	Compressed sensing for MRI perfusion imaging Daňková, M. ; Rajmic, P. ; Jiřík, Radovan Perfusion MRI is a diagnostic method in medicine. The signal captured from the affected area can be described by the curve of lognormal distribution. The standard way of obtaining the measurements is very slow and does not comply with today's challenging requirements. Using compressed sensing, we propose to acquire much less coefficients, having minimal effect on the signal reconstruction (using the assumption that the data is a sum of low-rank matrix and sparse matrix in row spectrum).

	Software Package for Ultrasound Perfusion Imaging Mézl, M. ; Jiřík, Radovan In this work a Matlab-based software package for perfusion imaging is presented. It is run with a graphical user interface (GUI) and includes five main steps of perfusion analysis. There are applications for data import, image registration, tissue selection, perfusion analysis and visualization. This software has been used for analysis of abdominal ultrasound sequences. It is modular and each module can be easily modified for various methods as well as different image modalities for example magnetic resonance imaging. Detailed record
