Oct 17, 2022 · The optimal imaging protocols should be developed and established with the help of a medical physicist to obtain consistently high image quality at the minimum possible radiation dose. The images should be properly compressed for transmission and storage without loss of significant clinical data.

Oct 4, 2017 · In practice, it involves compromising between the image quality and dose to the patient; the dose should not be higher than necessary to achieve an image quality (or diagnostic information) needed for the clinical task. Monitoring patient dose is a key requirement toward optimization.

Jun 14, 2018 · The paper also examined elements of best practices for digital image quality and dose reduction techniques in digital radiography (DR) from a radiographer perspective. In 2018, the ASRT convened a new workgroup to update and revise the 2012 best practice recommenda-tions.

- Standard CT dosimetry phantoms consist of cylindric acrylic phantoms with holes for dosimeter insertion at various locations. The 2 sizes are 16 cm in diameter to represent heads and small pediatric bodies and 32 cm in diameter to represent adult bodies.
- Phantom insert to hold TLDs used to measure dose profiles. TLDs are close together within x-ray primary beam and are farther apart to measure profile tails.
- Example of doses measured by TLDs inside phantom for a 10-mm slice thickness, plotted as function of TLD position along z-axis. This type of plot is referred to as a dose profile.
- Cumulative dose from a series of contiguous slices is known as multislice average dose (MSAD). Dose-profile tails extend quite far from center of x-ray beam and thus contribute radiation dose to nearby slices.
Apr 1, 2023 · Overexposure without effective improvement in image quality can produce high dose levels that adversely affect both diagnostic radiology efficiency and health; therefore, experimental data analysis is a useful, ongoing process for providing information about the adequacy of radiation exposure.
