20090219020 | MAGNETIC RESONANCE IMAGING APPARATUS - When a magnetic resonance signal is received more than once, while a table (transfer unit) is moved, a gradient magnetic field is applied in the table moving direction, and an application amount (intensity and application time) of the gradient magnetic field in the table moving direction is changed every acquisition of data. As for the encoding by the gradient magnetic field in the table moving direction, a series of phase encode is performed at different positions of an examination target, unlike a conventional phase encode. Therefore, the Fourier transform cannot be applied to the image reconstruction. Given this situation, a magnetization map of total FOV of the examination target is determined in such a manner that a sum of the square of an absolute value of a difference is minimized, the difference between a received signal and a signal calculated from the magnetization map set as a variable, and then, the reconstruction is performed. Even when a size of signal acquisition area in the table moving direction is narrow, the magnetic resonance imaging apparatus of the present invention is capable of taking an image of a wide field of view at high speed, by performing the imaging while the table is moved continuously. | 09-03-2009 |
20100022878 | Ultrasonic Image Processor - Non-linear processing is performed in which noise reduction (smoothing) is serially performed for original data to reduce high-frequency noise components, the edge enhancement processing is performed for the smoothed image and, after that, noise components are reduced again. Finally, the created image is weighted-combined with the original image. | 01-28-2010 |
20100113927 | ULTRASONIC APPARATUS - A high-quality image pickup is performed even when there is a strong reflector, and image pickup and therapy are performed without reducing overall sound pressure even when there is a site which should not be exposed to a high sound pressure. Data for setting a desired beam is acquired, the position and intensity of a site to be avoided are detected from the data, the position and intensity are converted into a desired beam shape, focus data to form a beam along the desired beam shape is calculated, and the focus data is used to perform image generation or treatment. | 05-06-2010 |
20130148894 | IMAGE RECONSTRUCTION METHOD AND DEVICE - An objective is to enable calculation of a distribution of a physical property such as a density inside a measurement object, even when the distribution of the physical property value is non-uniform, within a feasible period of time without causing image deterioration due to phenomena such as refraction and multiple-reflections caused by the non-uniformity. To this end, the physical property value that makes an evaluation quantity be an extremum is outputted, where the evaluation quantity is a liner sum or a product of exponential function of: an equation residual quantity that is a residual being a difference between an operator term and an external force term of an equation of motion; a non-uniformity detection equation residual quantity that is a residual of an equation of detecting the non-uniformity of the physical property value from a matching degree of solutions of the equation of motion under two types of boundary conditions; and a conditional equation residual quantity that is a residual of a constraint condition. | 06-13-2013 |
