Study for backward scattering photoelectrical and smoke detector based on collimated beam
基於平行光束的後向散射光電感煙探測器的研究 -
The object of single photon emission computed tomography ( spect ) is to reconstruct an unknown radioactivity distribution inside the body from projection data consisting of the number of photon collected on a collimated gamma camera. these projections are not simple line integrals but have point - spreads due to the imperfect collimator of the detector and attenuation due to the compton scattering. so
這種投影數據與透射ct中的數據不同，由於存在著光子的點擴散（由準直器引起）和衰減（由散射引起） ，已經不能用簡單的線積分來描述這個問題，因此相對于透射ct而言，這個領域將面臨很多困難。
