Abstract: Systems and methods for determining a disease state of image elements are disclosed herein. An example method may include providing quantitative and non-quantitative images, determining a correspondence map of the quantitative images to an atlas, and determining candidate elements of the quantitative images by comparing the elements of the quantitative images to atlas elements of the atlas. The example method may also include localizing the candidate elements in the non-quantitative images, classifying the candidate elements based on properties of the non-quantitative images, and determining a disease state of the candidate elements.

Abstract: Methods, systems, products, devices, and/or apparatus generally related to distortion correction of multiple MRI images based on a full body reference image. An example method for distortion correction of multiple MRI images based on a full body reference image may include acquiring at least one reference image of a subject using a magnetic resonance imaging system, storing a correction field map based on the at least one reference image, the correction field map including information regarding a correction field for each of a plurality of portions of the subject, acquiring a plurality of images by the magnetic resonance imaging system, each of the plurality of images corresponding to a respective portion of the subject, and while acquiring each of the plurality of images, applying a correction field specified by the correction field map for the respective portion of the subject.

Abstract: A system for detecting a chemical substance of interest among a plurality of different chemical substances comprises an inlet, an ionization module, a high-field asymmetric waveform ion mobility spectrometry (FAIMS) cell, and optionally a detector. A focussing module and/or a flow control gas supply can be provided. The system has example applications for molecules including ?-9-tetrahydrocannabinol (THC), its metabolites and/or other substances of interest from a breath of a subject or from a breath sample obtained from a subject.

Abstract: A system for collecting cannabis and the psychoactive component tetrahydrocannabinol from a sample of exhaled breath is disclosed. Single or multiple exhaled breaths are conditioned by removing contaminants, and regulating flow rate and/or pressure to collect a sample of tetrahydrocannabinol for timely local or remote analysis. The cannabis detection system comprises a containment trap for removing interfering materials from the breath of the subject and a collection component for sampling components of breath introduced into the system through the containment trap for analysis to determine a presence of THC in the breath.

Abstract: A controlled substance Intercept system for collecting and detecting levels of one or more controlled substances in the breath of a subject and intercepting electric operation of a device, comprising: a sample capture module; a THC identification module; and an intercept module. The THC identification module sends an electric or optical signal to the intercept module if a level of controlled substance present in a sample captured in the sample capture, module exceeds a set threshold, for use in applications to enable or disable operation of equipment such as motor vehicles and construction equipment, and to enable or disable access to locations where impairment would pose a hazard, such as air or marine traffic control centers.

Abstract: A system for collecting cannabis and the psychoactive component tetrahydrocannabinol or other controlled substances from a sample of exhaled breath. Single or multiple exhaled breaths are conditioned by removing contaminants, and regulating flow rate and/or pressure to collect a sample of tetrahydrocannabinol for timely local or remote analysis using FAIMS. The cannabis detection system comprises a containment trap for removing interfering materials from the breath of the subject and a collection component for sampling components of breath introduced into the system through the containment trap for FAIMS analysis to determine the level of THC or other controlled substance in the breath.

Abstract: Apparatuses and methods for diffusion weighted imaging using phantoms are disclosed herein. An example phantom may include a reference member disposed within a housing, the reference member having a rod-like shape extending parallel to a long axis of the housing, the reference member formed from a material comprising a plurality of microchannels arranged longitudinally along at least a portion of the rod-like shape, and at least a portion of the housing may be formed to emulate a shape of a human torso.
