Abstract

To eliminate the limited angle effect of photoacoustic imaging based on ultrasound linear array, spatially distributed ultrasound sensor array is applied. The accurate sensor array position determines the quality of the imaging results. We proposed two methods based on photoacoustic and ultrasound signals to enhance the imaging quality using a full-ring array. Photoacoustic signals are used to regress the position of each element sensor. In phantom study and mouse brain study, imaging results can yield details clearly with average error rate of less than 50 μm. The proposed methods can contribute to precise biomedical imaging in future application scenarios.
