TROPUS imaging. (A) Lay-out of the imaging set-up combining three modalities, namely MSOT, RUCT and SoS imaging. Only half of the ring array is shown for better visualization. (B) Absorption spectrum of Hb, HbO2 and lipid in 700 nm and 1000 nm wavelength range. (C) Exemplary MSOT images from different cross sections recorded at 1064 nm excitation wavelength. (D) The corresponding cross sections reconstructed with the RUCT modality. (E) The corresponding cross sections showing the SoS maps reconstructed with TUCT modality. Hb: deoxy-hemoglobin; HbO2: oxy-hemoglobin, MSOT: multispectral optoacoustic tomography; RUCT: reflection ultrasound computed tomography; SoS: speed of sound; TROPUS: transmission-reflection optoacoustic ultrasound; TUCT: transmission ultrasound computed tomography.
