Abstract: A medical image generation apparatus is communicably connected to an information processing apparatus which receives inputting and performs displaying of information regarding a test object. The medical image generation apparatus includes: an image data generation section to generate image data of the examination region of the test object; and a control section to request the information processing apparatus to transmit test-object specifying information for specifying the test object, to receive the test-object specifying information transmitted from the information processing apparatus, to obtain test-object information corresponding to the received test-object specifying information from a predetermined test-object information storage section, and to correlate the obtained test-object information to the image data created by the image data generation section.

Abstract: The transmitting section of an ultrasound image diagnostic apparatus outputs a square pulse signal to allow a transducer to generate transmission ultrasound. The transmitting section sets the duty ratio of a pulse signal so that one of peaks of the first step response of the transducer which is generated when a change is made to voltage of the pulse signal overlaps with one of peaks of the second step response of the transducer which is generated when another change is made to the voltage of the pulse signal.
