Simulation of Capillary Hemodynamics and Comparison with Experimental Results of Microphantom Perfusion Weighted Imaging [PDF]
Journal of Biomedical Physics and Engineering, 2020 Background: Perfusion imaging, one of MRI’s techniques, is widely used to test damaged tissues of the body. The parameters used in this technique include cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT). The MRI scanner

Image of a regular phantom compact object and its luminosity under spherical accretions [PDF]
Class.Quantum Grav. 38, 115008 (2021), 2020 We have studied the shadow and its luminosity for a static and regular phantom compact object under the static spherical accretion and the infalling spherical accretion, respectively. Comparing with the usual Schwarzschild black hole, the presence of phantom hair yields the larger black hole shadow and the darker image.
