  • Publication number: 20150285972
    Abstract: The present invention relates to a heat-ray-shielding sheet that includes, on a support, a heat-ray-shielding layer including heat-shielding microparticles and a resin binder filling a void part. The microparticles are made of tin-doped indium oxide (ITO) or the like and have an average particle diameter of equal to or less than 100 nm, the reflectance in the heat-ray-shielding layer at a wavelength of at least 2,000 nm is at least 15%, and the surface resistivity in the heat-ray-shielding layer is equal to or more than 106?/?. Increasing the surface resistivity imparts a radio-wave-transmitting property, and causing longer-wavelength near-infrared light to be reflected boosts heat-ray-shielding efficiency while preventing thermal cracking and the like of a glass substrate. Additionally compounding the heat-ray-shielding layer with a near-infrared-absorbing dye, or disposing a reflecting layer in addition to the heat-ray-shielding layer allows the heat-ray shielding effect to be further improved.

A dedicated device for obtaining the heartbeat or breathing beat such as ECG and a respiratory measuring device is not required, and a heartbeat signal and a breathing beat signal can be obtained from an ROI signal of the projection data. As a result, blurring on an image caused by the heartbeat can be eliminated, and an image quality is extremely improved.
