20110240872 | RADIOGRAPHIC IMAGING SYSTEM - A radiographic imaging system includes an imaging apparatus which takes a radiographic image of a subject and outputs image data of the radiographic image; an image processing apparatus which performs image processing of at least one of an exposure field recognition process and a trimming process on the image data of the radiographic image; an image processing information storage apparatus which stores the imaging conditions of the radiographic image and image processing information which indicates the image processing and its applicable range in an associated manner; and an image processing information search apparatus which searches for image processing information according to imaging conditions of current imaging, among the image processing information of past imaging stored. The imaging apparatus changes a range of radiation exposure irradiated from a radiation source in accordance with the applicable range of the image processing of the past imaging contained in the image processing information retrieved by the image processing information search apparatus. | 10-06-2011 |
20140180090 | ULTRASOUND DIAGNOSTIC APPARATUS, TISSUE ELASTICITY MEASUREMENT METHOD, AND RECORDING MEDIUM - When tissue elasticity of a subject is measured, an ultrasound diagnostic apparatus sets a sound velocity for each of segment regions established by dividing the subject, processes reception signals output by a piezoelectric element array based on the set sound velocities, and performs tissue elasticity measurement based on the reception signals processed based on the set sound velocities. Owing to this configuration, when tissue elasticity of a subject is measured, the ultrasound diagnostic apparatus prevents the accuracy of tissue elasticity measurement from deteriorating due to image distortions. | 06-26-2014 |
20140187938 | ULTRASOUND INSPECTION APPARATUS, SIGNAL PROCESSING METHOD FOR ULTRASOUND INSPECTION APPARATUS, AND RECORDING MEDIUM - Provided is an ultrasound inspection apparatus ensuring the real-time property during ultrasound imaging, reducing the data amount to be stored, and making sound speed value correction after the imaging to allow improvement in image quality, tissue characterization, and so forth with high accuracy. The ultrasound inspection apparatus includes: a first reception signal memory storing element data; an image producer adapted to perform phasing and adding on element data based on a specified sound speed value to produce a sound ray signal, and produce ultrasound image data; a sound speed determiner adapted to determine the optimum sound speed value from a plurality of pieces of ultrasound image data produced using element data; a storage necessity determiner adapted to determine element data whether or not to satisfy a specified condition; and a second reception signal memory storing the element data as determined to satisfy the specified condition. | 07-03-2014 |
20140187952 | ULTRASOUND DIAGNOSTIC APPARATUS, SOUND VELOCITY SETTING METHOD, AND RECORDING MEDIUM - An ultrasound diagnostic apparatus performs transmission and reception of ultrasonic waves for forming focal points used to set sound velocities at predetermined timing such that sound velocities having been set for all of respective segment regions established by diving a subject are all reset every predetermined number of frames. Owing to this configuration, it becomes possible for the ultrasound diagnostic apparatus to suitably reset sound velocities of ultrasonic waves in the subject and also reduce the amount of calculation for resetting sound velocities. | 07-03-2014 |
20140187953 | ULTRASOUND DIAGNOSTIC APPARATUS, ULTRASOUND IMAGE PRODUCING METHOD, AND RECORDING MEDIUM - In an ultrasound diagnostic apparatus, when a compound image is produced, delay correction is performed on all of ultrasound images (sub frames) to be combined based on sound velocities set for respective segment regions obtained by dividing the subject. Owing to this configuration, the ultrasound diagnostic apparatus can produce a high quality compound image by spatial compounding or frequency compounding without being affected by distortion in images. | 07-03-2014 |
20140206999 | ULTRASOUND DIAGNOSTIC APPARATUS, METHOD OF PRODUCING ULTRASOUND IMAGE, AND RECORDING MEDIUM - Ultrasonic transmission and reception for sound speed setting is performed in response to an instruction to freeze, an instruction on an observation target range, an instruction to change image quality and an instruction to change an image mode, a reception signal obtained by the ultrasonic transmission and reception for sound speed setting is used to set the sound speed in a subject, and a reception signal obtained during ultrasonic transmission and reception is processed based on the set sound speed to produce an ultrasound image. Such method makes it possible to produce a high-quality ultrasound image subjected to delay correction appropriate to various operations on an ultrasound diagnostic apparatus, such as freezing and change in image quality. | 07-24-2014 |
