被検体にX線を照射するX線源と、前記X線源に対向配置され前記被検体を透過したX線を検出するX線検出器と、前記X線源と前記X線検出器を搭載し前記被検体の周囲を回転するスキャナと、前記X線検出器で検出した透過X線量に基づき被検体の断層画像を再構成する画像再構成装置と、前記画像再構成装置で再構成した断層画像を表示する画像表示装置と、前記断層画像の輝度値に基づき各臓器を画像上で抽出する臓器抽出手段と、を備えたX線CT装置において、
前記抽出された臓器の中に基準点を設定し、前記基準点と前記基準点の周囲の画素の輝度値に基づき、前記基準点が設定された臓器に接続している接続血管を特定する接続血管特定手段をさらに備えることを特徴とするX線CT装置。
Equipped with an X-ray source that irradiates a subject with X-rays, an X-ray detector that is disposed opposite to the X-ray source and detects X-rays transmitted through the subject, and the X-ray source and the X-ray detector A scanner that rotates around the subject, an image reconstruction device that reconstructs a tomographic image of the subject based on a transmitted X-ray amount detected by the X-ray detector, and a tomogram that is reconstructed by the image reconstruction device An X-ray CT apparatus comprising: an image display device that displays an image; and an organ extraction unit that extracts each organ on the image based on a luminance value of the tomographic image.
A connection that sets a reference point in the extracted organ and identifies a connected blood vessel connected to the organ in which the reference point is set based on luminance values of the reference point and pixels around the reference point An X-ray CT apparatus further comprising blood vessel specifying means.
請求項1に記載のX線CT装置において、The X-ray CT apparatus according to claim 1,
前記接続血管特定手段は、血管が太くなる方向または分岐角度の大きい方向に接続血管を特定することを特徴とするX線CT装置。The X-ray CT apparatus characterized in that the connected blood vessel specifying means specifies a connected blood vessel in a direction in which the blood vessel becomes thicker or in a direction with a larger branch angle.
請求項1または2に記載のX線CT装置において、The X-ray CT apparatus according to claim 1 or 2,
前記基準点が設定された臓器と前記接続血管の接続状態に応じて、不適当な術式を警告する術式警告手段をさらに備えることを特徴とするX線CT装置。An X-ray CT apparatus further comprising a technique warning means for warning an inappropriate technique according to a connection state between the organ in which the reference point is set and the connection blood vessel.
