Refer To: Basic Scan and B Mode Chapters

Automatic Tissue Optimization

2 The Automatic Tissue Optimization option, or ATO, lets you optimize the image based upon a specified region of interest or anatomy within the image in order to improve the contrast of the displayed image data. You can use the B Mode Softkey or Ellipse key to create/activate an ATO map.

1 The SmartKey lets you map another brightly backlit key’s functionality to it for ease of use. To map a key to the SmartKey, 1. Press Shift (⇑) plus the SmartKey (*) at the same time. The SmartKey blinks (if not yet mapped) and the message, ‘Select push button to emulate,’ appears. 2. Press the backlit, push-button key you wish to map to the SmartKey.

To set up ATO functionality via Ellipse, 1. Press [Code P]. Go to Page 1 of 7. Trackball down to Auto Tissue Optimization → Ellipse Key Control. Press Set to cycle through the available choices. There are three possible choices, Off, Manual, or Auto. After you make your selection, press Exit. S Off. When set to Off, the Ellipse key does not function as the ATO softkey. S Manual. When set to Manual, click the Ellipse key down to bring up an ATO ROI box that you can resize with the ROI Size key and reposition with the Trackball. Then click down on Ellipse again to create the ATO map. To deactivate this map, click up on the Ellipse key. Manual works just like the ATO softkey. S Auto. When set to Auto, click the Ellipse key down to automatically create an ATO map. The system briefly displays the ATO ROI box (default or last used ROI size and position) and automatically creates the ATO map. To deactivate this map, click up on the Ellipse key.

To deactivate the current SmartKey mapping, 1. Press Shift (⇑) plus the SmartKey at the same time. The mapped key blinks and the message, ‘Select push button to emulate,’ appears. Press the SmartKey.

To create an ATO map while in B Mode, on a live, zoomed image, or while in Multi Image, 1. From B Mode, click Previous/Next. Click the ATO ROI softkey downward. An ROI box is displayed on the image and CREATE appears on the SoftMenu in place of ROI. 2. Position and size the ATO ROI over the part of the image you want to use to optimize the ATO map. Size the ROI by adjusting the ROI Size rocker switch. Position the ROI by moving the Trackball. 3. After you have positioned and sized the ROI, click the ATO CREATE softkey downward or press Set. The system then creates the map from a combination of the current selected map plus the data within the ATO ROI. After the ATO map has been created, it is applied to the current image. An asterisk on the display indicates that the ATO map is active.

Activating/Deactivating ATO 1

To activate/deactivate ATO after you have already created a new ATO map, click up on the ATO ON/OFF softkey. To create/activate an ATO map while in CINE, press [Code A] to access the ATO Softkey and follow the instructions above. ATO is not available on archived images.
