System Overview 0 Basic Windows Operations
Q54-53287v4
The Oas is MRI System is based on Microsoft Windows and uses many standard
Windows functions and commands. lfyou are familiar with Windows, you
will find that the Oasis MRI System windows and menus operate in a way
similar to those of other Windows-based applications. If you are not fam iliar
with Windows, make sure that you review the information in this section about
general Windows operations.
Mouse Operations
To move around the Oasis MRI System windows, you will use a mouse. The
mouse operates the pointer that appears on your computer screen, as shown in
figure 3-16.
Pointer-Marker that moves on the screen when the mouse is moved. Normally, it is an arrow. However, its shape may change depending on the operation.

Mouse Buttons and Scroll Wheel Functions
You will use the left mouse button, the wheel button (between the left and right
mouse buttons), and the right mouse button to perform various functions as
described below.
To Click an Object on Your Screen
Point to the target object (such as a button or folder displayed in the window).
Press and release the left button once so that a click sound is heard. This
operation is referred to as a "click" and is used to select buttons, menus, and
other items.
Clicking with the right mouse button is referred to as a " right-click" .
Right-clicking a target object (a series, a n image, or similar item) may display
a sho1tcut menu o r submenu of tasks or commands. These menus wi ll vruy,
depending on the target object, and are useful for completing tasks quickly.
To Double-Click an Object on Your Screen
Point to the target object, then quickly press and re lease the left nnouse button
twice in rapid succession so that a click-click sound is heard. This operation is
referred to as a "double-c lick" . Double-c licking can be used to open folders and
perform other operations.
To Drag an Object on Your Screen
Point to the target object, hold down the left mouse button, move the mouse to a
new location and then release the mouse button. This operation is refened to as
a "drag", and is used for operations such as moving items to different positions
o r loading output series to be used as input images. Perfo rming the same
sequence of steps, but using the right mouse button is referred to as a "right
drag" .
To Move Up and Down in the Windows
The wheel button is used for moving up and down (scrolling) in the various
computer windows. Using the wheel button is particula1·1y he lpful when viewing
images in the viewports. Rotate the wheel button forward to scroll up in the
document o r window. Rotate the wheel button backward to scroll down in the

Menus and Toolbars
Many windows will have a menu under the title bar. This menu is a list of
various operations that can be performed on that window. When you click a
menu (thus "opening" the menu), the commands that can be selected are listed
below that menu. Once a menu is opened, you can point to other menus to
display their contents without actually clicking them.
J n figure 3- 18, if you open the Main menu, Edit Patient, Save Image, and other
commands are displayed. Click the desired command in the list. For example,
Click Exit to close the window.
Figure 3-18. Typical Edit menu commands.
Under the menu bar, there may be a toolbar displaying buttons representing
other functions that can be performed (figure 3-19). When pointing to a tool bar
button, the name of the button will be displayed in most cases.
When the tool bar button is cl icked, you activate it (the background color of the
button may change to indicate that it has been selected). Cl icking a toolbar
button accomplishes the same result as selecting a command from a menu.
