Details
 

This fully tissue-equivalent anthropomorphic striatal phantom is designed for evaluation of quantitative striatal imaging in humans using SPECT, PET or MRI. The phantom can be filled with radioactive or MRI-signal-producing solutions. Ligands labeled with C-11, F-18 or I-123 are routinely used for evaluation of human neurodegenerative diseases such as Parkinson's disease.

Features and Benefits

  • The Head
    • The Head Phantom is based upon a standard RSD head with a calvarial cut to insert or remove the brain shell easily.
    • The nasal cavity and maxillary sinuses are filled with foam with a mass density of 0.23 g/cc.
  • Brain Shell
    • The brain shell has five compartments which can be filled separately: left and right nucleus caudate, left and right putamen, and the remainder of the brain.
    • This allows different nucleus caudate to putamen ratios as well as different striatal to background ratios to be obtained
    • This also permits differences between left and right striatal activity to be examined.
    • The volume of the brain shell is about 1,260 ml.
    • The volumes of the nucleus caudate and putamen are 5.4 ml and 6.0 ml respectively.
  • Fillable External Markers
    • A set of fillable capsules is provided to serve as external markers. Capsules can be filled with a radioactive solution and attached to the external surface of the phantom.
    • The phantom can then be imaged, using SPECT or PET modalities to compare image-registration techniques.
  • Quantification of striatal uptake is not straightforward because it depends on a number of factors:
    • Type of radionuclide used (Tc-99m, I-123 or F-18)
    • Imaging factors such as: collimator type, amount of scatter and attenuation
    • Image processing parameters such as: scatter and attenuation-correction techniques, type of reconstruction filter, slice thickness, region-of-interest size and its location
  • The putamen and head of the nucleus caudate are small structures with typical dimensions of 7-15 mm in the axial plane (that is comparable to the system resolution)

Warranty Information
