Claims (3)
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.
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.
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.
