A therapeutic system comprising a therapeutic applicator for treating living tissues and an observation unit for determining the position of the applicator. The therapeutic energy applied from the applicator to the living tissues is controlled in accordance with data representing the position of the applicator, determined by the observation unit. It is therefore easy to operate the system even if the applicator and the observation unit (e.g., an MRI apparatus) are used at the same time. The image of the living tissues remains clear during the use of the therapeutic applicator.

The invention includes a method and system to provide a competitive pricing tool so that automobile dealers can more efficiently and effectively price their used vehicles. The system achieves the optimal sales price by obtaining the relevant pricing and mileage of vehicles for sale that are similarly situated to the focus vehicle. Once the information is obtained, the system creates a value ranking for each of the vehicles for sale and for the focus vehicle. The user is then able to revise the focus vehicle pricing to determine the optimal sales price. The invention also provides information to the potential customer about the vehicle for sale, including information relating to other similar vehicles for sale in a particular geographical area that can be accessed at the point of sale, or by the customer at a later time and place. The party offering the product for sale is informed each time the customer accesses the information, thereby indicating the level of interest by the customer. The invention further provides a stocking tool to determine when to purchase additional vehicles for inventory, a merchandising view to review and revise advertisements, and an automatic description generator for the particular vehicle being sold.

An electronic endoscope system which captures an image of an object and displays the same on a display device is provided with a noise reduction system. The noise reduction system reduces noise included in a frame of an image signal for each color component. The noise-reduced color components are stored in a buffer, and then output as a video signal to be transmitted to a display where a color image of the object is displayed.

The present invention relates to radiographic imaging apparatus for taking X-ray images of an object. In various two-panel radiographic imaging apparatus configurations, a front panel and back panel have substrates, arrays of signal sensing elements and readout devices, and passivation layers. The front and back panels have scintillating phosphor layers responsive to X-rays passing through an object produce light which illuminates the signal sensing elements to provide signals representing X-ray images. The X-ray apparatus has means for combining the signals of the X-ray images to produce a composite X-ray image. Furthermore, the composition and thickness of the scintillating phosphor layers are selected, relative to each other, to improve the diagnostic efficacy of the composite X-ray image. Alternatively, a radiographic imaging apparatus has a single panel having arrays of signal sensing elements and readout devices and scintillating phosphor layers that are disposed on both sides of a single substrate. The present invention further relates to various embodiments of indirect dual-screen DR flat-panel imager apparatus that provide single-exposure dual energy imaging.

Improved optical devices and methods transmit optical images along elongate optical paths with relatively limited cross-sectional dimensions using an improved objective, relay, and ocular systems. In a first aspect, at least one intermediate image formed within an optical component, rather than being formed in a gap between optical components. In a preferred embodiment, a first intermediate image is formed within glass of the most proximal objective lens, with the first intermediate image extending axially along a curved image location within the glass. The last intermediate image may similarly be disposed within a distal lens of the ocular system. By making use of a first and/or last intermediate image disposed in this manner within a lens, endoscopes can exhibit a significantly larger Numerical Aperture than known endoscopes having similar cross-sectional dimensions. In a second aspect, the ocular system allows independent adjustment of diopters, magnification, X-Y positioning, and rotation orientation of the captured image while introducing minimal aberrations.

A method of automatically capturing images with precision uses an intelligent mobile device having a camera loaded with an appropriate image capture application. When a use initializes the application, the camera starts taking images of the object. Each image is qualified to determine whether it is in focus and entirely within the field of view of the camera: Two or more qualified images are captured and stored for subsequent processing. The qualified images are aligned with each other by an appropriate perspective transformation so they each fill a common frame. Averaging of the aligned images reduces noise and a sharpening filter enhances edges, which produces a sharper image. The processed image is then converted into a two-level, black and white image which may be presented to the user for approval prior to submission via wireless or WiFi to a remote location.

Input data comprising a video signal is processed using a combination of a known image processing method to deblur, or sharpen, the image and convolution with Pixon™ kernels for smoothing. The smoothing process utilizes a plurality of different size Pixon™ kernels which operate in parallel so that the input data are convolved with each different Pixon™ kernel simultaneously. The smoothed image is convolved with the point response function (PRF) to form data models that are compared against the input data, then the broadest Pixon™ kernel that fits the input data within a predetermined criterion are selected to form a Pixon™ map. The data are smoothed and assembled according to the Pixon™ map, then are deconvolved and output to a video display or other appropriate device, providing a clearer image with less noise.

Devices, systems, and methods for treating and/or determining appropriate prescriptions for one or both eyes of a patient are particularly well-suited for addressing presbyopia, often in combination with concurrent treatments of other vision defects. High-order spherical aberration may be imposed in one or both of a patient's eyes, often as a controlled amount of negative spherical aberration extending across a pupil. A desired presbyopia-mitigating quantity of high-order spherical aberration may be defined by one or more spherical Zernike coefficients, which may be combined with Zernike coefficients generated from a wavefront aberrometer. The resulting prescription can be imposed using refractive surgical techniques such as laser eye surgery, using intraocular lenses and other implanted structures, using contact lenses, using temporary or permanent corneal reshaping techniques, and/or the like.

The invention relates to a method for establishing a human knee joint three-dimensional simulation model in combination with CT (Computed Tomography) and MRI (Magnetic Resonance Imaging), and belongs to the technical field of medical images. The method comprises six steps of CT image acquisition, MRI image acquisition, data storage, CT two-dimensional image importing and three-dimensional model establishment, MRI two-dimensional image importing and three-dimensional model establishment, and knee joint anatomy simulation model registration and modification. The method combines the advantages of CT and MRI scanning, so that the scanning is convenient and fast, the images are clear, the dissection relation is definite, the density resolution is very high, and the scanning range is very wide. According to the method, two sets of images are registered through a three-dimensional image registration technology, three-dimensional coordinate systems of two types of images are unified by fitting point cloud contours and anatomical feature points of femurs, tibias and fibulas, and registration is performed through a registration module to obtain a double-lower-limb full-length knee joint three-dimensional digital model with structures of bones, cartilages, meniscuses, ligaments, muscle tendons and the like.
