Gamma ray detector characterized in that its structural elements are a continuous scintillator crystal, a position sensitive photodetector and associated electronics intended to calculate in addition to the gamma ray , energy in the position of its interaction in the crystal the interaction , depth in the crystal from the standard deviation of the scintillation light distribution. Said information may be obtained electronically in analog form , and therefore instantaneous from the first three moments of the scintillation light distribution. A method for implementing said electronics by way of a network of resistances characterized for analog and simultaneous computation of the first …

Why it's free to use
- Filed April 7, 2004 and granted October 16, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 7, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 7, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
