Patent number: 11906425Abstract: A phantom design method includes a correction step and a calculation step. In the correction step, an absorption spectrum of a target of spectroscopic measurement by a near infrared spectrometer is corrected based on a refractive index of the target and a refractive index of a resin used as a base material of a phantom to generate a corrected absorption spectrum. In the calculation step, based on an absorption spectrum of the resin and an absorption spectrum of each of N types of dyes, a concentration of each of the N types of dyes to be contained in the base material is calculated such that an absorption spectrum of the phantom constituted by the base material containing the N types of dyes approximates the corrected absorption spectrum in a predetermined wavelength range of a near infrared region.Type: GrantFiled: June 1, 2020Date of Patent: February 20, 2024Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Kenji Yoshimoto, Yukio Ueda
