Radiology is an essential field of medicine that uses X-rays to diagnose and treat various medical conditions. While X-rays are a valuable diagnostic tool, they also expose patients to ionising radiation, which can be harmful. Therefore, it's important to take steps to minimise X-ray dose exposure without compromising the quality of the images.

This blog will discuss how to reduce radiology X-ray doses in detail. We'll explore the different types of radiation and their effects on the human body. We'll also provide tips on minimising X-ray dose exposure while maintaining image quality.

Understanding Radiation

Radiation is defined as the movement of energy through space and matter. It can be in the form of electromagnetic waves, such as X-rays and gamma rays, or as particles, such as alpha and beta particles. Radiation has just enough energy to ionise atoms by removing tightly bound electrons.

Ionising radiation can harm living cells because it can cause DNA damage, leading to mutations and cancer. However, the effects of ionising radiation depend on the type and amount of radiation and the body part exposed.

Types of X-ray Machines

X-ray machines are classified into two types: film-based and digital radiography. Film-based X-ray machines use photographic film to capture X-ray images, while digital radiography uses digital sensors to produce images.

Digital radiography has become increasingly popular due to its superior image quality and reduced radiation exposure. Digital x-ray machines produce high-resolution images, allowing for easier diagnosis of medical conditions. Additionally, they require less radiation exposure, which minimises the risk of radiation-induced cancer.

Reducing X-ray Dose Exposure

Here are some tips on how to reduce x-ray dose exposure while maintaining high-quality images:

  1. Use Lead Aprons: Lead aprons can shield the body from X-rays, reducing radiation exposure. Ensure that the lead apron covers the entire torso and groin area. The lead apron should also be checked regularly for any defects.
  2. Collimation: refers to limiting the X-ray beam to the area of interest. Collimation reduces unnecessary radiation exposure to other body parts, which can help prevent radiation-induced cancer. Therefore, the X-ray beam should be collimated to the smallest possible size.
  3. Use High-Quality X-ray Machines: High-quality X-ray machines produce high-resolution images, requiring less radiation exposure. When purchasing an X-ray machine, consider investing in a high-quality machine that can produce clear images at a low radiation dose.
  4. Limit X-ray Exams: Limiting X-ray exams to those medically necessary can significantly reduce radiation exposure. Before ordering an X-ray exam, physicians should evaluate the patient's medical history, symptoms, and physical examination findings to determine the need for the exam.
  5. Use Shielding Devices: Shielding devices, such as Lead and gonadal shields, can reduce radiation exposure to sensitive organs, such as the thyroid and reproductive organs. When necessary, this equipment should be used.

In conclusion, reducing radiation dose in x-ray imaging is essential to patient safety and radiation protection. By understanding the principles of radiation dose measurement and the factors that affect radiation dose in x-ray imaging, radiologic technologists can optimise imaging protocols to reduce unnecessary exposure without compromising diagnostic image quality. Ongoing training, education, and compliance with regulatory standards for radiation safety are essential to ensuring the safe and effective use of x-ray imaging in modern medicine. By following best practices and incorporating patient-centred care, healthcare providers can provide safe and effective diagnostic imaging while reducing the risk of long-term health effects associated with radiation exposure.
