Study Notes
Course Overview
- The course is presented by Dr Lee Feinberg, a Consultant Dental and Maxillofacial Radiologist.
- The course covers topics on x-ray production, use, interpretation and safety
- The course consists of 8 modules:
- What is an x-ray?
- How are x-rays produced?
- What happens when x-rays hit you or the patient?
- How much radiation do you use?
- How do you create an x-ray image?
- How do you limit dose and what legislation must you comply with
- What is an x-ray image?
- The anatomy of the maxillofacial skeleton and an introduction to radiological interpretation
Diagnostic Imaging in Dentistry
- X-rays or radiographs are used to image teeth
- Cone Beam CT scans allow for 3D imaging of the head and neck
What are X-Rays?
- X-rays are a type of wave
- Specifically, they are a type of electromagnetic wave
Electromagnetic Radiation Waves
- Electromagnetic radiation waves have electric and magnetic fields
- These fields vibrate at right angles to one another and the direction of the wave
- They carry energy from one place to another
- Their interaction with matter is dependent on their wavelength and frequency
Electromagnetic Spectrum
- The spectrum consists of Radio, Microwaves, Infrared, Visible light, Ultraviolet, X-rays, and Gamma rays
X-Rays
- X-rays are invisible
- They are used in diagnostic imaging to produce images of patients
- The amount detected by the detector dictates the image darkness
- More x-rays passing through the patient = darker image (radiolucent)
- Fewer x-rays being absorbed = lighter image (radiopaque)
Ionising Radiation
- The energy of a photon is determined by its frequency
- Higher frequency photons have greater energy
- UV photons, X-rays, and Gamma rays are ionising radiation types
- Ionising radiation can cause harm to the patient
