All

Inclusion criteria

Inclusion criteria: 1.Patients aged 12 years to 85 years at the time of consent acquisition and suspected to have vascular disease, who are judged by their doctor that in a condition without any problems participating in the research. 2.Persons in accordance with criteria 1 who have agreed to participate in this study from their own free will with document consents.

Exclusion criteria

Exclusion criteria: 1. Pregnancy or possible pregnancy. 2.The status of immunodeficiency due to neutropenia and so on. 3.Complications that make imaging difficult (e.g. inability to maintain the posture). 4.In cases where it is judged by the research director or the attending physician that it is inappropriate for carrying out this research (e.g. having trouble with the subject's physical condition by keeping the posture during the imaging).

Design outcomes

Safety

Secondary

MeasureTime frame
The capability of the photoacoustic imaging system for visualizing the vascular lesion of the patients (The blood vessel, inner diameter, and three-dimensional running directions of the blood vessels are evaluated in three phases of evaluations which are inability to depict, incomplete depiction, and good depiction.)
