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

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.

Figure 3-19. Typical too/bar button detail.

Tool bar settings in the Exam window, Review Task and Post Processing tasks

can be applied globally.

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

Apply- Saves selections or changes made in the window, but the window

remains open.

Cancel-Closes the window without saving your changes.

Buttons that are unavailable for use are shown by the OK and Apply buttons in

figure 3-20.

Figure 3-20. Unavailable button detail.

Taskbar

The taskbar is located at the bottom of the screen. It displays buttons labeled

with the names of the windows, tasks, and I or Launcher buttons that are open

or runn ing. The taskbar button corresponding to the currently active window

or task will be displayed with a dark gray background, while inactive taskbar

buttons will be displayed with a I ight g ray background (figure 3-21 ).

When a window is minimized (by c licking the minimize button in the top right

corner of the window), the window name appears as an inactive task bar button.

Wl1en a window is max imized (by c licking the taskbar button to bring the

window back up for display), the window name appears as the active taskbar

button.
