Abstract
An x-ray system (14) reads data from a detector array (22) including detector elements (40) arranged in rows (R1-R280) and columns (C1-C1365). A first group of rows include unneeded data (R1-R127) while a second group of rows include data of interest (R128-R1152). Activation of the detector elements in relation to the exposure of a patient to x-rays to improve efficiency with which the data of interest is read is disclosed. An exposure control (34) activates an x-ray tube (15) to expose the detector to x-rays during a first time period (E1). The first group of rows (R1-R127) are activated at least partially before or during the first time period. The second group of rows (R128-R1152) are activated after the first time period. Data is read from the second group of rows after the first time period.
