METHOD AND DEVICE FOR GATHERING MORE DATA PROJECTION DRAWINGS IN CT SCANNER RESTRICTED ON DATA TRANSFER SPEED

摘要

PROBLEM TO BE SOLVED: To efficiently transfer data to an image reconstituting computer from a CT detecting device array. SOLUTION: This device selects at least two primary data elements generated at a prescribed interval in series to transfer sequences arranged in a certain order of the data elements to a second place from a first place through a communication channel including a multiplexer for selecting at least one intermediate data element generated at a prescribed interval between the primary data elements. This device estimates a numeric value corresponding to an intermediate data element against respective intermediate data elements. Respective estimate values are a prescribed function of the primary data elements just before and the primary data elements just after the inside of the sequences arranged in a certain order. The device calculates a difference numeric value to the respective intermediate data elements. The difference numeric value shows an arithmetical difference between the corresponding intermediate elements and the estimate values. The device also includes a transmitter for transmitting the respective primary data elements and difference elements along the communication channel.
