An information processing apparatus generates heart shape data indicating a three-dimensional shape including an internal structure of a heart of a subject based on echo image data indicating a cross-sectional image of the heart. The information processing apparatus then generates thorax shape data indicating a three-dimensional shape of a thorax of the subject based on X-ray image data indicating an X-ray image of the thorax of the subject. The information processing apparatus then decides, based on an image of the heart appearing in the X-ray image, a position and an orientation of the three-dimensional shape of the heart indicated by the heart shape data within the three-dimensional shape of the thorax indicated by the thorax shape data.

A superconducting cavity has a long time constant when the coupling factor of its output port is low so as to accumulate input microwave energy therein, and after a certain accumulation of the input microwave, an output microwave pulse with a large power is extracted from the cavity by suddenly increasing the coupling factor of its output port.

A magnetron injection gun comprising a conical cold-cathode and a cylindrical anode coaxially surrounding the cold-cathode. The anode is provided with an annular projection extending toward the emission ring surface, and the surface of the conical cold-cathode is coated with an insulating film, except for a portion opposite the end of the annular projection, which forms a conductive emission ring.
