While taking images in Scout software, a warning displays on the screen indicating that the image exceeds the recommended value of 25% for either HOT or COLD.
Saturation of this image exceeds the recommended value of 25% warnings both HOT or COLD indicate that there is a high level of saturation in the entire viewable area of the thermal image. This includes not only the target of the image, the patient, but also all surrounding items. It is important for the user to ensure that the saturation (solid purple or solid maroon) is not present in your target skin surface prior to taking the image.
High saturation away from the target skin surface does not affect the accuracy of the measurements of the target skin surface.
Additionally, this warning does not prevent the user from capturing an image.
In Scout versions 1.14 and above, we now display the full text of this message on the thermal image. In previous versions, the warning only showed an icon until a user would hover over with their cursor. See images below:
Scout 1.15.1
Scout 1.11
If an image with high level of saturation is uploaded and saturation is detected in the area of measurement, the user will see a warning that control cannot be placed in an area of saturation.
This indicates that the area of the image where this control is placed detects a high number of either fully hot or fully cold pixels. This can also occur if a measurement object (Area of Interest, Profile Line) is placed over these areas.
SOLUTION
Check the area around the patient for cold or warm surfaces/items, ensure reasonable environment temperature (72F +/- 4F)
If the target area is solid purple and the camera was recently powered on, give the camera more time to "warm up".
If the target area is solid maroon and the camera has been powered on for a long time (4+ hours), try turning the camera off for a few minutes to let it cool down.
If none of these options resolve this issue, please submit a support ticket to https://help.woundvision.com/fix-it-now and indicate Thermal Saturation as the main issue.
