摘要: A method for adaptive treatment planning is provided. The method may include obtaining a planning image volume of a subject, a treatment image volume of the subject, and a first treatment plan related to the planning image volume of the subject, each of the planning image volume and the treatment image volume including an ROI of the subject. The method may also include registering the planning image volume and the treatment image volume, and determining a first contour of the ROI in the registered planning image volume and a second contour of the ROI in the registered treatment image volume. The method may also include evaluating whether an error exists in at least one of the registration or the contour determination based on the first contour and the second contour, and determining a second treatment plan with respect to the treatment image volume based on the evaluation result.

摘要: The present disclosure relates to an artificial intelligence field using a neural network, and publishes a method for confirming a cup-disc ratio based on a neural network, an apparatus, a computer device, and a computer readable storage medium. The method includes: obtaining a retinal image, and detecting an optical disc region in the retinal image to obtain the optical disc region; inputting the optical disc region into a pre-trained neural network to obtain a prediction cup-disc ratio and segment images of an optical cup and an optical disc; computing a cup-disc ratio based on the segment images of the optical cup and the optical disc; and confirming a practical cup-disc ratio based on the prediction cup-disc ratio and the computed cup-disc ratio.

摘要: Preoperative planning techniques are described such as for hip surgery. Rather than pre-operatively planning by reorienting a model of the boundaries of the acetabulum derived from a 3D medical image, the proposed solution reorients portions of the 3D medical image itself and simulates one or more x-ray images using the reoriented 3D data. Optionally, simulated x-ray(s) of the un-modified CT scan may also be generated for comparison purposes. The user then measures acetabular metrics on the simulated x-ray(s) in order to determine the radiographic outcomes that a given magnitude and direction of reorientation would achieve. By iteratively selecting a reorientation and measuring the simulated x-ray(s), an optimal reorientation plan is determined by the user.

摘要: The present disclosure provides an onboard object dimensioning system for a vehicle, such as a lift truck. The vehicle may have one or more sensors (e.g., a radar system, an acoustic sensor, an image capture system, LIDAR, microwave, etc.) to generate and transmit a signal toward an object on the vehicle, which is received as a feedback signal corresponding to a reflection from one or more surfaces of the object. Control circuitry receives data from the sensors including signal characteristics of the feedback signal. The data is converted into multiple dimensions corresponding to the one or more surfaces of the object, which are employed to determine a shape, volume, orientation, or area of the one or more surfaces of the object corresponding to the first and second dimensions.

摘要: At least one embodiment of a method for dynamically assisting a practitioner in preparing a dental bone grafting operation, the method comprising:—providing an image representing a 3D volume of a portion of a jaw member where bone grafting is to be carried out;—adding to the image a representation of a 3D virtual object representing dental bone graft material;—estimating a value of a geometric characteristic relating to the bone graft material to be used, as a function of geometric characteristics of the represented 3D virtual object;—enabling a user to modify the representation of the 3D virtual object; and—upon modification of the representation of the 3D virtual object, updating the estimated value of the geometric characteristic, according to the modification of the representation of the 3D virtual object, the estimated value assisting the practitioner in determining the dental bone graft material needed.

摘要: According to one embodiment, a medical image processing apparatus includes first specifier, second specifier, determiner and display controller. First specifier collates an ischemic region calculated from a blood vessel visualized into a three-dimensional image in a plurality of phases with a dominating region of the blood vessel, and specifies a culprit vessel in the ischemic region. Second specifier specifies a culprit stenosis in the culprit vessel based on a pressure index calculated from the blood vessel. Determiner determines a connection position to connect a bypass vessel that makes a detour around the culprit stenosis. Display controller displays the determined connection position on a display.

摘要: The present disclosure relates to a system (100) for scoring motion of a heart wall (214, 218). The system (100) includes an imaging system (102) operable to acquire a first image (230) of the heart wall (214, 218) at a first time and a second image (240) of the heart wall (214, 218) at a second time. A processor (108) is provided to identify a first set of contour data in the first image (230); and a second set of contour data in the second image (240). The processor (108) defines at least one element (Ei) representing a cardiac cyclic change in a section of the heart wall (214, 218) in dependence on the first and second sets of contour data. Each element (Ei) is analysed to generate at least one metric which is compared with a reference data model to score the motion of the corresponding section of the heart wall (214, 218). The disclosure also relates to a method of scoring motion of a heart wall (214, 218); and a non-transitory computer-readable medium.

摘要: A meniscus projection plane setting apparatus, a meniscus projection plane setting method, and a meniscus projection plane setting program appropriately set a projection plane when generating a projection image of a meniscus from a three-dimensional image including a knee joint. An image acquisition unit acquires the three-dimensional image of the knee joint. A plane setting unit sets a plane that approximates a joint surface of the knee joint as the projection plane for generating the projection image by projecting the meniscus at the knee joint included in the three-dimensional image.

摘要: Three-dimensional (3D) imaging systems and methods are described for implementing virtual grading of package walls in commercial trailer loading. The 3D imaging systems and methods comprise capturing, by a 3D-depth camera, 3D image data of a vehicle storage area. A package wall is determined, based on the set of 3D image data and by a 3D data analytics application (app) executing on one or more processors communicatively coupled to the 3D-depth camera, a package wall within the vehicle storage area. A wall grade is assigned to the package wall, where the package wall is defined within the set of 3D image data by a plurality of packages each having a similar depth dimension, and wherein the package wall has a wall height.

摘要: In some embodiments, spinal disc degeneracy is diagnosed according to a decay variance map generated by determining a variance in T2 decay over time within each pixel or pixel subset of an MRI image. A region of interest may be defined as including nucleus pulposus (NP) and annulus fibrosus (AF) areas, and excluding cartilaginous endplate (EP) areas of a disc. A decay variance for a pixel or groups of pixels is calculated by determining ratios between consecutive intensity values of the T2 signal, determining differences between consecutive ratios, and summing the absolute values of the determined differences. Decay variance mapping may be used to diagnose degeneracy in other tissues, such as in joints.
