Final answer:
Three methods that can improve image quality and decrease patient dose in medical imaging are beam restriction, low kilovolt and high milliampere-second factors, and grids.
Step-by-step explanation:
Three methods that can improve image quality and decrease patient dose in medical imaging are:
- Beam restriction: By limiting the size of the x-ray beam, beam restriction reduces scatter radiation, resulting in clearer images and lower patient dose.
- Low kilovolt and high milliampere-second factors: Using lower kilovolt settings and higher milliampere-second factors can improve image quality while reducing patient dose. This is achieved by optimizing the x-ray technique to reduce unnecessary radiation exposure.
- Grids: Grids are positioned between the patient and the x-ray detector to absorb scattered radiation, improving image quality by reducing scatter and increasing contrast. This allows for better visualization of anatomical structures and reduces the need for repeat imaging.
