Description
ジタルデータの作成において次第に普及している。幾つかの既知のデジタルX線イメージングシステムにおいて、線源からの放射線は、医学的診断用途で患者などの被検体に向かって配向される。放射線の一部は患者を透過して検出器に衝突し、そこで検出器が放射線を光フォトンに変換して該光フォトンが感知される。検出器は離散的画素、すなわちピクセルのマトリクスに分割され、各ピクセル領域に衝突する放射線の質又は強度に基いて出力信号をコード化する。放射線強度は放射線が患者を透過すると変化するので、出力信号に基づいて再構築された画像は、従来のX線用感光性フィルム技術により利用可能な画像像と同様の患者の組織投影を提供する。
