ULTRASONIC DIAGNOSTIC APPARATUS

PROBLEM TO BE SOLVED: To attain the start processing of an ultrasonic diagnostic apparatus, which corresponds to the temperature environment.SOLUTION: When the ultrasonic diagnostic apparatus is switched into a power ON state, a BIOS is started in a center control part 20 thereby to ascertain temperature in basic processing by the BIOS. That is, it is ascertained that the measurement result of temperature to be obtained from a temperature sensor S via a sensor IF part is within an appropriate temperature condition or not. When it is determined that the temperature is appropriate as a temperature ascertainment result, an OS stored in the hard disk of the center control part 20 is loaded to start the OS. When the OS is started, various kinds of software stored in the hard disk of the center control part 20 are started. Thus, control processing is started with respect to a transmission/reception part 22, a beam former 24, a cine memory 26, and a scan converter 28.
