inSPira HD is a portable, single photon emission computed tomography (SPECT) camera constructed for brain imaging.

The SPECT camera is capable of imaging any radioisotope energies between 80-200 keV for clinical applications such as epilepsy, Parkinson’s disease, neuropsychology, stroke and brain perfusion as well as Alzheimer’s disease and dementia.

Montreal Neurological Institute PET unit director Jean-Paul Soucy said since inSPira HD has reconstructed spatial resolution to 3mm and true attenuation correction, it will give physicians more detailed clinical information of brain activity by allowing them to better evaluate cerebral blood flow distribution patterns.
