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。 -
Static electric field makes human body relax, eliminate tenseness, weaken liver ' s radioactivity to the brain, prevent unusual brain waves and brain magnet ' s appearance, strengthen cerebral cortex ' s scattered preventing function, make brain waves fall into circumstances of relaxing and slow a wave or wave during sleep
靜電場促使人體全身放鬆，消除人體緊張狀態，減少肝臟向大腦射電，消除異常腦電波和腦磁的發生，增強大腦皮層擴散型抑制功能，促使腦電波進入輕松緩慢的波和入睡時的波狀態。
