Abstract: An imaging apparatus and method of the same, able to combining an image of a virtual object in an image of a real space so that the virtual object is virtually located in the real space at a desired position and at desired angles and able to easily set the position, posture, etc. of the virtual object, using a circular marker having two semicircular portions of first and second color areas separated by a center line, acquiring an image of a real space including the marker, detecting the marker area, and analyzing the detected marker area So as to calculate the position, size, elevation of the image pickup relative to the marker, and azimuth rotation angle and rolling rotation angle of the marker and, according to the results of calculation and the shape data of the virtual object, calculating a composite image where a virtual object is arranged in a real space by a position, dimensions, and angles indicated by the marker.

Abstract: A data communication system capable of supplying information most desired by the receiving side in accordance with the state of a channel, wherein the receiving side transmits setting information for information transmission to the transmitting side, and the transmitting side generates and transmits the content data according to the setting information from the receiving side, a receiving apparatus of such a data communication system, and a data communication method for the same. The receiving apparatus reproduces the picture and sound signals according to received picture packets and sound packets, displays the reproduced picture as well as the state of the channel and the operational commands for the setting information, receives operational commands from the user by event processing, changes the setting information accordingly, then transmits the changed setting information to the transmitting apparatus.

Abstract: A magnetic resonance imaging apparatus generates an MR signal from an object to be examined by applying a gradient field pulse generated by a gradient field coil and a high-frequency magnetic field pulse generated by a high-frequency coil onto the object in a static field generated by a static field magnet, and reconstructs an image on the basis of the MR signal. The gradient field coil is housed in a sealed vessel. A cable extending from an external power supply and connected to the gradient field coil has predetermined flexibility.
