This article describes the process of using the SOTA Hub’s filter tuner.

1. Follow steps 1 and 2 of General X-ray Image Quality Troubleshooting*

2. Using the filter tuner capture a bitewing x-ray with the relevant device selected, see Figure 1.

3. Click the “Auto Adjust” button to automatically configure gamma for this x-ray head

4. Verify the image gamma is correct. Reference Figure 4. Specifically:

   

   Figure 4

   a.       There should be nearly black/black sections between the teeth

   b.       The dentin-enamel junction (DEJ) is clearly discernible

   c.       The periodontal ligament is clearly distinguishable from the cementum and the lamina dura

   d.       The pulp horns are clearly discernable from the dentin

5. Adjust sharpness to the preference of the doctor(s) who perform(s) clinical evaluation of X-rays.

6. Save your settings.

7. Capture an image in your imaging software to ensure correct image transfer and successful saving of settings. If you notice unwanted differences between what you see in the filter tuner and what you see in your imaging software, try:
