The ultrasound probe transmits and receives ultrasonic waves in different directions and the diagnostic apparatus body combines a plurality of images captured in the different directions of transmission and reception to produce an ultrasound image. In this process, the ultrasound diagnostic apparatus measures the temperature of the ultrasound probe to change the ultrasound transmission and reception for producing a composite ultrasound image or makes the directions of transmission and reception in the last ultrasound image in one composite ultrasound image coincide with those in the first ultrasound image in its temporally adjacent composite ultrasound image. The ultrasound diagnostic apparatus thus enables consistent ultrasound diagnosis against heat generated in the integrated circuit board of the ultrasound probe while simplifying the control of the ultrasound transmission and reception.

A patient care distribution and management system is provided. The system allows for the seamless roaming of a patient within a particular medical facility or between medical facilities. The system includes body area network (BAN) management agents which process data within specified parts of a defined operational remit of a medical facility, a BAN hub agent associated with each patient that communicates with a BAN management agent and stores patient data delivered thereto by medical telemetry monitor diagnostic devices (MTMDDs) connected to each patient. The essential feature of the system is that the BAN hub agent has relatively little processing power compared to the BAN management agent which feeds it with patient monitoring rules to monitor the patient condition and to enable the BAN hub agent to set off alarms etc. as required.
