Recently, C-arm cone-beam CT systems have been used to acquire knee joints under weight-bearing conditions. For this purpose, the C-arm acquires images on a horizontal trajectory around the standing patient, who shows involuntary motion. The current state-of-the-art reconstruction approach estimates motion based on fiducial markers attached to the knee. A drawback is that this method requires calibration...
Non-recurrent intra-scan motion, such as respiration, corrupts rotational coronary angiography acquisitions and inhibits uncompensated 3D reconstruction. Therefore, state-of-the-art algorithms that rely on 3D/2D registration of initial reconstructions to the projection data are unfavorable as prior models of sufficient quality cannot be obtained. To overcome this limitation, we propose a compensation...
3D Stacked Image sensor is the stacking of a Back-Side Illuminated (BSI) CMOS Image Sensor on a logic die. It enables compact size, higher performances and additional functionalities compared to standard BSI sensors. The highest footprint reduction is obtained with 3D hybrid bonding with metal interconnects between top and bottom tiers. Hybrid bonding process with oxide / copper direct bonding allows...
