MoleculUS is a dual-modality ultrasound and photoacoustic data acquisition unit that allows the simultaneous collection of ultrasound and photoacoustic channels sharing the same probe elements. The analog signal path of MoleculUS is split into PA and US paths. PA and US modes operate sequentially in time with support for US preview mode and continuous on-fly multiplexing between modes. For PA mode data acquisition, each channel has a dedicated preamplifier with high input impedance and a fixed 40 dB gain. MoleculUS can use linear, convex, and endocavitary handheld probes. Software SDK and user interface are written in MATLAB® (compiled and source code versions); the back-end is a compiled C++ 64-bit DLL library.
