uncollimated造句

• The specific ( radiative ) intensity is suitable for the description of an uncollimated radiative field.
• The spectral radiance ( or specific intensity ) is suitable for the description of an uncollimated radiative field.
• Quantitative phase retrieval was also demonstrated with ( uncollimated ) incoherent sources, showing that in some cases results analogous to the synchrotron gold standard can be obtained . results in a number of advantages, which include reduced exposure time for the same source power, reduced radiation dose, robustness against environmental vibrations, and easier access to high X-ray energy.
• The effective dose of radiation for an adult given 370 kBq of SeHCAT is 0.26 mSv . ( For comparison, the radiation exposure from an abdominal CT scan is quoted at 5.3 mSv and annual background exposure in the UK 1-3 mSv . ) Measurements were originally performed with a whole-body counter but are usually performed now with an uncollimated gamma camera.
