The work considers a theranostic system that implements a multimodal approach allowing the simultaneous generation of singlet oxygen and visualization of the various parameters of the vascular bed. The system, together with the developed data processing algorithm, has the ability to assess architectural changes in the vascular network and its blood supply, as well as to identify periodic signal changes associated with mechanisms of blood flow oscillation of various natures. The use of this system seems promising in studying the effect of laser-induced singlet oxygen on the state of the vascular bed, as well as within the framework of the theranostic concept of treatment and diagnosis of oncological diseases and non-oncological vascular anomalies.
