PURPOSE: To achieve a reduction in a cost and a smaller size of the apparatus without causing a trouble in a simultaneous processing to be conducted normally by arranging an operation console for a main body and an operation console for diagnosis connected to a common memory separately and switching circuits connected separately between image display circuits in two image computing systems and monitoring devices attached to the respective operation consoles.

CONSTITUTION: When a measurement processing for a subject or an image analysis processing on an operation console 12 for a main body and a diagnostic analysis processing on an operation console diagnosis are performed simultaneously, an image computing system connected to a measuring device 18 for the subject performs the measurement processing for the subject or the image analysis processing. In the other image computing system, information of the operation console 13 for diagnosis is received through a common memory 11 to perform the diagnostic analysis processing the results are displayed on a monitor device 15 on the side of the operation console 13 for diagnosis through switching circuits 16 and 17.
