Methods and apparatuses for adjusting three-dimensional (3D) dental model data of a patient's dentition to detect and remove one or more attachments on a dental structure (e.g., tooth) of the patient's dentition. These methods and apparatuses may be used for generating treatment plans for treating the patient's teeth, including for more accurately and efficiently aligning the patient's teeth.

In some embodiments, an example method or system consistent with the present disclosure may: obtain a desired property of a simulated trajectory of a virtual camera; receive a first video of a wound captured by a moving camera, the first video including a plurality of frames; use the desired property of the simulated trajectory of the virtual camera to analyze the first video to select at least two frames of the plurality of frames corresponding to the simulated trajectory of the virtual camera; use the desired property of the simulated trajectory of the virtual camera to select an order for the selected at least two frames; and rearrange the at least two frames based on the selected order to create a new video of the wound that represents the simulated trajectory of the virtual camera.

Methods for characterizing fluids from a patient. A time series of images of a conduit are received, and a conduit image region in the images is identified. A flow type of the fluids passing through the conduit may be classified as one of air, laminar liquid, and turbulent liquid by evaluating an air-liquid boundary of the fluid. A volumetric flow rate of the fluids in the conduit is estimated. The volumetric flow rate may be based on the classified flow type. A concentration of a blood component of the fluids passing through the conduit may be estimated based on the images. A proportion of the fluid that is blood may also be determined, and a volume of blood that has passed through the conduit within a predetermined period of time may be estimated based on the estimated total volumetric flow rate and the determined proportion.

A heterogeneous population of cells are separated and collected according to a method. The heterogeneous population of cells in a paramagnetic medium are placed in a fluidic channel in which the fluidic channel comprises two or more outlets. The heterogeneous population of cells in the fluidic channel are separated based on differences in magnetic susceptibility and density of the heterogeneous population of cells. Fluid comprising the separated cells is withdrawn from the two or more outlets using variable flow rates by fluidic pumps at respective ones of the two or more outlets simultaneously to fractionalize the fluid comprising the separated cells across the two or more outlets by manipulation of the variable flow rates relative to one another.

A retinal imaging system includes an eyepiece lens assembly, an image sensor, a dynamic fixation target viewable through the eyepiece lens assembly, and a controller coupled to the image sensor and the dynamic fixation target. The controller includes logic that causes the retinal imaging system to perform operations including: acquiring a first image of the eye, analyzing the first image to determine whether a misalignment between the eye and the eyepiece lens assembly is present; in response to determining the misalignment is present, adjusting a visual position of the dynamic fixation target to encourage the eye to rotate in a direction that compensates for the misalignment, and acquiring the retinal image of the eye after adjusting the visual position of the dynamic fixation target.

The present disclosure provides systems and methods to receiving OCT or IVUS image data frames to output one or more representations of a blood vessel segment. The image data frames may be stretched and/or aligned using various windows or bins or alignment features. Arterial features, such as the calcium burden, may be detected in each of the image data frames. The arterial features may be scored. The score may be a stent under-expansion risk. The representation may include an indication of the arterial features and their respective score. The indication may be a color coded indication.

A vehicle control device includes a tracking unit estimating a motion of a moving object, a model selection unit selecting a motion model corresponding to a moving object type, an abnormality determination unit determining a presence or absence of an abnormality of the estimation of the motion of the moving object based on the estimated moving object motion and the motion indicated by the motion model, and a control unit. A control mode in which the control unit controls traveling of a host vehicle when the abnormality determination unit determines that the abnormality is present differs from a control mode in which the control unit controls the traveling of the host vehicle when the abnormality determination unit determines that the abnormality is absent.

A method of updating the status of an insurance customer includes identifying a plurality of individuals with a first insurance status and delivering home testing kits to the plurality of individuals. Upon completion of the home testing kits, medical image information is received from a mobile communications device and processed to determine a state of a medical analysis region. Individuals with medical analysis regions in a differing state of criticality are identified. Healthcare providers may be provided with information indicating that there is a likelihood that the identified individuals are entitled to a second insurance status.

According some aspects, a secondary device may display secondary audiovisual content along with playback of audiovisual content on a primary device. For example, the secondary device may display an augmented reality application synchronized with the video. Aspects may predetermine a set of frame transition ranges for the video, where each respective frame transition is determined based on frames of the video that are determined to be substantially identical by a frame reference function and frames that are determined to be different. Two frames may be substantially identical even if they are different in the source video. This may be due to shortcomings in the frame reference function, or encoding/compression losses in transmission and playback of the video. Playback may be synchronized based on a first detected frame, but synchronization may be refined upon detecting a frame transition to a second frame that is no longer substantially identical to prior frames.

Disclosed are processes including receiving at least a first and a second image data record corresponding to a first and a second point in time and including a first and a second one or more images of a wound; obtaining an image of the wound from a particular point of view corresponding to the first point in time by analyzing the first image data record; generating a simulated image of the wound from the particular point of view corresponding to the second point in time by analyzing the second image data record; and generating a visual time series view of the wound including at least the image of the wound from the particular point of view corresponding to the first point in time and the simulated image of the wound from the particular point of view corresponding to the second point in time.
