Abstract: An optical fingerprint recognition circuit and a display device are provided, which includes a first thin film transistor, a first switching unit, a second switching unit, a reset compensation unit, a storage capacitor, and a photodiode. The reset compensation unit resets a voltage of the gate of the first thin film transistor under the control of a reset signal, and the voltage is set to a sum of a predetermined voltage and a threshold voltage of the first thin film transistor through a reference voltage under the control of the reset signal, thereby compensating the threshold voltage.

The accuracy of a recognition signal is ensured.

Abstract: Some aspects of the present disclosure relate to systems and methods for magnetic resonance thermometry. In one embodiment, a preliminary balanced steady state free precession (bSSFP) magnetic resonance imaging pulse sequence is applied to an area of interest of a subject.
