Sequentially to the Axial series scanned by the “Scan Prescribed Volume” option,
additional two scans will start running on the MR. These scans are the Axial and Sagittal

6.5.4. Manual Acquisition of MR Planning Images
As an alternative option for acquiring the planning images from the Exablate workstation, you may prepare
and acquire the planning images completely using the MR workstation user interface.
1. Prepare and scan the desired planning orientations on the MR. Follow these imaging guidelines:
◼ Prescribe high quality, high resolution sets of T2w images.
◼ The Axial series should have a slice thickness of 3mm and zero spacing.
◼ We recommend acquiring images that are perpendicular to the transducer axes. It is easier to view
and comprehend the overlaying spots on such images.
2. After acquiring the scans, confirm that:
◼ The target to be treated is visualized
◼ Verify that the patient has not moved during imaging and that there are no imaging artifacts that
could influence identification of anatomy structures.
3. Press this button and open the loading form (see Figure 6-5).
4. After acquiring each of the scans (or alternatively after all were scanned), press this button.
The new series that has just been scanned on the MR will appear on the MR Series List of the
Selected Exam.
5. Click on each one of the selected series you would like to upload as Planning Images. As a default,
all images within the selected series will be used by the system.
6. If only part of the series is needed, Click the desired image numbers as follows:
◼ Select an image and then press Shift and select another image, to select any number of contiguous
images.
◼ Select an image and press Ctrl to select additional non-contiguous images.
7. The selected series will appear on the Selected Images List.
