The present invention provides a method of detecting microbubbles in a vessel of an affected part, comprising aggregates the microbubbles, acquiring phase-contrast magnetic resonance images and analyzing the phase-contrast magnetic resonance images. Thus, we can detect or monitor the size and location of the microbubbles in vessels of any part of body.

Method of detecting microbubbles in a vessel

A processing device performs dual-rail power equalization for its memory cell array and logic circuitry. The memory cell array is coupled to a first power rail through a first switch to receive a first voltage level. The logic circuitry is coupled to a second power rail through a second switch to receive a second voltage level that is different from the first voltage level. The processing device also includes a power switch coupled to at least the second power rail and operative to be enabled to equalize voltage supplied to the memory cell array and the logic circuitry.

A bulk-driven current-sense amplifier and an amplifier operating method are disclosed. The bulk-driven current-sense amplifier includes a differential amplifier, a first driver, and a second driver. The first driver is coupled to the differential amplifier, and a first node is formed at a connectivity segment of the first driver. The second drive is coupled to the differential amplifier, and a second node is formed at a connectivity segment of the second driver. When a first switch of the first driver and a second switch of the second driver are turned on, the differential amplifier charges the first node and the second node. When the charging is completed, the first node and the second node respectively have a different stabilized potential according to currents separately flowing through a first memory unit of the first driver and a second memory unit of the second drive, and the differential amplifier generates a voltage.
