Radiation detection device, recording medium, and positioning method

A non-transitory recording medium recording a computer program that causes a computer to control a radiation detection device including an optical microscope configured to observe a sample, an irradiation unit that irradiates the sample observed by the optical microscope with radiation, and a detection unit that detects radiation generated from the sample irradiated with the radiation,

• wherein the computer program causes the computer to perform a process including:
• a step of adjusting a relationship between a focal position of the optical microscope and a position of the sample such that the optical microscope is focused on one portion of the sample;
• a step of changing a position, on which the optical microscope is to be focused, on the sample;
• a step of calculating a distance from a predetermined base point to the surface of the sample at the changed position on the sample according to the adjusted focal position;
• a step of creating a partial image captured by the optical microscope at the changed position on the sample in a state in which adjustment of the relationship is performed for focusing;
• and
• a step of creating a sample image including information in which the calculated distance is associated with each of a plurality of portions of the sample by combining a plurality of created partial images.

A method for positioning a portion to be irradiated with radiation in a sample using a radiation detection device including an optical microscope configured to observe a sample, an irradiation unit that irradiates the sample observed by the optical microscope with the radiation, and a detection unit that detects radiation generated from the sample irradiated with the radiation, the method comprising:

• adjusting a relationship between a focal position of the optical microscope and a position of the sample such that the optical microscope is focused on one portion of the sample;
• sequentially changing a position, on which the optical microscope is to be focused, on the sample;
• calculating a distance from a predetermined base point to the surface of the sample at the changed position on the sample according to the adjusted focal position;
• creating a partial image captured by the optical microscope at the changed position on the sample in a state in which adjustment of the relationship is performed for focusing;
• creating a sample image including information in which the calculated distance is associated with each of a plurality of portions of the sample by combining a plurality of created partial images;
• and
• positioning the portion to be irradiated with the radiation in the sample, on the basis of the sample image.
