Description
影されたサイノグラムは、第1または第2のサイノグラムの範囲の外にどんなデータが存在するのかを判断するために、第1または第2のサイノグラムと比較される。増強したサイノグラムを入手するために、この追加のデータは融合したサイノグラムと比較したサイノグラムに追加される。増強したサイノグラムは、融合整合再投影画像と呼ばれる画像に変換される。
子放射形断層撮影法のような異なる投影画像診断療法からの画像を整合するために一般的に使用することができる。それ故、データ収集方法が異なるために、2つの画像の間に整合のズレまたは不一致が起こる場合がある。
リングのようなMI技術のためにボクセルの数を低減する他の方法と比較すると、結果はより正確になる。
