论文摘要
本文提出，制造和测试了用于手持光声成像探针的低成本调节照明方案。与传统的光声探针设计相比，它具有以下优点：（1）可以根据需要选择不同的激发模式。通过调整控制参数，它可以实现明亮场，深色场和混合场光照明方案。 （2）专为梁膨胀而设计的可调节单元（SAU），以及用于传输超声波的水箱，使设备能够突破转移介质的约束，并更广泛地使用。进行梁膨胀实验以验证SAU的功能。之后，我们根据新设计的设备构建了PAT系统。幻影和体内实验结果在不同的照明方案中显示出不同的性能
A low-cost adjustable illumination scheme for hand-held photoacoustic imaging probe is presented, manufactured and tested in this paper. Compared with traditional photoacoustic probe design, it has the following advantages: (1) Different excitation modes can be selected as needed. By tuning control parameters, it can achieve bright-field, dark-field, and hybrid field light illumination schemes. (2) The spot-adjustable unit (SAU) specifically designed for beam expansion, together with a water tank for transmitting ultrasonic waves, enable the device to break through the constraints of the transfer medium and is more widely used. The beam-expansion experiment is conducted to verify the function of SAU. After that, we built a PAT system based on our newly designed apparatus. Phantom and in vivo experimental results show different performance in different illumination schemes
