Abstract
The present disclosure discloses anatomical phantoms having one or more distinct regions spectroscopically differentiated from each other by inclusion of spectroscopically active components each having a distinct fluorescence/emission/scattering spectrum. The distinct regions may represent different anatomical components of the corresponding real anatomical part and/or tumor mimics (or other diseased tissue) and different anatomical components of the corresponding real anatomical part, or just tumor mimics and a remainder of the anatomical part. The spectroscopically active materials may be dyes such as the cyanine dyes, or spectroscopically active nanoparticles.
Claims22
A training phantom, comprising:
- a tissue mimic material formed into a volume of selected shape and size, the tissue mimic material being selected to mimic any one or combination of biomechanical and imaging properties of a given anatomical part;
- and
- at least one sub-volume of the volume of the tissue mimic material having located therein a spectroscopically active component which, when optically excited, responsively emits a distinct spectroscopic signature indicative of the sub-volume having a composition different to the rest of the volume.
A method of producing a training phantom, comprising the steps of:
- providing a mold of size and shape and volume of a given anatomical part for which the training phantom is being produced;
- providing a volume of liquid precursor of a tissue mimic material, the volume being substantially the same as the volume of the given anatomical part, and mixing at least one sub-volume of said volume of liquid precursor with a spectroscopically active component which, when optically excited, responsively emits a distinct spectroscopic signature indicative of the sub-volume having a composition different to the rest of the volume;
- curing the at least one sub-volume of liquid precursor containing the spectroscopically active component;
- and
- supporting the at least one sub-volume in a given location in the mold, and filling the mold with a remainder of the volume and curing the remainder of the volume to produce a phantom having at least one sub-volume having a spectroscopically active component mixed therein.
