear as white. Colors below this range appear as black.

To adjust these settings, click and drag the mouse in the viewport.  

•Right increases the window width

•Left decreases the window width

•Up increases the window center

•Down decreases the window center

 

For information on applying WW/WC presets, see WW/WC Presets for CT.
