Zusammenfassung:To provide a panoramic X-ray imaging apparatus that can improve the resolution of a panoramic image.SOLUTION: A panoramic X-ray imaging apparatus includes: an X-ray generating unit; an X-ray detecting unit 44; a support that supports the X-ray generating unit and the X-ray detecting unit 44 so that the X-ray generating unit and the X-ray detecting unit 44 face each other; a drive mechanism that drives the support; a subject holding unit that holds an imaging subject M; and a turning control unit that controls the movement of the support by the drive mechanism so that the X-ray generating unit and the X-ray detecting unit 44 turn around a head P to perform panoramic X-ray imaging. The turning control unit can set panoramic turning orbits of X-ray detecting unit 44 for the same imaging subject M, which are a first turning orbit and a second turning orbit R2. The second turning orbit R2 is closer to the surface of the head P than the first turning orbit in front of and on the side of the head P.SELECTED DRAWING: Figure 10 【課題】パノラマ画像の解像度を向上させることが可能なパノラマX線撮影装置を提供することを目的とする。【解決手段】X線発生部と、X線検出部44と、X線発生部とX線検出部44とが対向するようにX線発生部とX線検出部44とを支持する支持部と、前記支持部を駆動する駆動機構と、撮影対象者Mを保持する被写体保持部と、X線発生部とX線検出部44とが頭部Pの周りを旋回してパノラマX線撮影を行うように、駆動機構による支持部の動作を制御する旋回制御部とを備え、旋回制御部が、同一の撮影対象者Mに対するX線検出部44のパノラマ旋回軌道として、第1旋回軌道と第2旋回軌道R2とを設定可能に構成され、第2旋回軌道R2は、頭部Pの前方及び側方において、第1旋回軌道よりも頭部Pの表面に近接した軌道とされている。【選択図】図10
