MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202531130373 A) filed by Vidyasagar University; Dr. Ksirhnendu Barman; and Dr. Priyanka Halder Mallick, Midnapore, West Bengal, on Dec. 22, 2025, for 'ultrasound-based hemodynamics: apparatus for measurement of blood flow dynamics and vascular function.'
Inventor(s) include Dr. Ksirhnendu Barman; and Dr. Priyanka Halder Mallick.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The invention discloses an ultrasound-based apparatus for comprehensive, real-time measurement of blood flow dynamics and vascular function. The portable device integrates a multi-element transducer with advanced beamforming for simultaneous B-mode imaging, vector Doppler, and tissue Doppler acquisition. Proprietary algorithms automatically detect vessel boundaries, compute angle-independent velocity vectors, fit flow profiles, track arterial wall motion, and derive key hemodynamic parameters including wall shear stress, arterial compliance, pulse wave velocity, flow-mediated dilation, pulsatility, and resistive indices. The system provides operator-independent results with high temporal resolution and accuracy, displayed on an intuitive interface with exportable reports. Designed for point-of-care use in superficial and deep vessels, it supports battery operation and wireless connectivity. Superior to conventional Doppler systems, it eliminates manual angle correction, enables full-lumen velocity profiling, and integrates multiple vascular function tests into one examination. This innovation facilitates early diagnosis of endothelial dysfunction, atherosclerosis, hypertension, and venous disorders, enhancing clinical outcomes in cardiovascular and vascular medicine through rapid, quantitative, non-invasive assessment unavailable in prior single-modality ultrasound devices."
