Corridor4DM: How to Use Manual Mode

This document will aid the user in performing manual adjustments (Manual Processing
Mode) to original patient data or 4DM Results while performing Quality Assurance (QA)
on the MI Processing Screen. The Manual Mode icon on the MI Processing Screen replaces the previous Setup screen. This mode enables changes to LV Centering, Tilt and Orientation, and both basal and apical limits. This should be performed only when necessary,
such as poor left ventricular orientation or non-tracking contours.

Corridor 4DM: How to Use Manual Mode SPECT & SPECT/CT This document will aid the user in performing manual adjustments (Manual Processing Mode) to original patient data or 4DM Results while performing Quality Assurance (QA) on the MI Processing Screen. The Manual Mode icon on the MI Processing Screen replac- es the previous Setup screen. This mode enables changes to LV Centering, Tilt and Orien- tation, and both basal and apical limits. This should be performed only when necessary, such as poor left ventricular orientation or non-tracking contours. For more information on the MI Processing Screen, please see the job aid “MI Processing Screen – How to Verify Auto-Processed Results.” Evaluate Need for Manual Processing 1. On the MI Processing Screen a. Review auto-processed data in QA (Quality Assurance) Mode.. b. Verify LV contours track the LV properly. c. If contours are not tracking click the Manual Processing Icon to go into Manual Processing Mode. Figure 1: Manual Processing Icon 2. Within Manual Processing Mode a. Check to see if changes to centering, orientation, and axial limits are necessary to improve LV contour tracking. b. If no changes are required, click the Return icon to return to QA Mode on MI Processing Screen. Figure 2: Return Icon c. If changes are necessary, continue to next section Manual Processing Mode.

LV Centering To adjust center position, left mouse click and drag the white crosshairs in the center of the short axis (SA slice) to desired position. HLA and VLA centering is updated when basal and apical limits are adjusted. SA Slice SA Slice Figure 4: Improper and Proper SA LV Center 2. LV Tilt and Orientation To adjust the orientation of the LV, left click mouse pointer on the circular reorientation handles (See 1 and 2 on Figures 5 & 6) and drag to desired tilt and orientation. Apex of VLA slices should point to 3 o’clock position and apex of HLA slices to 12 o’clock. 26 30 13 1 O O VLA Slice VLA Slice Figure 5: Improper and Proper LVA Orientation Siemens Healthineers Services Page 2 of 5 © Siemens Healthcare GmbH, 2017 Job Aid | Corridor 4DM: How to Use Manual Mode Effective Date: 12/17/2018 | HOOD05162002918647 2 HLA Slice HLA Slice Figure 6: Improper and Proper HLA Orientation 3. LV apical and basal limit If necessary, changes to these limits can be made by left mouse clicking and dragging the vertical sliders. The apical limit should be placed 1-2 pixels into the myocardium (mid-apical level) (see 1 on the right image of Figure 7). The basal limit should be placed at the end of the left ventricle where the color drops to <50% of the mid-ventricular in- tensity (see 2 on the right image of Figure 7). 31 12 - 00 O 2 1 VLA Slice VLA Slice Figure 7: Improper and Proper Basal and Apical Limits Hint: It may be helpful to change the color LUT to QGS Step 10 for easier identification of the 50% color drop off point. 13 VLA Slice Figure 8: QGS Step 10 Color LUT with proper basal and apical limit placement. 4. Process After all adjustments have been made, click the Process Icon (Figure 9) to apply 4DM algorithms using the new changes to orientation and limits. Updates to perfusion and functional results are immediately available for review on the QA Mode screen.

Reset Mode If data needs to be reprocessed manually, click the Reset icon (Figure 10). The Reset but- ton goes directly to the manual processing screen so the data can be reprocessed. This will overwrite previously generated results and results files.
