Abstract:
A command sequencer for a CT imaging system, the combination comprising:a memory for storing a set of commands to be performed, each command containing an x-ray command field, a data acquisition command field and a count field;logic means for sequentially reading each command stored in the memory;means responsive to the x-ray command field in a command read from the memory for producing an x-ray command signal that indicates whether an x-ray source in the CT imaging system is to be energized or deenergized;means responsive to the data acquisition command field in a command read from the memory for producing a data acquisition signal that indicates when data is to be acquired from a data acquisition system in the CT imaging system;a clock source for producing a series of clock pulses;a counter coupled to receive the count field in a command read from the memory and the series of clock pulses, and being operable to produce a count done signal to the logic means indicating the command has been performed when a number of clock pulses indicated by the count field have been produced; andthe logic means is responsive to the count done signal to read the next command.
