Abstract:
Disclosed is a body impedance measurement apparatus. The impedance measurement apparatus provides a plurality of electrodes for measuring body impedance, senses electrodes, contacting with a body, from among the plurality of electrodes, and determines the use of the electrodes contacting with the body, depending on the sensing result.
Abstract:
The present disclosure describes a method for determining spinal instability, more particularly, a method for quantifying the type and extent of spinal instability in a standardized way. The disclosure also describes a method comprising measurement of the intervertebral rotation and intervertebral translation between a vertebrae pair using simple images, and from these measurements, determining if one or more vertebrae pair of the spine is unstable. Finally, the disclosure describes software that may be used to quantify the type and extent of spinal instability.
Abstract:
A method and system for performing video content analysis based on two-dimensional image data and depth data are disclosed. Video content analysis may be performed on the two-dimensional image data, and then the depth data may be used along with the results of the video content analysis of the two-dimensional data for tracking and event detection.
Abstract:
In a method and imaging device for ascertaining an absolute scan region on a patient, who is positioned on an examination table, for a subsequent medical imaging examination by operation of the medical imaging device, the height of the patient is ascertained, a relative examination region is ascertained, and the absolute scan region of the patient for the subsequent medical imaging examination is determined in a processor using the patient height and the relative examination region.
Abstract:
Methods and apparatus combine patient measurement data with demographic or physiological data of the patient to determine an output that can be used to diagnose and treat the patient. A customized output can be determined based the demographics of the patient, physiological data of the patient, and data of a population of patients. In another aspect, patient measurement data is used to predict an impending cardiac event, such as acute decompensated heart failure. At least one personalized value is determined for the patient, and a patient event prediction output is generated based at least in part on the personalized value and the measurement data. For example, bioimpedance data may be used to establish a baseline impedance specific to the patient, and the patient event prediction output generated based in part on the relationship of ongoing impedance measurements to the baseline impedance. Multivariate prediction models may enhance prediction accuracy.
Abstract:
Systems, methods and a sensor alignment mechanism are disclosed for medical navigational guidance systems. In one example, a system to make sterile a non-sterile optical sensor for use in navigational guidance during surgery includes a sterile drape having an optically transparent window to drape the optical sensor in a sterile barrier and a sensor alignment mechanism. The alignment mechanism secures the sensor through the drape in alignment with the window without breaching the sterile barrier and facilitates adjustment of the orientation of the optical sensor. The optical sensor may be aligned to view a surgical site when the alignment mechanism, assembled with the sterile drape and optical sensor, is attached to a bone. The alignment mechanism may be a lockable ball joint and facilitate orientation of the sensor in at least two degrees of freedom. A quick connect mechanism may couple the alignment mechanism to the bone.
Abstract:
A system and method for automatic detection of potential focal cortical dysplasias through magnetic resonance imaging. The method includes acquiring image data of a subject brain at a first resolution, analyzing the acquired image data to determine a thickness of cerebral gray matter, and matching the left cerebral hemisphere to the right cerebral hemisphere based on corresponding geometric features of the hemispheres. The method also includes generating a difference map comparing corresponding thicknesses of the hemispheres, identifying regions of abnormal differences in thickness as potential regions containing focal cortical dysplasias, and acquiring image data of the regions of abnormal differences in thickness at a second resolution. The method further includes generating images of the regions of abnormal differences in thickness from the acquired image data and displaying the images.
Abstract:
A radiation imaging apparatus has a camera installed on a gantry, and a method creates volume data of a subject through images of the subject photographed by the camera and calculates an optimum dose of radiation based on the volume data of the subject. The radiation imaging apparatus includes the gantry, and the camera installed on the gantry to photograph a subject.
Abstract:
A multi-sensor wireless abdominal monitoring system comprising a low-profile belt that fits around the abdomen and is embedded with specialized wireless sensors. The system is configured to continuously monitor a range of gastrointestinal and abdominal wall functions. The system wirelessly transmits data to an external device, such as a smartphone or computer for storage and download to a central server. The acquired data may be monitored remotely through specialized software that generates clinically interpretable information presented through a graphical user interface. The device provides data that are immediately actionable for a wide range of inpatients and outpatients with high prevalence disorders in varied clinical settings.
Abstract:
A smart phone is used to accomplish measurement of a wound surface area, when at least one flat marker device, which is a predefined reference, is placed near the wound and photographed by a smart phone.
