According to one embodiment, an MRI apparatus includes a bed, a digital processing circuit, a first antenna, first radio communication circuitry, a second antenna, second radio communication circuitry, and an image reconstruction circuit. An object is loaded on the bed. The digital processing circuit is disposed inside the bed, acquires analogue MR signals from an RF coil which receives MR signals emitted from the object, and digitizes the acquired MR signals. The first radio communication circuitry wirelessly transmits the MR signals digitized by the digital processing circuit, by using the first antenna. The second radio communication circuitry wirelessly receives the MR signals wirelessly transmitted from the first antenna, by using the second antenna. The image reconstruction circuit reconstructs image data based on the MR signals received by the second radio communication circuitry.

According to an embodiment, a magnetic resonance imaging apparatus includes a couch, a gantry, a receiving coil, a converter, and a collector. On the couch, a subject is placed. The gantry supports a static magnetic field magnet and a gradient coil. The receiving coil receives a magnetic resonance signal emitted from the subject. The converter converts a magnetic resonance signal output from the receiving coil into a digital signal, thereby generating magnetic resonance signal data. The collector collects the magnetic resonance signal data. The couch or the gantry includes a coil port that connects the receiving coil and the collector to each other. The converter is provided in the coil port or a relay device that relays between the receiving coil and the coil port.

A magnetic resonance imaging apparatus according to an embodiment includes a plurality of receiving coils, a couch, a conversion unit, a selection unit, and a reconstruction unit. The receiving coils receive magnetic resonance signals emitted from a subject. The couch includes coil ports connected to the respective receiving coils. The conversion unit is provided on the respective coil ports and converts the magnetic resonance signals that are output from the respective receiving coils to digital signals so as to generate pieces of magnetic resonance data. The selection unit selects pieces of magnetic resonance data to be used for reconstruction among the pieces of magnetic resonance data for the channels that have been output from the receiving coils and converted to the digital signals. The reconstruction unit reconstructs image data using the pieces of magnetic resonance data selected by the selection unit.

A magnetic resonance imaging apparatus collects raw data about a subject in a synchronized manner with an electrocardiographic signal of the subject. An Electrocardiogram (ECG) gating unit detects an irregular synchronization interval with respect to the electrocardiographic signal. When the ECG gating unit detects an irregular synchronization interval, a real-time sequencer controls a gradient magnetic-field power source, a transmitting unit, and the like so as to reacquire raw data that is acquired during the irregular synchronization interval.

Magnetic resonance imaging apparatus and magnetic resonance imaging method

In a magnetic resonance imaging apparatus, an event generating substrate included in a sequence control unit generates an event code to make an instruction for switching a receiving path during a scan based on scanning conditions that are set in advance of the scan. When the event code is generated, a radio-frequency switch-matrix substrate of a gantry unit switches the receiving path that connects a receiving coil and a receiving circuit.

Paving materials having excellent durability supplied to a front spreading screw 5 is prevented from dropping onto the center band of a road by a bottom plate 30, and by the rotation of the front spreading screw 5 is spread onto the two bands of the road where the left and right tires of cars make contact. In contrast, an ordinary paving materials supplied to rear spreading screw 7 is prevented from dropping onto the bands of the road with which the left and right tires of cars make contact by means of the bottom plates 32, 33 and is spread onto the center band and the outside bands of the road by the rotation of the rear spreading screw 7. Two types of paving materials spread and formed into alternating bands in this way are laid and paved at the same time by the screed 9, and as a result, a pavement with high durability can be constructed at low cost.

The invention relates to a paving materials loading apparatus. In particular, a paving materials loading feeder 16 is so disposed that a lower end 19a of a loading frame 19 thereof is connected to a receiving hopper 17, a discharge port 19c, 19d is formed in a middle part of the loading frame 19 between the lower end 19a and a discharge end 19b, and a lid 35 is provided on the discharge port 19c, 19d so as to be openable and closable. The loading feeder 16 may also be raised and lowered. The invention also relates to a paving machine provided with a front hopper 2 and a rear hopper 3, on a self-propelled vehicle 1. In particular, the paving materials loading apparatus of the above construction is mounted on the self-propelled vehicle 1 so that the discharge port 19c, 19d of the loading feeder 16 is located above the front hopper 2 and the discharge end 19b of the loading feeder 16 is located above the rear hopper 3.

A change, e.g., a cardiac arrhythmia or a motion in a subject is monitored during an acquisition of MR data in an MRI apparatus, and it is determined whether or not a change occurs in the subject. If a change occurs, after an acquisition of the MR data, the MR data is reacquired in the encoding process when the change occurs, and the MR data in the corresponding encoding process is exchanged for the reacquired MR data. An MR image is reconstructed in accordance with MR data including the exchanged MR data, and an MR image which does not include an artifact due to a change in the subject is displayed.

Method and system for acquiring MR data in MRI

A manually movable input/output peripheral device is provided which includes an input/output head or transducer which is manually movable by the user, a guide member which controls the direction of movement of the transducer, and distance measuring device. Data transfer between the transducer and a recording surface is controlled at a rate dependent on the speed which the transducer is moved across the recording surface. Thus, the device is insensitive to variations in operating speed.

Image input/output apparatus

A terminal computer used as a workstation has a display unit which displays a desired number of windows on its display screen, allowing the windows to overlap one upon another. Plural pieces of data specifying the positions and sizes of the windows are stored into a memory. Data representing the display priorities of the windows are stored into another memory. A coordinate input device, known as 'a mouse,' is manually operated by an operator, and a cursor displayed on the screen of the display unit moves with movement of the mouse on a flat surface. The most current coordinates of the cursor on the screen are stored as present-cursor position data into a memory. A window presentation controlling section is provided for comparing the present-cursor position data with the positions and sizes of the windows. When the cursor is detected to have moved into one window on the screen, the window presentation controlling section controls the display unit to automatically move this window in front of the other windows on the screen. In this case, the frontmost window is entirely visible, while the other windows are hidden at least partially behind that window.

Document image data stored in an image memory with a large memory capacity capable of storing larger data than the number of picture elements of a display unit is accessed and read out by using a mapping memory which stores the address data to specify the memory locations of picture element data groups in the image memory. The document image data read out are edited, and then are seen as document images by the display unit.

Image display control apparatus

A memory system includes a memory which consists of a plurality of bit memory cells each capable of being independently accessible and of storing bit data in at least a first and a second different predetermined bit width access mode. A multiplexer and address decoder are provided together with a bit width register for producing first and second write control signals corresponding to the first and second access modes respectively for enabling writing within the independently accessible memory cells of data having respectively first and a different second bit width.
