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...
This paper presents a method based on fluorescence diffuse optical tomography for reconstructing the fluorescence yield of heterogeneous and arbitrary shaped medium such as small animals. The experimental set-up is presented and the associated reconstruction method making mouse inspection without immersion in optical index matching liquid (Intralipid and ink) possible is detailed. Some phantom experiments...
This paper presents a new fluorescence diffuse optical tomographic (fDOT) system and its associated reconstruction method. It is able to reconstruct the fluorescence yield even in heterogeneous and highly attenuating regions. Furthermore our reconstruction method makes mouse inspection without immersion in optical index matching liquid (Intralipid and ink) possible. Some phantom experiments have been...
A fluorescence enhanced diffuse optical tomography algorithm taking into account the optical heterogeneities is presented. It is suitable for continuous wave acquisitions and naturally handles complex shaped object. Therefore, it allows in vivo studies of small animals injected with target-specific fluorescent probes without immersion fluid. A comparison with previous methods conducted on simulations...
