  • Patent number: 11933869
    Abstract: A method for magnetic resonance imaging (MRI) comprises applying a consecutive series of MRI sequences to a target volume (V) according to experimental settings (TR, ?, ?). A discrete sequence of transient response signals (Sn, Sn+1, Sn+2) is measured and fitted to a fit function (F) that is continuously dependent on a sequence number (n) of the respective MRI sequence (Pn) and corresponding response signal (Sn). A shape of the fit function is determined according to an analytically modelled evolution by the experimental parameters (TR, ?, ?) as well as variable intrinsic parameters (r, ?3, ?, ?) to be fitted. For example, the model is based on an equivalent harmonic oscillator. The intrinsic parameters of the fit function can be related to the intrinsic properties (PD, T1, T2) of the spin systems and used for imaging the target volume (V). Various optimizations of contrast can be achieved by tuning the experimental settings according to the model.

  • Publication number: 20220090007
    Abstract: According to one method, a sample with cells contains a phototagging agent. The sample is imaged to identify at least one target cell to be isolated. The identified target cell in the sample is selectively irradiated with photo-activating light for selectively activating the phototagging agent in the target cell to change its fluorescence response. The irradiated target cell is isolated from other cells in the sample based on a difference in its fluorescence response compared to non-activated phototagging agent in the other cells. Further aspects are directed to a corresponding microscope system and chemical compound for use as the phototagging agent.
