Automatic dose adaptation as a function of patient body mass index in CT calcium scoring










Image Number 4 for United States Patent #7894570.

A weight (22) and height (24) of a patient who is to undergo a calcium screening examination in an x-ray diagnostic scanner (10) is used to calculate an appropriate x-ray dose in terms of tube current (mAs) for the calcium screening examination in accordance with the formula: mAs=c(BMI).sup.2, where BMI is a patient's body mass index defined as: BMI=patent weight_(patient height).sup.2.and C is a constant selected in accordance with a target required noise. In this manner, patients can be scanned with a minimum dose necessary to achieve the target noise, e.g., 20 HU. The images can be compared with earlier (and subsequent) images that have the same target noise.
