摘要： PURPOSE:To draw whole movement of moving organs without using a contrast medium by carrying out calculation for tomograph data in an inspected body including the moving texture between the images in time sequence which are obtained by the tomography scanning through the repetition in a prescribed cycle by a supersonic transmission/receiving means and generating the differential image data for display. CONSTITUTION:When the writing-in of data into the second image memory area 13b is completed with the progress of the supersonic scanning, the second image is formed. Then, a controller 17 allows the image elements of the images to correspond from the first and second image memory areas 13a and 13b, and the both memory data are read out, and outputted into a subtraction calculator 14. In the subtraction calculator 14, subtraction calculation is carried out for each image element data inputted in correspondence, and the differential data between the first and second images is outputted. data differential data outputted from the subtraction calculator 14 is analogue-converted by a D/A converter 15, and outputted into a display device 16 in succession. The display device 16 displays the inputted video signals, i.e., the differential image in brilliancy modulation.

摘要： PURPOSE:To display an elastic image showing the hardness of a living body tissue by conducting the operation between two time series tomographic images so as to measure the travel distance and displacement on the respective points on a tomographic image, measuring or estimating the pressure in the body cavity of a diagnosed region of an examinee, and operating the modulus of elasticity of the respective points on a tomographic image from the displacement and pressure to apply hue information. CONSTITUTION:A displacement measuring means 8 performs the operation between two time series tomographic images obtained by a tomographic scanning means to measure the travel or displacement of the respective points on a tomographic image. A pressure measuring means 9 measures or estimates the pressure in a body cavity of a diagnosed region of an examinee. The elastic modulus operating means 10 operates the modulus of elasticity of the respective points on a tomographic image from the displacement and pressure obtained in the respective measuring means 8, 9 to generate elastic image data. A hue information converting means 11 applies hue information to the elastic modulus image data input from the elastic modulus operating means 10. In a switching and adding means 12, the black-and- white tomographic image data from the tomographic scanning means and the color elastic image data from the hue information converting means 11 are added or switched to be displayed on an image display means 7.

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 provide an image display method not to reduce the visual field angle with the frame rate increased, recording on the cine-memory the data from the whole and the divided visual field angle at each N frame alternately and sequential-ly, and reading out the whole angle data and the divided angle data compensated with the left and right data of the previous whole angle. CONSTITUTION:The ultrasonic image data are collected in such a way that, at a certain frame F1, the data are picked up from the whole angle E, and next, in any subsequent N frames, only the data are picked up from the central angle E' of the whole angle E divided into three, and hereafter at each N frame, the data are picked up from the whole angle E and the central angle E' alternately and repeatedly, and thus arranged image data are recorded in the cine- memory. When the data of the divided areas are read out, the left and right side data from the previous whole angle E are added to all the data from the central angle E' appearing in N frames between the adjacent two whole angle E, thus the readout data for the divided areas being formed. The readout data of the whole and divided areas are recorded in and read out from an image memory 5 to be displayed as an ultrasonic image.

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.
