Summary:PROBLEM TO BE SOLVED: To describe a method for determining a brain shift, such as the brain shift that occurs following a neurosurgical intervention.SOLUTION: The method comprises taking a first image of the brain (4) of a subject, the first image showing the position of blood vessels (20) in the brain relative to a reference position (30). A second image of the brain (4) that has been acquired following an intervention on the subject is also taken. This second image has been acquired using a computed tomography (CT) imaging apparatus. The second image shows the position of blood vessels (20') in the brain relative to the reference position (30). Brain shift is then determined from the shift in position of the blood vessels in at least one region of interest (32) of the brain, with respect to the reference position (30), between the first and second images. A corresponding apparatus is also described.SELECTED DRAWING: Figure 4 【課題】脳外科手術の介入に続いて起きる脳偏位など、脳偏位を決定するための方法が述べられる。【解決手段】方法は、被術者の脳(4)の第1の画像を取り込むステップを含み、第1の画像は、基準位置(30)に対する、脳中の血管の位置(20)を示す。また、被術者に対する介入に続いて取得される脳(4)の第2の画像が、取り込まれる。この第2の画像は、コンピュータ制御断層撮影法(CT)撮像装置を使用して取得されている。第2の画像は、基準位置(30)に対する、脳中の血管の位置(20')を示す。次いで、脳偏位は、第1の画像と第2の画像の間で基準位置(30)に対する、脳の少なくとも1つの対象領域(32)中の血管の位置の偏位から決定される。対応する装置も述べられる。【選択図】図4
