Paper Abstract

Clinical PA (photoacoustic) /US (ultrasound) imaging has been widely explored and in most cases is performed in 2D. However, 2D PA/US imaging technology has problems of low reproducibility and high operator dependency. For these reasons, we developed a clinical handheld 3D PA/US scanner using an 1D linear array US transducer and a compact mechanical scanner, which is managed by a Scotch yoke mechanism. The total weight, overall size and the field of view (FOV) of the scanner are 950 g, 100 × 80 × 100 mm3 and 38 × 40 mm2, respectively. We have successfully evaluated the feasibility of clinical use by acquiring various images of the human body parts such as face, neck and calf. We believe that the hand-held scanner can be used for a variety of clinical applications.
