Description

Here's how digital X-ray imaging works: X-ray generation: An X-ray machine generates a controlled beam of X-ray photons that passes through the patient's body. The X-rays are attenuated differently by various tissues, depending on their density and composition. Digital detectors: Instead of using traditional X-ray film, digital X-ray systems use electronic detectors to capture the X-ray photons after they have passed through the patient's body. There are two types of digital detectors commonly used: a. Direct digital detectors: These detectors contain a layer of material (such as amorphous selenium or cesium iodide) that directly converts X-ray energy into electrical signals. The detectors capture the transmitted X-rays and convert them into digital images. b. Indirect digital detectors: These detectors use a scintillator material (such as gadolinium oxysulfide or cesium iodide) to convert X-ray energy into visible light. The light is then detected by an array of photodiodes, which convert it into electronic signals for image formation. Image processing: The electronic signals captured by the digital detectors are sent to a computer, where they undergo image processing. The processing algorithms enhance the image quality by adjusting contrast, brightness, and other parameters to optimize the visualization of anatomical structures. Image display and interpretation: The processed digital images are displayed on a computer screen, allowing radiologists and other healthcare professionals to analyze and interpret the findings. The images can be manipulated (e.g., zoomed, rotated, or adjusted) to facilitate detailed analysis.
