What is the difference between oral ct and ordinary ct?

Oral CT and general CT mainly have the following differences:

1. Different scanning ranges

Oral CT usually only scans maxillofacial related anatomical structures, and the scope is smaller.

Generally, CT needs to scan a wider range, including the head and neck and many areas of the whole body.

2. Different resolutions

Because of the small scanning range, oral CT can adopt higher resolution and clearer images.

Generally, the resolution of CT is low.

3. Different equipment

Oral CT usually uses a specially designed oral scanner.

Ordinary CT adopts standard whole-body CT scanner.

4. Different radiation doses

Oral CT only scans the local area, and the radiation dose is low.

Generally, the dose of CT radiation is relatively large.

5. The purpose of inspection is different.

Oral CT mainly examines the condition of teeth.

Generally, CT mainly screens the brain and other systemic diseases.

6. Image post-processing is different

Dental CT has special post-processing software for dental images.

Generally, CT is mainly used to observe human soft tissues.

To sum up, there are great differences between them in equipment and application. Dental CT can provide more accurate dental images.
