The goal of this observational study is to learn whether noninvasive real-time arterial waveform monitoring can be used to assess cardiovascular diseases in adults. The main question it aims to answer is: Can photoacoustic imaging accurately capture arterial waveforms from patients' fingers? Can features extracted from the arterial waveforms reflect the type and severity of cardiovascular diseases? Participants will be asked to place their fingers into the imaging device, where their finger arterial pulse information will be noninvasively recorded.
