摘要：<P>PROBLEM TO BE SOLVED: To acquire 3D images for a long time being free from the effects of the respiratory and cardiac cycles in medical imaging such as X-ray, tomodensitometry, magnetic resonance, etc. <P>SOLUTION: In order to prolong the duration of an examination by a scanner, the examination is carried out in two phases. A first dynamic phase (101) during which the patient holds his breath and the scanner explores a region Rdyn, and a second delayed phase (102) during which the patient breathes freely and the scanner explores the region Rdel. The latter includes the region Rdyn. The images acquired during the delayed phase are registered (103-107, 109-113) with relation to at least one dynamic phase image. This registration allows an image sequence covering a long time period for region Rdyn to be obtained. This registration permits being free from the effects of the respiratory and cardiac cycles. <P>COPYRIGHT: (C)2005,JPO&NCIPI
