ACUSON Redwood™ Ultrasound System 9EC4 Freehand 3D Acquisition Job Aid

ACUSON Redwood™ Ultrasound System 9EC4 Freehand 3D Acquisition Job Aid ACUSON Redwood™ Ultrasound System VA2.0 Software This job aid reviews the 9EC4 transducer and its ability to acquire a Freehand 3D volume using the Gynecology (GYN) preset. This is a manual 3D volume acquisition method and does not give Quantitative data. Always reference the user’s manual for more detailed instructions. Getting Started: The 9EC4 can be used for any endocavity exam and delivers excellent 2D imaging, but our discus- sion focuses on the GYN 3D volume acquisition. Follow these instructions before entering the 3D mode: Evaluate the anatomy to be acquired (i.e., larger volumes need longer sweep times and a • greater Angle, while smaller anatomy require less sweep time and a smaller Angle). o Adjusting the Angle changes the sweep angle in degrees or adjusts the elevation of the 3D volume. Acquisition angles available are 30, 60, 90, 120, and 150 degrees of elevation. o Moving anatomy produce stitching lines within the multiplanar rendering (MPR) images and the volume rendering (VR). Avoid moving anatomy, (i.e., rolling bowel, active fetus, etcetera). Stitching lines are an interruption of the displayed data. Optimize the 2D image with overall gain, decibels, contrast, tint, etcetera. The better the • 2D image, the better the 3D volume. o When entering the 3D option, a slight overall gain increase may be needed because of the added elevation of the acquired volume data. Press the 3D/4D control on the control panel to enter the 3D application, • (4D is not available with the 9EC4 transducer). 3D 3D/4D Setup: 4D Outlined in the green box • Surface gives visualization of A 2 "gEC GYN 9VE4 + Add Exam Workflow varying opacities within the Patient 3D/4D Setup volume.

There are three settings available; Low • generates a low resolution image with the fastest sweep speed, Mid delivers an optimized image with a moderate sweep speed, and High provides a high-resolution image with the slowest sweep speed. Angle – control determines the Angle or depth of the sweep. The sweep angle indicates the • elevation of the 3D volume and corresponds to the MPR B plane. This information displays in degrees and can be viewed in the Rocked icon on the bottom right of image. Understanding the ROI and VOI: Activation of the 3D/4D control displays a region of interest (ROI), the volume of interest (VOI), and a Cut Line overlay on the image. Understanding these emblems is important and are identified by the associated number on the image: 1 1. Cut Line – defines the face 2 9EC4 GYN TIB 0.42 of the volume.
