摘要： A radiation detection element includes a base material, a first electrode, a second electrode, a third electrode, a fourth electrode, a fifth electrode, a first external terminal, a second external terminal, a third external terminal, and a fourth external terminal. Each of the first external terminal, the second external terminal, the third external terminal, and the fourth external terminal is a solder ball, and the first external terminal, the second external terminal, the third external terminal, and the fourth external terminal are insulated from each other. A region provided on the first electrode, the second electrode, the third electrode, the fourth electrode, and the fifth electrode overlaps at least one of the first external terminal, the second external terminal, the third external terminal, and the fourth external terminal in a view vertical to the first surface side of the base material.

摘要： A radiation detection element includes a plurality of pixel electrodes, each pixel electrodes including a first electrode placed on the first surface of an insulating member and having an opening portion and a second electrode placed at the opening portion of the first electrode. The plurality of pixel electrodes is arrayed in the row direction and the column direction. The pitch of the pixel electrodes in the row direction and the column direction is 380 μm or less. An area ratio between the first electrode and the second electrode falls within the range of 14.5:1 to 154.6:1.

摘要： A gamma-ray image acquisition device (1) acquires the direction and energy of a target scattered gamma-ray generated by Compton scattering of an incident gamma-ray and acquires the direction and energy of a recoil electron. These pieces of information are used to acquire the incident direction and energy of the incident gamma-ray. The gamma-ray image acquisition device (1) acquires a two-dimensional image by imaging spectroscopy based on the incident directions and energies of a plurality of incident gamma-rays, the two-dimensional image being an image in which each pixel corresponding to each incident direction includes energy distribution information. In the two-dimensional image, the area and the solid angle of an imaging range are proportional to each other. This enables acquiring the distribution of gamma-ray intensities without depending on distance and thereby acquiring an image that indicates more useful information than conventional images.
