CBCT Spatial Resolution and Field of View
We often get questions from clinicians about which FOV or spatial resolution to select for their CBCT scans. In this series, we will delve into when to use which FOV and Resolution.
Intraoral radiography – a review
This chapter focuses on intraoral 2D radiography, namely periapical and bitewing radiographs. The table below compares intraoral radiography technology based upon the type of detector. REDUCING RADIATION EXPOSUREThe following summarises some of the ways in which dose minimisation can be…
Panoramic radiographs – a review
TECHNOLOGY Film, direct and indirect digital image receptors are used in panoramic radiography, with digital receptors becoming increasingly popular. There are a few differences with regards to the film and detector technology in relation to those employed in intraoral…
Multi-detector CT and cone beam CT
This chapter focuses on volumetric (3D) imaging; multi-detector and cone beam computed tomography (MDCT and CBCT respectively).The following table compares MDCT and CBCT technology. TECHNICAL ASPECTS MDCT machine operation should only be undertaken by an appropriately trained radiographer/radiologist.The technical…
Other advanced techniques: MRI, ultrasound and nuclear medicine *
THE TECHNOLOGY Magnetic resonance imaging The basis of MRI imaging modality is a magnetic field generated around a patient which aligns spinning nuclei, the majority of which are protons, electromagnetically with the field flux. A radiofrequency pulse is then…
Prescription and radiologic interpretation
This chapter summarises the prescription of the various imaging techniques in relation to the more common conditions/clinical situations encountered in dentistry. An introduction to the key responsibilities and principles involved in radiological interpretation is also included.Abbreviations: IOR – intraoral radiography;…
