MEDICAL INFORMATION PROCESSING APPARATUS, X-RAY CT APPARATUS, AND MEDICAL INFORMATION PROCESSING METHOD
A medical information processing apparatus according to an embodiment includes processing circuitry. The processing circuitry obtains image data rendering a blood vessel of a patient. The processing circuitry performs a fluid analysis on the obtained image data and calculates an index value related to a blood flow in the blood vessel with respect to each of a plurality of positions in the blood vessel. With respect to the index values to be calculated, the processing circuitry selects a position in which a first value is to be obtained from among the plurality of positions or selects a value serving as the first value from among the index values exhibited in positions. The processing circuitry causes a display to display the first value in a predetermined display region thereof used for displaying the first value.

CONSTITUTIVE EQUATION FOR NON-INVASIVE BLOOD PRESSURE MEASUREMENT SYSTEMS AND METHODS
The disclosed devices, systems and methods measure non-invasive blood pressure in a patient. Energy emissions, such as ultrasound or light, are emitted into tissues of the patient. The emitted energy reflects from various tissues, such as flowing blood and vessels, and can be detected, or received, to generate a reflected energy signal or data. The reflected energy can be processed, such as by using a constitutive equation, to calculate the blood pressure.
Blood flow function examination apparatus and X-ray diagnostic apparatus
According to one embodiment, there is provided an X-ray diagnostic apparatus which comprises an X-ray generation unit configured to irradiate an object with X-rays; an X-ray detection unit configured to detect X-rays applied by the X-ray generation unit and transmitted through the object; an image generation unit configured to generate an X-ray image based on X-rays detected by the X-ray detection unit; a recording unit configured to record pressure data acquired by using a pressure sensor provided on a guide wire; a measurement position setting unit configured to set a measurement position for a pressure by the pressure sensor using the X-ray image; and a display unit configured to display the X-ray image almost in real time and superimpose and display the measurement position set by the measurement position setting unit.
System and method for scanning for a second object within a first object using an adaptive scheduler
Method for scanning for second object on or within first object starts by receiving information on first object and second object. Task lists are generated that include at least one task action based on information on first object and second object. Based on task lists, beamer is then signaled to generate and send first signal to first probe unit to perform first beam firing. Receiver processes first data signal from first probe unit that is then analyzed to determine if first object is identified using processed first data signal. Upon determination that first object is identified, based on task list, beamer is signaled to generate and send second signal to second probe unit to perform second beam firing. Receiver processes second data signal from second probe unit that is then analyzed to determine if second object is identified using processed second data signal. Other embodiments are described.
Device for measuring blood flow
The invention relates to a measurement device for the blood flow of an individual, for example for the detection of bubbles. The device comprises an acoustic emitter and a case with an emission surface capping the acoustic emitter. The emission surface is terminated at one end by a clavicular contact portion perpendicular to the emission surface and suited for coming to rest against a clavicle bone of the individual and is terminated at another end by a shoulder contact portion perpendicular to the emission surface and suited for coming to rest against a bone of the shoulder of the individual. A vertical distance between the middle of an active zone of the emission surface and the clavicular contact portion is less than 20 mm. A transverse distance between the middle of the active zone and the shoulder contact portion is included between 20 and 50 mm.

Method and device for automatically predicting FFR based on images of vessel
The present disclosure is directed to a method and system for automatically predicting a physiological parameter based on images of vessel. The method includes receiving the images of a vessel acquired by an imaging device. The method further includes determining a sequence of temporal features at a sequence of positions on a centerline of the vessel based on the images of the vessel, and determining a sequence of structure-related features at the sequence of positions on the centerline of the vessel. The method also includes fusing the sequence of structure-related features and the sequence of temporal features at the sequence of positions respectively. The method additionally includes determining the physiological parameter for the vessel at the sequence of positions, by using a sequence-to-sequence neural network configured to capture sequential dependencies among the sequence of fused features.
METHODS AND SYSTEMS FOR ESTABLISHING RETROGRADE CAROTID ARTERIAL BLOOD FLOW
