A system and method for providing continuous non-invasive measurements and calculations of the dynamically changing pressures inside a person's body, said system comprising of ultrasound or other medical imaging device connected to an end-user control unit presumably computer or a mobile device, said end-user control unit
- records an initial image stream {Ji}i=1, . . . N of cardiovascular movement of a said body from the said imaging device;
- processes the initial image stream {Ji}i=1, . . . N generating corresponding T-image {Ti}i=1, . . . N defined as a chronological union of said initial image stream {Ji}i=1, . . . N with corresponding time stamps;
- said control unit then processes the T-Image {Ti}i=1, . . . N to determine the oscillating traceable regions corresponding to cardiovascular features and records their form changing over time;
- said oscillating traceable region is defined as a region appearing on most images comprising the T-Image {Ti}i=1, . . . N and corresponding to the physiological domain where the pressure is measured or calculated;
- said form changing corresponds to relative changes in the pressure in the said oscillating traceable regions;
- said relative changes in pressure comprise an independent diagnostic tool;
- said continuous non-invasive measurements and calculations of the dynamically changing pressures inside a said person's body can be performed at any time or place by directing the said imaging device connected to the said end-user control unit to the region of interest, such as the heart or heart chambers and performing a recording from which the said control unit will produce a calculated relative real-time pressure value series {P(ti)}i=1, . . . N;
- said end-user control unit is able to obtain the absolute pressure values as a function corresponding to the said form changing of the said oscillating traceable region;
- said function is obtained during either patient personal calibration procedure or using a database comprised of calibration process data for patients with similar physiology;
- said calibration procedure is performed during clinical catheterization as synchronized, simultaneous measurement of pressure values Pi, i=1, . . . N in the said oscillating traceable region(s) with a penetrating physical pressure measurement sensor(s) connected to a pressure monitor unit and a recording with said imaging device of the said oscillating traceable region;
- said pressure monitor unit and said imaging device being both controlled by calibration control unit;
- said calibration control unit is preferably a computer or a mobile device capable of connecting to both said imaging device and said pressure monitor unit connected to at least one pressure measurement sensor;
- said calibration procedure is followed by calibration process initiated by said calibration control unit. Said process includes, but is not limited to the identification of the said oscillating traceable regions inside the said T-Image recorded during said calibration procedure and fitting their movement to the pressure values Pi in these regions measured by the said penetrating physical pressure measurement sensors and processed by calibration control unit;
- in presence of the said calibration process, said continuous non-invasive measurements and calculations of the dynamically changing pressures inside a said person's body can be performed at any time or place by directing the said imaging device connected to the said end-user control unit to the same region as during the said calibration procedure and performing a recording which the said control unit will compare against the results of the said calibration process for the said patient and produce a calculated real-time pressure value series {P(ti)}i=1, . . . N;
- in absence of said calibration process, on the basis of the recorded image data for the said person the system is capable to estimate the said pressure using a database comprised of calibration process data for patients with similar physiology.
