CT protocols
Download the protocol for your task and hand it to the CT department. Whether a device can be designed depends on the quality of the study.

A single page of parameters: slice, field of view, reconstruction. Print it and hand it to the radiographer.
Cone-beam CT distorts bone density and produces metal artefacts — such data cannot be used to reliably reconstruct the defect geometry or calculate the fixation zones. MSCT is required — multislice CT. The exception is certain dental tasks; the acceptability of CBCT is agreed with an engineer before the data is acquired.
Thick slices smooth the edges, so the device will fit with a gap. The defect margins must be legible on the study, not inferred by the engineer.
Bone density determines where the screws will sit. CBCT distorts density, so fixation calculated from such data is unreliable.
If the data is insufficient, the patient will have to be rescanned: a delay and additional radiation exposure.
The complete series, uncompressed. Not JPEG, not screenshots, not photos of a screen.
Any file-sharing service. There is no need to upload the DICOM through the form — a link is enough.
Where possible, de-identify the study and do not attach unnecessary patient data.
Primary axial images in DICOM format, thin slices, full coverage of the region of interest and no gross artefacts. Do not send only JPEGs/screenshots or 3D reconstructions instead of the original DICOM.
MSCT is preferable for most tasks; CBCT can distort density and produce artefacts. Whether CBCT is acceptable for particular dental tasks is confirmed on a case-by-case basis.
DICOM in an archive (.zip/.rar) as a cloud link — via the form or to info@bonabyte.net. Where possible, de-identify the study before sending it.
Use the scanner's metal artefact reduction function and keep the primary axial series. If artefacts are pronounced, an engineer will advise how to rescan the region of interest.
The information on this website is intended for healthcare professionals and does not constitute medical advice, a public offer or a guarantee of clinical outcome. Bonabyte devices are custom-made medical devices designed for a specific clinical task; their applicability depends on the CT data, the anatomy, the condition of the soft tissues, the surgical access and the operative plan. The final decision on the use of a device is made by the treating physician. Contraindications exist and an individual assessment of the clinical situation is required.
