Sampling of the echo occurs during the frequency encoding steps and the number of samples per TR is dictated by one dimension of the matrix (typically the larger dimension because this can be done quickly). Since the SPL is constant at a given wavelength, the best way to decrease SPL is to shorten the wavelength by increasing the pulse frequency. What is the activity limit for a Very High Radiation area in Nucs? What is the spatial resolution of computer tomography? AEC is used in radiography to adjust mA via overall exposure time, and ABC is used in fluoroscopy to adjust kVp, mA, or both during electronic mag (zoom). What activity of Ga-67 is considered a major spill? Use these flashcards to support what you know about speech pathology and to learn more about this very helpful profession. The Radiologic Sciences B.S. Feel absorbed dose over 50 mGy during the 2nd to 15 week of gestation. What is the spatial resolution of digital radiography?

Core radiology exam boards board radiology gi gastrointestinal flash cards flashcards flashcard Learn with flashcards, games, and more — for free. Increasing the flip angle in GRE will do what to T1 weighting? Leakage radiation from x-ray house measured at 1m must not exceed what level? What is the relationship between energy (kVp) to linear attenuation coefficient and half value layer? Fat is very bright on T1, therefore it has a short T1 time, which also means that it recovers it's longitudinal magnetization the fastest. What type of CT kernel is used for soft tissue vs bone? Lower mA (5 instead of 500), same kVp (50-120), smaller focal spot (0.3mm). When filling K space during single spin echo imaging, what is the role of frequency encoding steps and phase encoding steps?
