Point spread functionRegistrationScattered data approximationMRCP studyMR image acquisition of moving organs remains challenging despite the advances in ultra-fast 2D MRI sequences. Post-acquisition techniques have been proposed to increase spatial resolution a posteriori by combining acquired orthogonal stacks...
Optimal Point Spread Function for 3D High-Precision Imaging We generate an information-optimal point spread function (PSF) for localization-based 3D imaging. Such a PSF exhibits excellent localization precision by design, as we demonstrate theoretically and experimentally, and can be tailored for... ...

In this work, we engineer a LanM-derived protein MRI contrast agent for high-resolution vascular imaging and effective monitoring of kidney dysfunction (Fig. 1a). Through sequence alignment and structural analysis, we introduce a single-point mutation into the fourth weak ion-binding site of LanM...
The evaluation is conduction on 19,816 3D BOLD MRI volumes acquired on a 3T Skyra scanner. The proposed method achieves an average detection accuracy of 87.3% under a 10-mm threshold and 6.9mm as the mean error. In Leroy et al. (2020), a communicative multi-agent reinforcement learning ...
mriedo commented Sep 26, 2020 • edited I agree with Stefan that these 3 functions ar very useful but don't know if it will already be in the first implementation more focused on visualisation. For the moment these 3 functionalities are available in cloudcompare and I use them on a dai...
The scaled form is employed for unscented transform, which requires a scaling term: λ = α2(N + β) − N (40) The α parameter is used to control the sigma points spread with respect to the mean of the state; we usually set a small positive value for parameter...
