If you find one that of your patients scans are missing a section like below there are a few possible causes.

In this graph there are breaks in each of the line graphs indicating a problem. In this case we see that the line graph of the direct temperature for both the left and right sides get very cold right before the break in the graph. You see that the direct temperatures drop below 30° C which causes the program to not display a differential. When the temperature is below 30° C you would be using unreliable data. The underlying cause of this temperature swing can be due to a patient coming in from cold weather. In this case you should allow your patient to rest and acclimate your office room temperature for approximately 15 minutes before scanning again. If this continues to be an issue the patient could have a chronic problem that needs to be corrected.

Another cause of a graph not fully being displayed is if the Segmental mode is turned on. The segmental mode allows you to scan the lower back and skip up to the cervical region.  To turn this mode off just look in the top corner of the scan screen and ensure that the [Segment] button has not been pressed.
