Input Images and landmarks Section
Q: What is the format of the image data to be applied for CephSmile?
A: Images data formats for CephSmile can be described in this table as follows:
| Type of Image Data | Image Formats |
|---|---|
| Lateral and Frontal Cephalograms | JPEG or BITMAP of 8 bit, 24 bit and 32 bit type |
| Lateral and Frontal Photographs | 24 bit JPEG or 24 bit BITMAP |
| Dental Model | 24 bit JPEG or 24 bit BITMAP |
Q: How to prepare lateral and frontal cephalograms to gain optimal results?
A: For lateral cephalograms, keep the width larger than the height. For frontal cephalograms, keep the height larger than the width. If it is necessary to keep the height of lateral cephalograms larger than the width, ensure that all 79 lateral landmarks including Porion, Basion and Soft Tissue Nasion can be located within the lateral cephalograms.
Q: How many landmarks are required for lateral and frontal cephalograms to be defined before executing cephalometric analyses?
A: 42 or 79 landmarks for lateral cephalometric analysis and 57 landmarks for PA analysis (frontal cephalometric analysis).
Q: Is CephSmile able to accept other image data formats?
A: CephSmile will only accept JPEG or BITMAP image formats.
Q: How can I obtain the digital cephalograms if the digital dental X-ray machine is not available?
A: The ways to obtain the digital cephalograms without if the digital dental X-ray machine can be described as follows:
- Digital scanners with a capability to handle the transparent sheets which allow the users to digitize the lateral and frontal cephalogram films to obtain the digital radiographic files.
- If the digital scanner with a capability to handle the transparent sheets is not available, the alternative is to construct the lamp table or the light box before putting the lateral and frontal cephalogram on the light box and use a digital camera to digitize the analog cephalogram.
Q: What are the criteria for a digital camera to be used along with the light box as the substitute of the digital scanner with a capability to handle the transparent sheets?
A: The digital camera to be applied with the light box should have the optical magnification of at least 10x or better along with the specially designed tripod with clamp to allow the stability while taking a digital photograph of the cepalogram on the light box.
