Twente光声乳房检验仪(PAM)使用1064 nm的脉冲光来激发PA信号。检测使用平面590元件超声(US)传感器矩阵。图像重建使用延迟和波束形成算法。测量是在向前模式下进行的，使用US偶联凝胶对检测器进行轻微的乳房压缩。我们巩固了该系统最重要的规范。此外，我们还详细讨论了两例浸润性导管癌和一例囊性病变的影像结果。我们批判性地讨论了本实施例的特点，并提出了改进计划。
The Twente photoacoustic mammoscope (PAM) uses pulsed light at 1064 nm to excite PA signals. Detection is using a planar 590-element ultrasound (US) sensor matrix. Image reconstruction uses a delay-and-sum beamforming algorithm. Measurements are performed in the forward mode, with mild compression of the breast against the detector with US coupling gel. We consolidate the most important specifications of the system. Furthermore, we discuss in detail the results of imaging two cases of infiltrating ductal carcinoma and one case of a cyst. We critically discuss the features of the present embodiment and present plans for its improvement.
