A medical imaging diagnostic apparatus is maintained by means of a remote computer connected to a communication line. This maintenance includes: generating log data concerning a use state of a medical imaging diagnostic apparatus; transmitting the thus generated log data to the remote computer via the communication line; storing the thus transmitted log data as data that configures a database on the remote computer; and analyzing the use state of the medical imaging diagnostic apparatus so that the use state can be displayed based on the stored log data.

Delay time data for using the transducers arranged within a probe, for transmitting and receiving an ultrasonic beam, is stored in a memory. The amount of this delay time data is less than that required for using all transducers. The delay time data stored in the memory is interpolation-processed, thereby providing additional delay time data. The sum of the delay time data stored in the memory and the additional delay time data obtained by the interpolation-processing suffices to use all the transducers incorporated in the probe.

Method and system for interpolation-processing delay time data

An ultrasonic imaging apparatus includes a transducer probe having a plurality of transducer elements, an impedance converter provided in the transducer probe, a signal processor, and a signal cable connected between the signal processor and the transducer elements via the impedance converter. The impedance converter is a transistor emitter follower having an emitter resistor. The emitter resistor is not provided within the probe, but connected between the output terminal of the signal cable and the input terminal of the signal processor.

In a digital scan converter, a vector data generator is provided. When the scanning mode is selected, the predetermined vector data adapted to the selected scanning mode is generated from the vector data generator. This vector data is temporarily stored and then used when the actual scanning commences.
