description To provide an X-ray diagnostic apparatus and an image processing method capable of generating a composite image on the basis of a nondestructively read-out signal before the end of X-ray irradiation and a destructively read-out signal after the end of X-ray irradiation.SOLUTION: An X-ray diagnostic apparatus includes an X-ray detection unit, a nondestructive read-out unit, a destructive read-out unit, and an image generation unit. The X-ray detection unit includes a plurality of X-ray detection elements. The nondestructive read-out unit nondestructively reads out signals accumulated in the X-ray detection element corresponding to one of a first region and a second region of X-ray imaging regions before the end of X-ray irradiation. The destructive read-out unit destructively reads out signals accumulated in the X-ray detection element corresponding to the other of the first region and the second region after the end of X-ray irradiation. The image generation unit generates a composite image that composites a first region image generated on the basis of the signals accumulated in the X-ray detection element corresponding to the first region and a second region image generated on the basis of the signals accumulated in the X-ray detection element corresponding to the second region.SELECTED DRAWING: Figure 1 【課題】X線ばく射終了前に非破壊読み出しした信号と、X線ばく射終了後に破壊読み出しした信号とにもとづいて合成画像を生成することができるX線診断装置および画像処理方法を提供する。【解決手段】実施形態に係るX線診断装置は、X線検出部と、非破壊読出部と、破壊読出部と、画像生成部とを備える。X線検出部は複数のX線検出素子を有する。非破壊読出部は、X線撮像領域のうち、第1領域と第2領域の一方の領域に対応するX線検出素子に蓄積された信号を、X線ばく射終了前に非破壊読み出しする。破壊読出部は、第1領域と第2領域の他方の領域に対応するX線検出素子に蓄積された信号を、X線ばく射終了後に破壊読み出しする。画像生成部は、第1領域に対応するX線検出素子に蓄積された信号にもとづいて生成した第1領域画像と、第2領域に対応するX線検出素子に蓄積された信号にもとづいて生成した第2領域画像と、を合成した合成画像を生成する。【選択図】 図1
