Abstract: In a superconducting coil used in an MRI apparatus, it is necessary to arrange a superconducting wire at a desired position to obtain a desired coil shape in order to obtain a temporally stable static electromagnetic field with high strength and high uniformity. A superconducting coil includes a winding frame, a spacer disposed on an outer periphery of winding frame and including a winding groove having a spiral shape and a communication groove provided between winding grooves, and includes a coil group having a superconducting wire wound in winding groove. It is therefore possible to obtain superconducting coil having a desired coil shape.

Abstract: A MR simulation apparatus according to an embodiment includes an input interface, central processing circuitry, and numerical processing circuitry. The input interface inputs a subsequence, being to be a subject of a simulation of a MR phenomenon, of a MR pulse sequence; and a plurality of isochromats having a same Bo shift at different positions corresponding to subvoxels which are segments of each of voxels related to the simulation of a MR phenomenon. The central processing circuitry determines, based on the subsequence, two or more isochromats exhibiting equivalent MR phenomenal behaviors as equivalent isochromats from the plurality of isochromats. The numerical processing circuitry collectively simulates MR phenomenal behaviors of the equivalent isochromats due to the subsequence by the same computation.

Abstract: An apparatus and method are provided to correct for time-walk errors during photon detections (e.g., detecting gamma rays). A time-walk correction is determined using measurements of energy (or charge) that apply different time windows, enabling corrections accounting for variations in the ratio between fast and slow components in the detected pulse. For example, one time window can be used to integrate the leading end of the pulse, thereby predominantly measuring the fast component, while a second window is used to integrate a trailing end of the pulse to predominantly measure the slow component. Alternatively or additionally, low-pass and high-pass filters may select the slow and fast components, respectively. The time-walk correction is a function of multiple measurements representing different components (e.g., fast and slow) of the pulse shape.

Abstract: An ultrasonic diagnostic apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to acquire a function index value of each heart chamber for two heart chambers, including the left ventricle, included in a moving image of a heart. The processing circuitry is further configured to generate an image by superimposing a range suggestion image on a two-dimensional coordinate space. In the two-dimensional coordinate space, the processing circuitry allocates the function index value of the each heart chamber to each display dimension corresponding to the each heart chamber and defines the functional index value of the left ventricle as an output coordinate. In the range suggestion image, the processing circuitry colors the range suggestion image according to predetermined normal range and abnormal range for the functional index value of the left ventricle.
