Diagnosis Mode Types and Control
Diagnosis Mode Types
This product supports a variety of diagnosis modes including Basic Mode, Combined Mode,
Multi-Image Mode, and 3D Mode.
Basic Mode: Consists of different modes, each of which has a specific usage and function.
By default, 2D Mode is applied together with other mode.
Combined Mode: For an image, two or three Basic Modes are applied at the same time.
By default, 2D Mode is applied together with other mode. An image is viewed in a single
screen.
Multi-Image Mode: The screen is divided into two (dual) sub screens, each of which is
used to view an image. Since each sub screen can display a different image, it can be a
very useful feature, allowing multilateral views of an organ.
3D Mode: Freehand 3D images can be obtained.
The types of diagnosis mode that are available with the product are shown below:
