The disclosure herein relates to systems, methods, and devices for medical image analysis, diagnosis, risk stratification, decision making and/or disease tracking. In some embodiments, the systems, devices, and methods described herein are configured to analyze non-invasive medical images of a subject to automatically and/or dynamically identify one or more features, such as plaque and vessels, and/or derive one or more quantified plaque parameters, such as radiodensity, radiodensity composition, volume, radiodensity heterogeneity, geometry, location, perform computational fluid dynamics analysis, facilitate assessment of risk of heart disease and coronary artery disease, enhance drug development, determine a CAD risk factor goal, provide atherosclerosis and vascular morphology characterization, and determine indication of myocardial risk, and/or the like. In some embodiments, the systems, devices, and methods described herein are further configured to generate one or more assessments of plaque-based diseases from raw medical images using one or more of the identified features and/or quantified parameters.

A carrier positioning device includes a carrying base (100) and a carrier (200). A clamp (110) is arranged on the carrying base (100) and a protruding hook (113) protrudes from one side of a distal end (111) of the clamp (110). The carrier (200) has a pipe (210), and a joint (220) is disposed at one end of the pipe (210). The protruding hook (113) hooks one side of the joint (220) so that at least another portion of the carrier (200) is in contact with the carrying base (100). Accordingly, the carrier (200) can be quickly installed or be removed along a lateral direction.

The medical imaging apparatus of the present invention includes a bath tank for accommodating a test subject, the test subject being at least a portion of a body of a human subject; a measurement device movable in a predetermined direction, the measurement device including ab group of elements to emit a radiation wave into the bath tank and receive a scattered radiation wave; and a control unit for measuring by the measurement device when at least one of a location of the test subject within a plane orthogonal to the predetermined direction, a location of the test subject in the predetermined direction, and continuity of data measured by the measurement device satisfies a predetermined condition. Because of this configuration, the medical imaging apparatus is able to acquire data covering the entire measurement target site.

A support system configured to support the lower extremities of a patient, for example during radiotherapy and imaging procedures, and methods for employing the same is provided. The support system includes a knee support apparatus and a foot support apparatus, each of which may be used together or independently in order to customize the support needed for the particular procedure. When used on the patient table of an appropriate imaging or treatment modality, the support system is configured to allow the clinician to independently adjust the knee support and foot support's positioning in the superior-inferior axis of the patient table in both a gross and fine manner for optimal positioning of the patient for the target procedure. The robust adjustment capabilities of the support system enable enhanced patient comfort, setup reproducibility, and workflow efficiency.

A data processing apparatus according to an embodiment includes acquisition circuitry and specification circuitry. The acquisition circuitry is configured to acquire a detector signal containing a first component that is based on Cherenkov light and a second component that is based on scintillation light. The specification circuitry is configured to specify timing information about generation of the detector signal by curve fitting to the first component.

The present application discloses a method for detecting an abnormity in a ray source in a CT system, comprising obtaining scanning data obtained from at least two scans that are performed by a medical device, the medical device including a ray source configured to generate a plurality of rays and a detector configured to detect the plurality of rays; determining, based on a difference of the scanning data, a status characteristic index of the ray source; and determining whether abnormity exists in the ray source based on the status characteristic index.

A method and system for using in a Positron Emission Tomography (PET) system. The PET system comprises at least one processor and a storage. The PET system comprises an acquisition module and a processing module. The acquisition module is configured to acquire a PET data set corresponding to a target object. The acquisition module comprises a first light sensor array, a second light sensor array, and a scintillator array. The processing module is configured to determine a three-dimensional position of an incidence photon based on the PET data set. The first number of light sensors in the first light sensor array and the second number of light sensors of the second light sensor array is less than the number of scintillator of the scintillator array.

The present invention provides an image display method with which a structure of an imaging object can be easily understood on the basis of volume data. An image display method according to an aspect of the present invention includes obtaining photoacoustic image data, generating a first photoacoustic image corresponding to a first spatial region on the basis of photoacoustic image data and a second photoacoustic image corresponding to a second spatial region having a different thickness in a viewing direction of rendering from a thickness of the first spatial region and having a spatial region overlapped with the first spatial region on the basis of the photoacoustic image data, and generating and displaying a parallel image in which the first photoacoustic image and the second photoacoustic image are arranged side by side.

A method of spectrometric analysis comprises obtaining one or more sample spectra for an aerosol, smoke or vapour sample. The one or more sample spectra are subjected to pre-processing and then multivariate and/or library based analysis so as to classify the aerosol, smoke or vapour sample. The results of the analysis are used for various surgical or non-surgical applications.

Methods and systems are provided for detecting patient motion during a diagnostic scan. In one example, a method for a medical imaging system includes obtaining output from one or more patient monitoring devices configured to monitor a patient before and during a diagnostic scan executed with the medical imaging system, receiving a request to initiate the diagnostic scan, tracking patient motion based on the output from the one or more patient monitoring devices, and initiating the diagnostic scan responsive to patient motion being below a threshold level.
