Introduction and Importance of X-ray Physics

In this section, the speaker introduces the importance of understanding X-ray physics for radiology exams and emphasizes its significant portion in exam marks.

Understanding the Significance of X-ray Physics

  • X-rays account for over 40% of marks in radiology exams.
  • Knowledge of X-ray physics is crucial for exam success.
  • Emphasizes not neglecting the fundamentals of X-ray physics amidst other modalities like MRI and nuclear medicine.

Creating X-rays and Components Involved

This section delves into the process of creating X-rays, focusing on the components involved such as the X-ray circuit and tube.

Components Involved in Creating X-rays

  • The function of the X-ray circuit to convert low voltage current into high voltage direct current.
  • Description of the X-ray tube's role in producing electrons at the cathode.
  • Explanation of how electrons are accelerated towards the anode to produce electromagnetic radiation (X-rays).

Manipulating X-rays Exiting the Patient

This part focuses on manipulating the x-ray beam exiting the patient through filtration and collimation techniques.

Techniques for Manipulating Exiting X-rays

  • Use of filters to preferentially filter out lower energy x-rays.
  • Collimation to narrow down x-ray beam to specific areas on a patient for imaging purposes.

Discusses how x-rays interact with patient matter, detectors, and methods to improve image quality by reducing scatter.

Interactions with Patient Matter and Image Quality Enhancement

  • Explanation on how x-rays interact with patient matter through penetration, transmission, attenuation, or scattering.

For each of these we will dedicate multiple lectures and look at each process in detail. Before we do so, let's take a step back and get a birds-eye overview of the components involved in x-ray physics. ========================= SIGN UP TO MY MONTHLY EMAIL NEWSLETTER 👉 https://bit.ly/3ruLh3d *Not sure if the question banks are for you?* If you're here, you're likely studying for a radiology physics exam. I've spent the last few months collating past papers from multiple different countries selecting the most commonly asked questions. You'll be surprised how often questions repeat themselves! The types of questions asked in FRCR, RANZCR AIT, ARRT, FC Rad Diag (SA), ABR qualifying Core Physics and MICR part 1 are surprisingly similar and the key concepts remain the same throughout. I've taken the most high-yield questions and answered them in video format so that I can take you through why certain answers are correct and others are not. Happy studying, Michael #radiology #radres #FOAMrad #FOAMed
