Summary:To generate a highly accurate nuclear medicine image having a pixel size that is simply and accurately segmented without segmenting a detection element.SOLUTION: A nuclear medicine diagnostic apparatus includes a nuclear medicine detector, a relative position control section, a data collection section, and a reconstruction processing section. The nuclear medicine detector has a plurality of detection elements that detect gamma rays. The relative position control section controls a change from a first relative position of the nuclear medicine detector and a subject to a second relative position that is separate from the first relative position by a distance smaller than an element size of the detection element. The data collection section collects first data in the first relative position and collects second data in the second relative position. The reconstruction processing section reconstructs a nuclear medicine image on the basis of the first data and the second data.SELECTED DRAWING: Figure 6 【課題】検出素子を細分化することなく、簡便にかつ精度良く細分化されたピクセルサイズの高精度の核医学画像を生成すること。【解決手段】本実施形態に係る核医学診断装置は、核医学検出器と、相対位置制御部と、データ収集部と、再構成処理部と、を備える。核医学検出器は、ガンマ線を検出する複数の検出素子を有する。相対位置制御部は、前記核医学検出器と被検体との第1の相対位置から、前記検出素子の素子サイズよりも小さい距離だけ前記第1の相対位置から離れた第2の相対位置への変更を制御する。データ収集部は、前記第1の相対位置において第1のデータを収集し、前記第2の相対位置で第2のデータを収集する。再構成処理部は、前記第1のデータと前記第2のデータとに基づいて、核医学画像を再構成する。【選択図】図6
