摘要： PURPOSE:To plot the motion part of the heart and the blood vessel wall, etc., in a body to be examined without using a contrast-medium by displaying simultaneously a tomography image and a difference image on the same screen of an image display means by image data from a selecting means for selecting and outputting one of tomography image data or difference image data, in accordance with a display period of an image display means. CONSTITUTION:By a selecting means 7 provided on an output side of a difference image data generating means 4, tomography image data Da outputted from a tomography scanning means 5 and difference image data Db outputted from a difference image data generating means 4 are inputted, one of the tomography image data Da or the difference image data Db is selected and outputted in accordance with a display period of an image display means 6, and the image display means 6 inputs these image data, by which a tomography image Ia and a difference image Ib can be displayed simultaneously on its same screen. In this case, by the difference image Ib, the motion of the motion part of the heart and the blood vessel wall, etc., in the body to be examined can be plotted without using a contrast-medium.

摘要： PURPOSE:To obtain a medical diagnostic device whose diagnosing efficiency is enhanced, by indicating characters through a simple manipulation, following a varying condition of a diagnosing image, and by automatically erasing the image. CONSTITUTION:There are provided a memory 10 for storing beforehand therein a notation, a phrase or the like together with a designated position thereof, and a keyboard 8 for reading the notation, the phrase or the like from the memory 10, and means for erasing the indicated notation or the like after a predetermined time elapses. Accordingly, the operator has to only operate a key simply, following a variation of a diagnosing image even though the variation is abrupt.

摘要： PURPOSE: To observe two images in comparison in an ultrasonic diagnostic apparatus by reproducing the control image related to a tomographic image to match a cardiac time phase thereof displayed in a real time synchronizingly with a real time image and displaying it on a screen of the same image display means. CONSTITUTION: A plurality of memory sections 3a and 3b for recording tomographic image data of an examinee and cardiac time phase information of an organic wave are arranged in parallel between an ultrasonic transmitting/receiving section 2 and a DSC4. A real time image and a data of cardiac time phase are recorded into at least one of the plurality of memory sections 3a and 3b while a control image and a data of the cardiac time phase related to the real time image are recorded into other memory sections. Thus, by an operation input to a control/graphic section 8, the memory sections are directed to start reproduction from a time phase traced back by a specified time phase from a specific time phase of the organic wave detected with an organic signal detecting section 5 or from a time phase elapsed by the specified time phase therefrom, and the control image is reproduced synchronizingly with the real time image to match the cardiac time phase of the real time image and displayed on a screen of the same image display device 9.

摘要： PURPOSE:To grasp heart phase at the same time while observing tomographic images, by storing color phase scale as well as storing the color phase information of a biological signal while synchronizing with output data from a memory part and displaying a color phase indication of a biological wave from retrospective phase to progressive phase on a part of an image. CONSTITUTION:Image data are read sequencially with time lag from a cinememory 4 and color phase information are read from a color data memory 13 while synchronizing with that reading timing and sent to a composing part 9. The tomographic image data from DSC 5, graphic data from a graphic memory 8, color phase information from the color data memory 13, and color phase scale data from a color phase scale part 14 are composed with each other in the composing part 9, and are thereafter A/D converted and the tomographic images, electrocardiographic pulses, and color phase scale are superposed and displayed on one display. Thereby, the heart phase on the electrocardiographic pulses can be grasped at the same time while observing the tomographic image at realtime by means of color variation of the background part of the tomographic image.

摘要： PURPOSE:To enable the automatic detection of the generation of an irregular pulses in the moving section within a testee body and the immediate observation of the movement before and after the generation of the irregular pulse. CONSTITUTION:An irregular pulse detecting section 12 which is inputted with the biosignal from a biosignal detecting section 6 and detects the generation of the irregular pulse in the testee body is provided. A control section 9 over the entire part is inputted with the detected irregular pulse generation signal S4 and controls the signal so as to reproduce the image data from the time phase going back to the past by as much as the prescribed time phase from the time phase when the irregular pulse is generated. As a result, the generation of the irregular pulse of the testee body is automatically detected and the movement before and after the generation of the irregular pulse is immediately observed.

摘要： PURPOSE:To connect aliasing waveforms, by providing the second address controller for an alternate mode in a D/A converter part in parallel to the first address controller for controlling the writing address to a memory circuit. CONSTITUTION:A D/A converter part 8 stores the data of a Doppler image analyzed in frequency by a frequency analyzing part 7 and is constituted of a memory circuit 16, the first address controller 17, the second address controller 21 for an alternate mode, a selection circuit 22 and a D/A converter 18. The selection circuit 22 connects the first address controller 17 to the memory circuit 16 at the time of a usual mode and connects the second address controller 21 to the memory circuit 16 at the time of the alternate mode. A display part 9 inputs the signal from a DSC 3 and that of a D/A converter part 8 to simultaneously display a tomographic image and a Doppler image at the time of the alternate mode.
