Figure Lengend Snippet: (a) Schematic illustration of circular scanning geometry. (b) Simulation geometry used in MATLAB k-wave toolbox. UST: ultrasound transducer. (c) Point source numerical phantom. (d) Vessel source numerical phantom. (e) Brain source numerical phantom. (f-h) One representative image for (c-e), respectively. (i) Schematic of the PACT imaging system. P1, P2, and P3 are prisms; L1: planoconcave lens; The rotating disc is connected to UST and controlled by a stepper motor. The UST and sample are immersed in a water bath for better acoustic coupling.
