Java Viewer User Manual

This document is the user manual for the SIMBA java viewer tool.

The main topics of this manual are:

Below is a quick reference describing all the steps necessary to review a image data set.

Quick Reference - Procedure for Reviewing a Scan

  1. View a case by entering the case number and pressing Request Case
  2. Click the yellow View button to open an image data set.
  3. Scroll throughout the image data set until the region of interest (ROI) is visible.
  4. Optional steps:
    • add annotations to any point or area of the image data set, or
    • take a measurement of a Region of Interest, and save it as an annotation
  5. Repeat the previous steps for all images of the image data set.

Image Viewer Modes

The Java Image Viewer supports different modes of viewing images that are described in the following sections. There are three modes available: single panel, compact and double panel. They can be selected by choosing the wanted entry in the drop-down list at the top of the page.

The fourth entry, compatibility mode, selects a viewer with very limited capabilities that does not require a java plugin to be installed on the client web browser. This should only be used when a java capability is not available on your computer. It has very limited functionality and may not display some image types.

Note, when the viewing mode is changed the viewer page is reloaded with the first image that it originally displayed (not the image that you may be currently viewing when making the change).

Single Panel Mode
When operating in this mode, the image viewer consists of two sections. The image appears on the left and the control panel appears vertically on the right. The control panel consists of the image navigation panel, the windowing panel, the measures and grid panel and the boundary editing panel. When the image viewer starts it will automatically show the initial slice of the first annotation, if any, associated with the image data set.

When working in single panel mode, the viewer will show the annotation/case-browser panel as a separate window that opens at the right hand of the image window.

Compact Single/Annotations Mode
When working in compact mode, the annotation/case-browser panel is embedded in the same window as the image panel. In this case the control panel develops horizontally below the image panel with the same blocks as is the single panel mode: the image navigation panel, the windowing panel, the measures and grid panel and the boundary editing panel.

Double Panel Mode
The double panel mode lets the user visualize two diffent views of the same image data set or the concurrent visualization of two different image data sets (or images). The control panel is horizontal and the annotation and file browser panels appear as (mutually exclusive) pop-up windows on the opposite side of the relevant image panel.

Other Modes
There are two additional modes, but they require large screens:

  • Quad Panel, and
  • Large Single
In quad panel mode, four viewers are displayed; similarly to the dual panel mode, the quad panel mode allows the user choose up to four different data-set to be visualize. Control panels for each viewing panel are placed vertically by their sides and file browser panels appear as (mutually exclusive) pop-up windows.

The large single mode is a single mode with a viewing area of 1024 by 1024 pixels versus the 512 by 512 pixels of the regular single mode. Last updated 2020-07-15, APR
