Show this page to the X-ray technician. Please note that you need a SPECIAL CT scan. The scanning mode should provide the necessary information without distortion to plan your MRgFUS tremor treatment with focused ultrasound!
Create a folder on your desktop, copy all the contents of the disk with the CT scan results into it.
Then the folder should be archived (compressed) with a zip or 7-zip archiver and sent to us by email mri.imcb@gmail.com or via a file-sharing service such as Google Drive or Dropmefiles.
DO NOT apply any enhancement filters on CT scans intended for use in MRgFUS neurosurgical procedures.
The CT Gantry should have NO TILT applied to it.
Slice thickness: Between 0.625 and 1.25 mm Uniform Slice Thickness Spacing: 0 mm Resolution: 512×512 Contrast Agents: none. Coverage: Full Prescription MUST cover entire skull (not limited to target area). Please ensure that the top slice is above the skull (in the air) and the lowest slice is all the way to the base of the skull. Orientation: It is favourable to align the axial CT images with the AC-PC plane and perpendicular to the midline.

All actions are performed on the scanning monitor (operator console). The first step is selecting the required patient.
2. The second step is to click ‘Raw-data’ (raw data processing). I have marked with the cursor where to click in each photo.
3. If necessary, change the slice thickness.
4. Then we change the Kernel
Finally, we press “Reconstruction” (bottom left corner of the screen).
