我们建立了一个光声成像系统，使用强度调制的连续波激光源，这是一个廉价的，紧凑的，耐用的120 mW的激光二极管。目标是显著降低光声成像系统的成本和尺寸。通过使用一个碗状的压电换能器，其数值孔径为0.85，谐振频率为2.45 MHz，我们的图像生物组织的横向分辨率为0.45 mm，轴向分辨率为1 mm，信噪比高达43 dB。(C)2008年，由光学仪器工程师协会（Society of Photo-Optical Instrumentation Engineers）主办。
We build a photoacoustic imaging system using an intensity-modulated continuous-wave laser source, which is an inexpensive, compact, and durable 120-mW laser diode. The goal is to significantly reduce the costs and sizes of photoacoustic imaging systems. By using a bowl-shaped piezoelectric transducer, whose numerical aperture is 0.85 and resonance frequency is 2.45 MHz, we image biological tissues with a lateral resolution of 0.45 mm, an axial resolution of 1 mm, and an SNR as high as 43 dB.
