This abstract first appeared for US patent application 20240032810 titled 'DEVICE, METHOD AND SYSTEMS FOR PROVIDING IMAGING OF ONE OR MORE ASPECTS OF BLOOD PERFUSION

==Simplified Explanation==

The present invention is a device, systems, and a method for providing imaging of blood perfusion in a skin region of a subject. Current perfusion imaging systems use either photoplethysmography (PPG) or speckle contrast (SC), but both techniques suffer from ambiguity in determining the source of the signal. 

The present invention combines widefield imaging and radial imaging to estimate the source depth of the signal, providing more accurate PPG and SC imaging. 

* Widefield imaging and radial imaging are combined to estimate the source depth of the signal.
* This allows for more accurate imaging of blood perfusion induced by cardiac-induced blood motion in a skin region.
* The invention addresses the ambiguity in determining the source of the signal in current perfusion imaging systems.
* By providing more accurate PPG and SC imaging, the invention improves the understanding of blood perfusion in a subject.

Potential applications of this technology:

* Medical diagnostics: The accurate imaging of blood perfusion can aid in the diagnosis and monitoring of various medical conditions, such as cardiovascular diseases and skin disorders.
* Research: The invention can be used in research studies to investigate the relationship between blood perfusion and various physiological and pathological processes.
* Sports performance monitoring: The technology can be applied in sports medicine to assess blood perfusion during physical activities and optimize training programs.

Problems solved by this technology:

* Ambiguity in current perfusion imaging techniques: The invention addresses the problem of uncertainty in determining the source of the signal in photoplethysmography and speckle contrast imaging.
* Lack of accuracy in perfusion imaging: By combining widefield and radial imaging, the invention provides more accurate estimation of the source depth of the signal, improving the accuracy of perfusion imaging.

Benefits of this technology:

* Improved understanding of blood perfusion: The invention allows for more accurate imaging of blood perfusion, leading to a better understanding of its dynamics and potential implications in various health conditions.
* Enhanced diagnostic capabilities: Accurate perfusion imaging can aid in the diagnosis and monitoring of medical conditions, enabling timely interventions and personalized treatment plans.
* Potential for advancements in research: The technology opens up new possibilities for studying blood perfusion and its relationship with physiological and pathological processes, contributing to advancements in medical research.


==Original Abstract Submitted==

the present invention relates to a device (), systems (″) and a method for providing imaging of one or more aspects of blood perfusion induced by cardiac induced blood motion in a skin region () of a subject. current perfusion imaging systems use either photoplethysmography (ppg) or speckle contrast (sc), but a problem of both techniques is that considerable ambiguity exists because the source of the signal (volume pulsatility in ppg or blood flow in sc) is unknown. the present invention is based on the idea of combining two different types of measurement, namely widefield imaging and radial imaging, in order to estimate the source depth () of the signal to provide more accurate ppg imaging and sc imaging.
