A signal detector detects signals transmitted from signal generators disposed in a radiation detecting cassette, and a distance calculator calculates the distance between a radiation source and a radiation detector based on the signals detected by the signal detector. A determining unit determines whether the detected distance matches a predetermined distance from the radiation source to the radiation detector when a radiation image is captured. If the detected distance does not match the predetermined distance, the determining unit outputs, to a warning unit, a warning signal indicating that the detected distance does not match the predetermined distance, and also outputs a control signal for equalizing the detected distance with the predetermined distance, to a radiation source movement controller.

An aligning bite of an X-ray device for aligning a subject to an X-ray imaging point and an X-ray device having the same are disclosed. The aligning bite of an X-ray may include a support unit being rotatably connected to a bite stand supporting the aligning bite, and a bite unit being rotatably connected to the support unit, wherein the support unit may include a link frame supporting the bite unit by connecting the bite unit to the bite stand, a first joint rotatably connecting one side of the link frame to the bite stand, a second joint rotatably connecting the bite unit to another side of the link frame, and a third joint being provided between the first joint and the second joint so as to allow the link frame to be folded.

A coin or token image acquiring apparatus includes a coin moving unit for receiving coins in a sequential manner and translating each coin to a predetermined station. A time sensor unit detects the position of the respective coins in the coin moving unit and provides a timing signal that can activate an image apparatus unit positioned at the predetermined station. A light emitting apparatus is positioned to illuminate the coin face at the predetermined station so that the image apparatus can capture an illuminated image of the face of the coin. A storage unit can store a reference image of an authenticated coin image where by a comparator unit can compare the captured image of the coin with the authenticated coin image to provide an authenticated output signal when the respective image is matched. A separator unit can separate false coins from authenticated coins.

The invention discloses a picking robot target autonomous recognition method adapted to sudden changes in illuminance, the steps are as follows: S1, calculate the optimum brightness V fit ; S2, the camera collects real-time images; S3, calculates the frame brightness V of the real-time image; S4, calculates the brightness compensation value b of the real-time image; S5, obtains the compensated image; S6, establishes the HSV model; S7, determines the target fruit. And a picking robot target autonomous recognition system adaptable to sudden changes in light intensity, including a fruit and vegetable picking robot, a controller, a camera and a light sensor are installed on the fruit and vegetable picking robot. The hood is equipped with LED lights under the camera or under the claws of the mechanical arm of the fruit and vegetable picking robot. The invention performs supplementary light processing on the image, so as to minimize the influence of light mutation and provide accurate image information for the visual system to recognize the fruit.

The present invention relates to a DICOM image blood flow analysis system. The DICOM image blood flow analysis system comprises: a DICOM file reading and playing module configured to open one or more than one DICOM files to display continuous multi-frame images; a morphology transformation module configured to perform preprocessing of the DICOM files; a blood vessel area extraction module configured to extract the main body of the blood vessel radiography based on a DBSCAN cluster algorithm and extract the fine marginal portion of the blood vessel radiography through multi-scale Gabor filtering; a blood vessel central axis extraction module configured to fuse the context information to perform blood vessel enhancement based on the extracted blood vessel area, extract a partial extreme point to act as a blood vessel central axis and remove partial spurious central axis and find out a communication component so as to complete the central axis extraction through a central axis tracking morphological method; and a calculation module configured to analyze each frame of radiography liquid expansion area and calculate the average diffusion speed and instantaneous diffusion speed of the radiography liquid. The DICOM image blood flow analysis system is able to analyze the contrast agent expansion speed in a blood vessel in real time.
