Providing data to the patient
Two identical disks should be provided to the patient.
Can be burned from our disc burner. Just un-check Dicom Viewer.
Each disk should have the 1mm reformatted axial set in the correct kernel, and if the data was reformatted from a finer slice size, that original set should be burned as well.
The necessary data from the CT will be acquired from the treating facility and no additional reading is required; the imaging location can follow their guidelines in this regard.
Verification of these parameters will occur after the treating site receives the disk from the patient. This may take a few weeks. Please DO NOT DELETE ORIGINAL / RAW DATA from the modality until the image set has been verified, such as to allow for reprocessing if necessary. If requested, we will contact your center after the verification step such that you may proceed with standard steps for handling of the data. Please contact Danica Smith (786-598-8347, danicas@insightec.com) to confirm that your CT meet these requirements. If further information is needed on the protocol requirements, contact Aaron Blanke (214-422-3071, aaronb@insightec.com) or Matt Korn (214-288-6562, matthewk@insightec.com).

All sinuses are assumed to be for Complete Sinus unless ordered specifically as Limited Sinus.
Pt in Supine Position:
Position Glabella Alveolar Line horizontal/parallel to the z-axis.
No gantry tilt or rotation
Superior aspect of horizontal portion of mandible completely through vertex of cranium.
Include ears, hard palate, maxillary teeth, tip of nose, and vertex of cranium.
Tip of nose included in scan and ensure it’s the anterior point of the scan.
If possible, avoid dental work
Avoid head holder and supports in field of view

NOTES ON MEDTRONIC SINUS PROTOCOL FOR CT
ALL DISCS HAVE BEEN JPEG COMPRESSED
NON-CONTIGUOUS SPACING. NEED CONTIGUOUS SLICING. 1MMX1MM
ALL 7 DISCS
SLICE THICKNESS WAS CLOSER TO 2MM. THEY NEED 1MM OR LESS.
NEED TO KNOW THE NAME WE HAVE IN THE SCANNER SO THAT THE NAMES MATCH UP.
HI PROBABILITY THAT WE DID NOT KNOW THESE NEEDED TO BE NAVIGATIONAL.
