Basic Windows Operations

The Echelon MR System is based on Microsoft Windows and uses manystandard Windows functions and commands. If you are familiar with Windows,you will find that the Echelon MR System windows and menus operate in a waysimilar to those of other Windows-based applications. If you are not familiar withWindows, make sure that you review the information below about generalWindows operations.

Mouse Operations

To move around the Echelon MR System windows, you will use a mouse. Themouse operates the pointer that appears on your computer screen, as shown inthe example.

Pointer—Marker that moves on the screenwhen the mouse is moved. Normally, it is anarrow. However, its shape may changedepending on the operation. Mouse

3System Overview

QS4-36980v1 3 - 21

Mouse Buttons and Scroll Wheel Functions

You will use the right and left mouse buttons and the scroll wheel (the rubberdisk, or wheel, found between the left and right mouse buttons) to performvarious functions as described below.

To Click on an Object on Your ScreenMove the mouse pointer to the target object (such as a button or folder displayedin the window). Press and release the left button once so that a clicking soundcan be heard. This left-click operation is used to select buttons, menus, and otheritems.

Clicking with the right mouse button is referred to as a right-click. Right-clickingon a target object (a series, an image, or similar item) may display a shortcutmenu of tasks or options. This shortcut menu will vary, depending on the targetobject, and is useful for completing tasks quickly.

To Double Left-Click on an Object on Your ScreenMove the mouse pointer to the target object, then quickly press and release theleft button twice so that a click-click sound is heard. Double left-clicking can beused to open folders and perform other operations.

To Drag an Object on Your ScreenMove the mouse pointer to the target object, left-click and hold the left button,move the object to a new location, and then release the left button. This is usedfor operations such as moving items to different positions or loading output seriesto be used as input images.

To Move Up and Down in the WindowsAs the name of the scroll wheel implies, it is used for moving up and down(scrolling) in the various computer windows. Using a scroll wheel is particularlyhelpful when viewing images in the viewports. To scroll down, roll the scrollwheel backward (towards you). To scroll up, roll the scroll wheel forward (awayfrom you).

Changing Mouse Functionality

If you need to change the functionality of your mouse (such as the buttonconfiguration or click speed), you can do this in the Mouse Properties window.This window is described in the “System Settings Windows” section ofChapter 9, “Additional Launcher Functions.”

Note:The directions in this manualhave been written for a standardright-handed mouse button.If your mouse settings havebeen adjusted for a left-handeduser (that is, the right buttonfunctions as the left button andvice versa), then you will needto reverse the use of the rightand left mouse buttonsdescribed in this manual.



Window Features

The Echelon MR System provides you with numerous windows in which youcan perform operations. These windows have some standard features, which aredescribed below.

Title Bar

The name of the window will appear at the top in the title bar. The right cornerof the title bar may display some or all of these buttons:

Minimize—Shrinks the window from view, but still allows access from thetask bar.

Maximize—Enlarges the window to full screen.

Restore Down—Restores a maximized window to its previous size (not shownon the example).

Close—Closes the window completely.

3System Overview

QS4-36980v1 3 - 23

Menus and Toolbars

Many windows will have a menu under the title bar. This menu is a list of variousoperations that can be performed on that window. When you select a menu item,the commands that you can perform will be listed below that item. Once a menuitem is selected, you can hold the mouse pointer over other menu items to displaytheir contents without actually clicking on them.

In this example, if you left-click on Main, then Open Study, Edit Patient, andother commands are displayed. Left-click on the desired command in the list:for example, left-click on the Exit command to close the window.

Under the menu bar, there may be a toolbar displaying buttons representingother functions that can be performed. When you hold the mouse pointer overa toolbar button, or “hover” over it, the name of the button will be displayed.

When you left-click on the button in the toolbar, you will activate it (the back-ground color of the button may change to indicate that it has been selected). Thefunction or operation of that button can then be performed.



Window Buttons

Many windows have buttons in the bottom right corner that operate as follows:

OK—Saves selections or changes made in the window and closes the window.

Apply—Saves selections or changes made in the window; the window remainsopen.

Cancel—Closes the window without saving your changes.

Buttons that are not available for use at the time will be grayed-out, as shownwith the OK and Apply buttons in the example.

Taskbar

The taskbar is located at the bottom of the screen. It displays buttons labeledwith the names of the windows, tasks, and/or Launcher buttons that are open orrunning. The taskbar button corresponding to the currently active window or taskwill be displayed with a dark gray background, while inactive taskbar buttons willbe displayed with a light gray background.

When a window is minimized (by left-clicking on the minimize button in the topright corner of the window), the window name appears as an inactive taskbarbutton. When a window is maximized (by left-clicking on the taskbar button tobring the window back up for display), the window name appears as the activetaskbar button.
