Alternative-reality devices and methods are disclosed for establishing and visualizing historical sites of vascular access, which are useful for evaluating potential sites of vascular access and improving the successes of obtaining vascular access. For example, an alternative-reality device includes anatomical target-defining instructions and vascular access site-tracking instructions in memory of the alternative-reality device for execution by one-or-more processors thereof. The alternative-reality device also includes a patient-facing camera configured to capture images or video frames for generating an anatomical target in the memory per the anatomical target-defining instructions and tracking the historical sites of vascular access in relation thereto with the vascular access site-tracking instructions. With a display screen of the alternative-reality device, a user can instantly see an environment including an anatomical portion of a patient to which the anatomical target corresponds, as well as graphical elements anchored to the anatomical portion indicating the historical sites of vascular access.

The present disclosure relates to a method for predicting biomarker expression from a medical image. The method for predicting biomarker expression includes receiving a medical image, and outputting indices of biomarker expression for the at least one lesion included in the medical image by using a first machine learning model.

A measurement system includes: a mounting member configured to be mounted on a measurement target portion of a living body and including a plurality of holding units configured to hold a plurality of magnetic sensors such that the plurality of magnetic sensors face the measurement target portion; an image capturing unit configured to capture images of markers arranged in arrangement regions of the plurality of holding units of the mounting member mounted on the measurement target portion, in the measurement target portion; a moving mechanism unit configured to move the image capturing unit relative to the measurement target portion on which the mounting member is mounted; and a derivation unit configured to derive three-dimensional position information on the plurality of magnetic sensors held by the plurality of holding units relative to the measurement target portion, based on the captured images of the markers.

Systems and methods for discriminating between malignant and benign pigmented skin lesions based on optical analysis using spatial distribution maps, morphological parameters, and additional diagnostic parameters derived from images of tissue lesions. A handheld optical transfer diagnosis device is disclosed capable of capturing a series of reflectance images of a skin lesion at a variety of angles of illumination and observation.

Systems and methods for generating MRI images of the lungs and/or airways of a subject using a medical grade gas mixture comprises between about 20-79% inert perfluorinated gas and oxygen gas. The images are generated using acquired .sup.19F magnetic resonance image (MRI) signal data associated with the perfluorinated gas and oxygen mixture.

An MR Spectroscopy (MRS) system and approach is provided for diagnosing painful and non-painful discs in chronic, severe low back pain patients (DDD-MRS). A DDD-MRS pulse sequence generates and acquires DDD-MRS spectra within intervertebral disc nuclei for later signal processing and diagnostic analysis. An interfacing DDD-MRS signal processor receives output signals of the DDD-MRS spectra acquired and is configured to optimize signal-to-noise ratio by an automated system that selectively conducts optimal channel selection, phase and frequency correction, and frame editing as appropriate for a given acquisition series. A diagnostic processor calculates a diagnostic value for the disc based upon a weighted factor set of criteria that uses MRS data extracted from the acquired and processed MRS spectra for multiple chemicals that have been correlated to painful vs. non-painful discs. A display provides an indication of results for analyzed discs as an overlay onto a MRI image of the lumbar spine.

This system is a system for analyzing blood flow which imposes a boundary condition relating to the blood flow to three dimensional shape data of a target vascular site of a subject and divides a lumen of the target vascular site into meshes for obtaining state quantities of the blood flow at each mesh position by means of computation, having: a labeling unit, by a computer, for reading out the three dimensional shape data on the lumen of the target vascular site, and labeling a plurality of vascular elements included in the target vascular based on a size of the cross-sectional area of each of the vascular elements; wherein, the computation of the state quantities is carried out by varying a level of mesh detail for each vascular element based on the labeling according to the size of the cross-sectional area.

A system and method for analyzing scan data of a lung and presenting a lung candidacy report. The lung candidacy report includes determinations represented visually of whether lung lobes are suitable candidates for a bronchoscopy guided lung volume reduction procedure. The lung candidacy report includes emphysema values and fissure integrity determined from the scan data.

An image display apparatus includes: an input-output interface that obtains medical images of a same target region taken through serial radiography along a time axis; and a hardware processor that: executes a time-series replay display of the medical images obtained by the input-output interface, and displays a position reference at a fixed position on a screen, the position reference being superimposed on each of the medical images during the replay display.

Systems and methods for real-time tracking of photoacoustic sensing are provided. In one aspect, a method for performing in vivo analysis of a subject is provided. The method includes directing an electromagnetic excitation toward a subject to be analyzed, and acquiring, with an ultrasound probe, data about resultant waves caused by the electromagnetic excitation. The method also includes processing the acquired data to extract information related to properties of tissues in the subject, and comparing the information related to the properties of tissues in the subject using a set of criteria. The method also includes generating a report about a condition of the subject based on the comparison of the information related to properties of the tissues in the subject.
