Abstract: A magnetic resonance imaging apparatus sound-proofing tube according to an embodiment is a sound-proofing tube for a magnetic resonance imaging apparatus and is formed by using a composite material including a fiber material and a resin material. In the magnetic resonance imaging apparatus sound-proofing tube, the fiber material forms a woven structure by being woven therein. The woven structure is formed so as to continuously extend over at least one round of the lateral face of the sound-proofing tube.

Abstract: A radiation detector according to an embodiment includes a scintillator array, a sensor array, electronic circuitry, a switch, and control circuitry. The scintillator array includes a plurality of scintillator pixels each configured to convert radiation into light. The sensor array includes a plurality of detection elements each configured to detect the light. The electronic circuitry is configured to output digital data on the basis of signals output from the detection elements. The switch is provided between the sensor array and the electronic circuitry. The control circuitry is configured to control the switch on the basis of a positional relation between the sensor array and the scintillator array.

Abstract: A vendor search assistance apparatus according to an embodiment includes: a memory that stores vendor information on each of plural vendors that have been registered; and processing circuitry configured to identify, on the basis of specification information of a proposition that has been advertised and the vendor information, recommended specification information that is recommended for the proposition, and notify a procurer that has advertised the proposition, of the recommended specification information.

Abstract: According to an embodiment, a radiation detector includes scintillator elements, dielectric multilayer films, and a metal reflective layer. The scintillator elements are arranged in a two-dimensional grid pattern. The dielectric multilayer films are provided between adjacent scintillator elements such that a dielectric multilayer film is adjacent to one of said scintillator elements. The metal reflective layer is provided between adjacent dielectric multilayer films.

Abstract: In order to accurately measure a shape feature of a minute droplet arranged on a substrate by a simple method, with respect to the droplet, the substrate is perpendicularly irradiated with laser light to cause diffracted light fluxes generated during passage of the laser light through the droplet to interfere with each other, so that a diffraction pattern is obtained. The diffraction pattern formed on a screen of a detector as an image is picked up by an image pickup apparatus. The shape feature of the droplet is measured by using the resultant diffraction pattern and a refractive index of the droplet.
