Temporal Decimation is enabled. Temporal Decimation normalizes the frame rate of

DICOM and multimedia images from the acquisition frame rate to a frame rate of 30 FPS (frames per second). This operation is performed only on images that were acquired at frame rates above 30 FPS. The benefits of this are: re duced transfer time, smaller archived studies, and better operations with P ACS systems that have limited amounts of display memory.

contains one or more frames with measurements present, these frames will not have the measurement graphics present in the loop when exported in DICOM or multimedia format. The frames containing measurements will be transferred as single frame images with the measurement graphics visible. These images will follow the loop in which the measurements originally appeared. Using this feature, the frames containing measurements are easy to find.

Basic Setup

The Presets Menu

Presets are settings that are used to configure the system with your preferred settings as well as factory-defined settings. They are accessed from the Setup tab. The Preset feature allows a single user-defined “title” to store the presets for all transducers. When a different transducer is attached, the Cypress system automatically recalls and loads the presets assigned to that transducer. There are two types of presets:

 Factory Presets — These presets cannot be deleted and include: Factory

Defaults (default presets for all transducers); Last Power Down (a preset that holds the settings in place at the last shutdown); and Abdominal Factory Defaults (stores abdominal presets for the 3V2c and 7V3c transducers).

 User-defined Presets — These presets can be defined, edited, and deleted

by users.

NOTE The Cypress system saves the last-loaded preset which is

loaded at the next power-up.

This is the list of functions that can be stored in a user-defined preset:

1. Depth 22. Sweep Speed

2. Frequency 23. PW Range Gate Size

3. Left/Right Invert 24. PW Gain

4. 2D Gain 25. PW Baseline

5. Apex Invert 26. PW Scale
