![]() Conversely, when the quantity of x-rays is decreased, the exposure to the IR decreases. Once the anatomic part is adequately penetrated, as the quantity of x-rays is increased, the exposure to the IR proportionally increases. Study with Quizlet and memorize flashcards containing terms like Flexible piece of plastic that is constructed to withstand heat, moisture, & chemical exposure and provides strength & stable support for the film emulsion. If you had a diagnostic X-ray before you knew you were pregnant, talk to your health care provider. The product of milliamperage and exposure time has a direct proportional relationship with the quantity of x-rays produced. In addition, if you have a child who needs an X-ray, don't hold your child during the exam if you are or might be pregnant. Depending on the circumstances, it might be possible to postpone the X-ray or modify it to reduce the amount of radiation. Double exposure results when the receptor is exposed twice, and two images appear superimposed onto each other. But the typical dose of a single radiation exposure associated with a diagnostic X-ray is much lower than the high dose associated with these complications.īefore having an X-ray, tell your doctor if you are or might be pregnant. Exposure between weeks 8 and 16 might increase the risk of a learning or intellectual disability. However, these dose levels aren't used in diagnostic imaging.Įxposure to high-dose radiation two to eight weeks after conception might increase the risk of fetal growth restriction or birth defects. ![]() 24 In these methods, instead of expensive and high-precision gratings, sandpaper is employed as. 1 Recently, speckle-based x-ray imaging methods, which are sensitive to phase gradients, have received increasing attention as they entail a simple experimental setup. Exposure to extremely high-dose radiation in the first two weeks after conception might result in a miscarriage. X-ray phase-contrast microtomography is a useful tool for the non-destructive three-dimensional (3D) imaging of low-Z materials. The risk of harm to your baby depends on your baby's gestational age and the amount of radiation exposure. The exception is abdominal X-rays, which expose your belly - and your baby - to the direct X-ray beam. Most X-ray exams - including those of the legs, head, teeth or chest - won't expose your reproductive organs to the direct X-ray beam, and a lead apron can be worn to provide protection from radiation scatter.
