N2 - A number of optoacoustic (or photoacoustic) microscopy and mesoscopy techniques have successfully been employed for non-invasive tumor angiography. However, accurate rendering of tortuous and multidirectional neoplastic vessels is commonly hindered by the limited angular coverage of commercially available ultrasound transducers. In this work, it is theoretically and experimentally shown that a wide viewing angle allows obtaining more detailed and continuous images of the of the intricate arbitrarily-oriented neovasculature in experimental tumors. To reduce the effect of a limited field of view, a detector based on a PVDF piezopolymer film was developed, which has an ultra-high numerical aperture of 0.9,
