Determine the mAs for Grid and Non-Grid portions of the technique chart using the information provided below. You are creating a Grid/Non-Grid mAs variable technique chart for the canine/feline abdomen. You have selected a sample patient that has an abdominal measurement of 8 cm and weighs 12 kgs. Based on your machine’s mA and time settings and your patient’s weight, you chose the 3 fastest mAs settings and created 3 test radiographs. You selected the radiograph produced using (300 mA)(1/40) = 7.5 mAs. Your machine has a grid ratio of 12:1. Use the information provided below to help you. You are NOT required to show your work to receive full credit.
