Abstract
A head model according to one example of an embodiment is a head model that may be provided for use in the calibration for a brain-imaging device, where a part corresponding to the skull and a part corresponding to at least one specific region of the brain are each formed by a continuous cavity with no cuts other than an opening for liquid injection.
Claims13
A head model that may be provided for use in verification for brain imaging, where
- a part corresponding to the skull and a part corresponding to at least one specific region of the brain are each formed by a continuous cavity with no cuts other than an opening for liquid injection, and at least part of the structure surrounding said cavity is composed of a material having a linear absorption coefficient equivalent to that of human soft tissue.
A head model that may be provided for use in verification for brain imaging, comprising:
- a first-part for containing liquid that is provided on a part corresponding to the skull, and has a hollow structure with no discontinuous parts other than an opening for liquid injection;
- a second-part for containing liquid that is provided on a part corresponding to a specific region of the brain, and has a continuous hollow structure with no cuts other than an opening for liquid injection;
- and
- a structure that is formed as a single body so that said first and second-part for containing liquids are present therein, the structure formed by a material having a linear absorption coefficient equivalent to that of human soft tissue.
A method for producing a head model that may be provided for use in verification for brain imaging, where:
- forming three-dimensional CAD data, based on a morphological image of a human head, that represent at least each of the skull and a specific region of the brain as a hollow structure with no discontinuous parts other than an opening for liquid injection, and
- hardening a photo-curable resin through stereolithography based on the formed three-dimensional CAD data.
