ACUSON Redwood™ Ultrasound System Job Aid for 3D Controls

ACUSON Redwood™ Ultrasound System Job Aid for 3D Controls ACUSON Redwood™ Ultrasound System VA20 Software This document reviews functionality for both the 9VE4 and 9EC4 (Freehand or Rocked) 3D acquisitions. Always consult the user’s manual for more detailed in- formation for each transducer. Components of a Volume Rendering (VR) A B The 3D volume data set is a series of 2D images gathered over a timed • acquisition The 9VE4 is an automated mechanical calibrated acquisition of the • volume data set The 9EC4 requires a manual freehand sweep to acquire a volume • data set C VR The multiplanar renderings (MPR), are displayed on the X and Y-planes as • a pixel generated image MPR and VR planes labled. The 3D VR adds a Z-plane, creating the voxel and adding depth to the im- • age The MPRs are displayed in three planes labeled A, B and C, with the VR • (depending on image format settings selected) Image format settings. A reference dot is displayed at the green intercept point on the active • plane (i.e., A, B or C) and can be viewed in the middle of the A, B or C im- age when that plane is active Rotation of the MPR images and VR data sets occurs on all three Axes • around the intercept point X - Axis rotates horizontally • Y - Axis rotates vertically • Z - Axis rotates clockwise • Intercept point or counterclockwise A+ X - Axis around the intercept point Z - Axis Acquisition of a Volume Data Set 9VE4 Y -Axis Volume data sets acquired with the automated transducer containing Qualita- 3D tive information. Begin acquisition by: 4D Press 3D/4D control on the keyboard to enter 3D or 4D-imaging options • During acquisition, hold the 9VE4 transducer stationary, apply even pres- • sure, while positioning transducer within the center of anatomy Once 3D acquisition is started, transducer will automatically ac- • 3D/4D control is located on quire data starting from the right of centered anatomy and ending the keyboard and is activated to the left (size of acquisition is determined by angle setting) with a push. Note the page Using the smallest Region of Interest (ROI) or Volume of Interest (VOI), icon in the upper right of • acquires the smallest sweep angle possible for the best resolution image. This control allows Ensure all anatomy of interest (side to side and front to back) is in- paging through the volume • cluded within ROI data by rotating this control, when the VR is active. Each of the planes have a rotational control knob (X, Y and Z) on the keyboard.
