AP Femur

As was decided in the project scope, the group started with the AP femur. Using the techniques from the lab experiment done the previous week. It was determined that it’d be best to do a proximal AP femur that way it would be in the same position as the femur done the week prior.

 This proximal AP femur was done using the table bucky at a 40-inch SID with a perpendicular x-ray beam. The field of view started at 10x17 but was collimated to the anatomy and kept a portrait orientation.

 The techniques used were a kVp of 74 and a mAs of 8 which resulted in a DI value of 1. To lower that DI value, a 20% deduction was done on the mAs. That 20% deduction resulted in the mAs having to be lowered by 1.6 which resulted in the new mAs needing to be 6.4. Since it is not possible to put 6.4 on the console, the closest mAs was chosen to do the exposure. For the new exposure the techniques used were a kVp of 74 with a mAs of 6.3 which resulted in a DI value of 0.2, which falls into the optimal range.
