According to one embodiment, a medical image processing apparatus includes an acquiring unit, an identifying unit, and a display controller. The acquiring unit acquires volume data indicating the state of a three-dimensional region including a mass portion and a plurality of blood vessels derived from the mass portion in a subject. The identifying unit specifies a region corresponding to the mass portion and the blood vessels in the volume data as a region of interest. The identifying unit identifies the mass portion and each of the blood vessels in the region of interest. The display controller assigns a different display mode to at least one of the mass portion and the blood vessels.

SYSTEM AND METHOD FOR MAPPING ARRHYTHMIC DRIVER SITES
20210401344 · 2021-12-30 ·

Arrhythmic foci and other driver sites can be mapped using a multi-dimensional catheter. For instance, using a clique of three or more electrodes on the multi-dimensional catheter, an electroanatomical mapping system can identify a maximum bipolar voltage and an average unipolar voltage. The ratio of the average unipolar voltage to the maximum bipolar voltage can be interpreted as an indication of whether a cardiac location is an arrhythmic focus. Alternatively, an evaluation region can be defined about location in the patient's heart. The evaluation includes a plurality of rods, each associated with a respective E-field loop having a respective maximum and minimum amplitude bipole axes, with the rods being defined by the maximum amplitude bipole axes. For a sufficient number of rods within the evaluation region, a focus score for the evaluation region can be computed to reflect rod orientation consistency within the evaluation region.

Fetal monitoring hub

In the present invention, a system and associated method is provided for monitoring fetal vital parameters. The system includes a base unit, a monitoring hub including a digital signal processor/controller and operably connected to the base unit by a single channel digital signal protocol cable, e.g., a USB cable, and a number of fetal monitoring sensors operably connected to the monitoring hub. The controller processes the signals from the sensors into a single USB protocol which can be sent along a single cable to the base unit. The USB cable allows power to be supplied to the hub in order to charge a battery used to operate the hub and the sensors connected to the hub when disconnected from the base unit to allow the patient using the hub to move freely about the base unit, with all sensor signals from the hub being wirelessly transmitted to the base unit.

A method for fluorescence-based imaging of a target to detect contamination and/or pollutants is disclosed. The method includes labelling a pre-selected biomarker at the target, illuminating the target with excitation light emitted by an excitation light source and having at least one wavelength or wavelength band causing at least the pre-selected biomarker to fluoresce, detecting fluorescence emissions of at least the pre-selected biomarker with an image detector of a handheld imaging device, and determining the presence, location, and/or quantity of contamination and/or pollutants on and/or in the illuminated target based on the detected fluorescence emissions of at least the pre-selected biomarker.

PATIENT MONITORING SYSTEM

A patient monitoring system includes an inflatable cuff, a gas reservoir containing a compressed gas, and a sensor. When the inflatable cuff is coupled to a wearer, the gas reservoir supplies gas to the inflatable cuff to inflate the inflatable cuff via gas pathways. As the inflatable cuff inflates, a patient monitor can receive blood pressure data from the sensor and use the blood pressure data to determine the blood pressure of the wearer. The patient monitor can also receive blood pressure data during deflation of the inflatable cuff to determine the blood pressure of the wearer.
