  1. We start this paper with the mathematical model of the spect problem. the ( direct ) process that a photon emitting from the source follows its path toward the camera is described in mathematical and physical languages

    本文從問題的數學模型開始,用數學和物理的語言詳細闡述了光子由放射源出發直至最終到達檢測器的整個過程,也即通常所說的正過程。
  2. 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。
