In the body of the text, the following citations were corrected:
• from 12 to 13, for the sentence
• from 13 to 14, for the sentences
▪ “PARS replaces the acoustically coupled ultrasound transducer with a detection laser.”
▪ “Photoacoustic signals are then detected as pressure-induced modulations in the backscattered magnitude of the detection beam.”
▪ “Observing backscattering in a reflection mode architecture allows PARS to image thick samples.”
• from 14 and 15, to 15-18, for the sentence
• from 19 and 20, to 17 and 18, for the sentences
▪ “Previously, PARS has provided complete H&E emulation using a tunable excitation source to independently target the absorption peaks of DNA and cell membrane structures.”
▪ “While effective in both thin sections and tissue blocks, this technique was largely limited in field of view, resolution, and imaging speed since it required the use of a slow (1 kHz) tunable excitation source.”
• from 13 to 14, for the sentences
▪ “In PARS systems, a cofocused pulsed excitation and continuous wave detection laser pair are used to capture photoacoustic absorption contrast.”
▪ “The excitation induces photoacoustic signals by depositing focused pulses of optical energy into the sample.”
▪ “The absorption contrast is then captured as nanosecond scale pressure-induced modulations in the backscattered intensity of the cofocused detection laser.”
▪ “Usually, to capture MHz-scale PARS modulations, the time-resolved backscattering magnitude is band pass filtered to isolate the absorption signal.”
• from 16 and 17, to 17 and 18 for the sentences
▪ “Previous implementations developed by our group leverage a multiwavelength tunable excitation to capture hyperspectral images of several chromophores in the tissue.”
▪ “In this implementation, we use a 50-kHz UVexcitation, which provides emulated H&E images substantially faster than the 1-kHz tunable source used in previous studies.”
The above-listed errors were corrected, and the article was republished on 26 May 2021.
