A system and method comprising several hardware and software components that work together to achieve the goal of performance prediction. The hardware components include neuroimaging collection hardware and a computing system. The neuroimaging hardware obtains the brain signals and sends this first set of data to a computational resource for further analysis. A second sent of data is the task performance scores of the participants. This second set is also set to the computational resource. The inventive system can predict a learning rate of target tasks for an individual from just a few minutes of off-task, resting-state neuroimaging data.

The present disclosure is directed to methods of predicting overall survival, monitoring, and selecting treatments for a glioblastoma (GBM) patient. The method of the present disclosure includes obtaining at least one morphometric image from the GBM patient, identifying at least one radiomic biomarker based on the at least one morphometric image, and determining an overall survival value based on the at least one radiomic biomarker.

There is provided a method for determining dementia risk factors by a server using deep learning. In this instance, the method for determining dementia risk factors includes acquiring biometric information from each subject corresponding to a first control group through a wearable device, acquiring measurement information for each subject corresponding to the first control group, deriving a first dementia risk factor based on the biometric information and the measurement information for each subject, and deriving a second dementia risk factor related to the first dementia risk factor via deep learning performed based on the biometric information related to the first dementia risk factor and control group information.

A photoacoustic imaging approach identifies, concurrently with ablation therapy, an extent of the ablation by measuring and rendering a necrotic extent of treated tissue in a treatment region. Laser pulsed light directed at the treatment region induces an acoustic (ultrasound) signal for differentiating ablated tissue from its non-ablative counterpart based on a photoacoustic spectrum variation. The acoustic signal indicates a range of necrotic extent based on a quantified ablated tissue contrast and a total contrast of both necrotic and non-necrotic tissue, defined as a fraction for computing a degree of necrosis. Generation of an image indicating the degree of necrosis allows continuous or near continuous feedback for ablation therapy guidance to ensure complete and effective ablation of the proper tissue in the treatment region.

A system and method for denoising experimental data originating from multiple acquisitions by a magnetic resonance imaging device, by analysis of selected principal components, to obtain a better compromise between the efficiency of the denoising and retention of the relevant information in the experimental data under consideration during their reconstruction to produce denoised experimental data. A selection criterion is based on the informative indicators quantifying the spatial information contained in images of scores associated with said principal components. The invention also provides for the capability to apply an adaptive filtering excluding the persistent spatial noise associated with each component selected.

An example apparatus includes a shell portion configured to be worn over a head of a subject. The shell portion defines a plurality of apertures. The apparatus also includes a plurality of spherical fiducial structures disposed on the shell portion. Each of the fiducial structures includes a first material doped with a second material. The second material is a contrast agent for magnetic resource imaging (MRI). The apparatus also includes a mounting structure disposed on the shell portion and configured to secure the shell portion to the head of the subject.

A method for performing magnetic resonance imaging on a subject comprises: injecting a contrast agent into a region of interest of the subject; applying a pulse sequence to the region of interest; collecting auxiliary data for the region of interest, the auxiliary data being related to one or more time-varying parameters of the subject within the region of interest; determining a temporal factor Φ from the auxiliary data; collecting imaging data for the region of interest, the imaging data being related to one or more spatially-varying parameters of the subject within the region of interest; determining a spatial factor Ur from the imaging data; modeling a multi-dimensional image sequence as I=UrΦ; and deriving at least a first metric and a second metric from the multi-dimensional image sequence I, the first metric and the second metric being associated with distinct perfusion-based imaging techniques.

There is provided a patient's cranial position monitoring and controlling device for controlling a magnetic resonance (MR) guided radiation source module via an MR-guided radiation controlling device connected to the patient's cranial position monitoring and controlling device and an MR-guided radiation system including a patient's cranial position monitoring and controlling device, which allows for better MR-imaging while allowing patient position monitoring close to the patient.

A biological measuring device includes a light source that emits first light illuminating an area on a living body, an imaging device that detects second light returned from the living body and acquires a first image including at least part of the living body, and a control circuit that controls the light source. If a specific part of the living body is not located in a predetermined coordinate range in the first image, the control circuit restricts emission of the first light from the light source. The predetermined coordinate range is set outside the area.
