The fоllоwing expоsure fаctors were used to rаdiogrаph the lumbar spine: 300 mA, 1/5 sec., 42" SID, 90 kVp, 12:1 grid in the table, 4" OID, 2 mm focal spot size, suspended respirations In the following problems, make adjustments: 1. Change mA to 500, using the original mAs and give new exposure time [1] sec. Round to the hundredths place. 2. Change distance to 36" SID and give new mAs [2] Round to the nearest whole number. 3. Using technique from the original technique, increase kVp by 15% and give new technique, while maintaining IR exposure: kVp [3] (round to the tenths place) mAs [4] (round to the nearest whole number)
