6 results about "Anatomical structures" patented technology

The invention relates to a system and a method for analysis and evaluation of at least one anatomical structure in a medical image, said medical image representing at least a part of a patient or person, said system comprising image analysing means for calculating the volume and / or providing the shape of the at least one anatomical structure, and statistical analysing means for providing a confidence interval of the volume and / or the shape of the analysed anatomical structure(s) based on individual data of the patient or person, thereby quantifying the normality of said anatomical structure(s). By the present system and method a detailed and trustworthy confidence interval can be provided in connection with analysis and evaluation of a medical image of a patient, thereby illustrating the expected normality of the patient. The invention can be applied to images acquired from magnetic resonance imaging (MRI). One example of use is for diagnosing diseases and / or initial stages of diseases.

The invention brings forward a method for automatically positioning a standard tangent plane from an ultrasonic image. The method comprises the following steps: S103, constructing a radial component module to describe the anatomical structure of a target area, performing area dividing on the target area in the ultrasonic image by use of the radial component module, and obtaining a limitation area; S105, respectively detecting different anatomical structures in the limitation area by use of multiple classifiers trained by a machine learning method, and respectively obtaining detection results; S107, fusing the detection results by use of a fusion classier, and obtaining a fusion result; and S109, according to the fusion result, determining whether the ultrasonic image is the standard tangent plane. The method provided by the invention can effectively improve the detection accuracy.

The invention discloses a posterior reduction internal fixation system. The posterior reduction internal fixation system comprises two vertebral body orthopedic rods arranged in parallel and an adjusting device. During operation, the connecting rods of the two vertebral body orthopedic rods are connected with a vertebral body, and an occipital bone plate is connected with an occipital bone, so that the posterior reduction internal fixation system is connected with the occipital bone and the vertebral body; the base assembly is connected with a pedicle screw close to an occipital bone, and theconnecting assembly is connected with an occipital bone screw; the inclination angle between the occipital bone plate and the connecting rod is adjusted, specifically, the connecting rod is driven bythe first linear driving assembly to move, the first drag hook and the second drag hook are connected with two occipital bone screws on the occipital bone correspondingly, and the first linear drivingassembly is driven by the second linear driving assembly to move; the first linear driving assembly drives the connecting rod and the first drag hook and the second drag hook on the connecting rod tomove, the occipital bone is lifted and dragged, the inclination angle between the occipital bone plate and the connecting rod is made to conform to the anatomical structure of the occipital bone andthe cervical vertebra of the human body, and posterior reduction internal fixation is achieved.

The invention relates to a model for calculating and evaluating eye crystal dosage. The model comprises a head model and eyeball models, two eye socket models are arranged on the head model and used for respectively placing a left eyeball model and a right eyeball model, and the head model sequentially comprises an external soft tissue model, a skull model and an internal soft tissue model from outside to inside. The external soft tissue model represents a skin, the skull model represents a skull, and the internal soft tissue model represents a skull internal tissue; each eyeball model comprises an eyelid model, a cornea model, an anterior chamber model, a crystalline lens model, a vitreous body model, a retina model, a choroid model and a sclera model; the head model and the eyeball models are provided with protective devices and radiation dosimeters. The eyeball model has a detailed anatomical structure, the size of the eyeball model is equivalent to the size of a real eyeball, the density and the element proportion of each tissue are derived from medical data, and fine calculation of the eye crystal dosage, radiation risk evaluation and radiation protection optimization work canbe further perfected.

Methods of treating musculoskeletal deformities of an anatomical structure in a quadruped animal with botulinum toxin are described. Such deformities can be rotational or flexural. Such deformities can be acquired or congenital. Such anatomical structures include a limb, neck, torso, and / or pelvis of the quadruped animal.
