Patent ID: 7224770

Claim:
An x-ray apparatus comprising: a radiation source; a voltage generator connected to said radiation source for setting at least one first parameter for operating said radiation source to emit x-rays; a digital solid-state radiation detector disposed to detect said x-rays emitted by said radiation source for a first image acquisition; and a control device connected to said voltage generator that controls said voltage generator to set at least one second parameter to operate said radiation source for a second image acquisition by said radiation detector successively following said first image acquisition, said control device also determining a waiting time between said first and second image acquisitions dependent on at least one of said at least one first parameter and said at least one second parameter, using a correlation table stored therein containing predetermined waiting times correlated with said at least one of said at least one first parameter and said at least one second parameter, each predetermined waiting time having a duration that, for said at least one of said at least one first parameter and said at least one second parameter, has been predetermined to at least minimize artifacts in said second image acquisition due to persistence of charge in said radiation detector from said first image acquisition.
