A Sparsity and Smoothness enhanced Method Of Optimized electrical TomograpHy (s-SMOOTH) based reconstruction technique to improve the spatial resolution and localization accuracy of reconstructed brain images is described. Also described is a graph Fractional-Order Total Variation (gFOTV) based reconstruction technique to improve the spatial resolution and localization accuracy of reconstructed brain images.

A method comprises providing a current state image and at least one reference image, taken from a similar angle range. The image and the at least one reference image are superimposed and a visual representation visualizing the relation between the image and the reference image is provided in order to track displacements of the bone during subsequent operation steps. A system is provided which can use the image data to track displacements and determine deviation from a current state of the elements in question to a target state.

Disclosed is a method and system for three-dimensional tracking of a target located within a body, the method performed using at least one processing system. A two-dimensional scanned image of the body including the target is processed to obtain a two-dimensional image of the target. A first present dataset of the target is predicted using a previous dataset of the target and a state transition model, the first present dataset includes a three-dimensional present position value of the target. A second present dataset of the target is measured by template-matching of the two-dimensional image of the target with a model of the target. A third present dataset of the target is estimated by statistical inference using the first present dataset and the second present dataset. The previous dataset of the target is updated to match the third present dataset.

A quantification system (300) is described that includes: at least one input (310) configured to provide at least one input medical image and provide a location of interest in the at least one input medical image; and a mapping circuit (325). The mapping circuit (325) is configured to: compute a direct quantification result from the location of interest of the at least one input medical image to a quantification of interest and output a direct first quantification result therefrom; generate a saliency map as part of the computation of the direct quantification result; and derive a segmentation from the saliency map, such that the segmentation independently generates a second quantification result that is within a result range of the direct first quantification result.

A method for characterising motion of one or more objects in a time ordered image dataset comprising a plurality of time ordered data frames, the method comprising: selecting a reference data frame from the plurality of time ordered data frames (210); extracting a plurality of image patches from at least a part of the reference data frame (220); identifying a location of each image patch of at least a subset of the plurality of image patches in each data frame (230); defining, based on the identified locations, a mesh for each data frame, wherein vertices of each mesh correspond to respective identified locations of image patches in the corresponding data frame (240); and deriving, from the meshes, a motion signature for the time ordered image dataset, the motion signature characteristic of the motion of the one or more objects in the plurality of time ordered data frames (250).

A cell observation system includes an imaging element that acquires images of the inside of a culture container in which cells are cultured, the imaging element acquiring the images over time; a computer configured to: quantitatively analyze a culture state of the cells cultured in the culture container on the basis of each of the images acquired by the imaging element; and statistically analyze the quantitatively analyzed data; and a display that displays statistical analysis results in the culture container within a plurality of subculture periods obtained by the computer in a manner allowing comparison of the statistical analysis results.

A performance scanning system that operates to detect and measure surface parameters of a portion of an athlete and uses the surface parameters to determine the likelihood that the athlete's physical performance has been or will be impaired.

Provided is an endoscope system capable of preventing a detection target from being overlooked in the case of using an automatic detection function for the detection target, and an operation method for the endoscope system. A comparison processing unit 74 performs comparison processing of comparing first-diagnosis identification information acquired at a first diagnosis with second-diagnosis identification information acquired at a second diagnosis that is different from the first diagnosis. A notification control unit 76 performs, if a determination is made that there is a difference in a detection target between the first diagnosis and the second diagnosis as a result of the comparison processing, control to make a notification about an oversight of the detection target.

A method, an apparatus, and a computer program for determining a refractive error of an eye of a user are provided. The method for determining the refractive error of the eye of the user, wherein the eye of the user has a choroid, includes: ascertaining at least one value for a layer thickness of the choroid of the eye of the user over at least one region of the choroid; and determining a value for the change in the refractive error of the eye only from at least two values for the layer thickness of the choroid which were each ascertained at different times for the at least one region of the choroid, wherein the at least one region is selected from a nasal perifoveal region or a nasal parafoveal region.
