摘要:
In a multi-session imaging study, information from a previous imaging session is stored in a Binary Large Object (BLOB). Current emission imaging data are reconstructed into a non-attenuation corrected (NAC) current emission image. A spatial transform is generated aligning a previous NAC emission image from the BLOB to the current NAC emission image. A previous computed tomography (CT) image from the BLOB is warped using the spatial transform, and the current emission imaging data are reconstructed with attenuation correction using the warped CT image. Alternatively, low dose current emission imaging data and a current CT image are acquired, a spatial transform is generated aligning the previous CT image to the current CT image, a previous attenuation corrected (AC) emission image from the BLOB is warped using the spatial transform, and the current emission imaging data are reconstructed using the current CT image with the warped AC emission image as prior.
摘要(中):
在多会议成像研究中,来自先前成像会话的信息存储在二进制大对象(BLOB)中。 当前发射成像数据被重建为非衰减校正(NAC)电流发射图像。 生成空间变换,将来自BLOB的先前NAC发射图像与当前NAC发射图像对齐。 使用空间变换对来自BLOB的先前计算机断层摄影(CT)图像进行扭曲,并且使用扭曲的CT图像利用衰减校正来重建当前发射成像数据。 或者,获取低剂量电流发射成像数据和当前CT图像,生成将先前CT图像与当前CT图像对齐的空间变换,使用空间变换使来自BLOB的先前衰减校正(AC)发射图像变形 并且使用具有翘曲的AC发射图像的当前CT图像重建当前发射成像数据。 p>
