Title:
Ultrawideband reflection-mode optoacoustic mesoscopy. 
Abstract:
We developed a reflection-mode optoacoustic mesoscopy system, based on raster-scanning of a custom designed spherically focused ultrasound detector, enabling seamless epi-illumination of the volume imaged. We study the performance of acoustic-resolution mesoscopy operating at an ultrawideband bandwidth of 20-180 MHz. i.e., a frequency band spreading over virtually an order of magnitude. Using tomographic reconstruction we showcase previously unreported, to our knowledge, axial resolutions of 4 ?...    »
