System for assisting in the positioning of a intraoral dental radiology sensor

The invention relates to medical imaging and more particularly to intra-oral dental radiology. It proposes a radiological imaging assembly comprising an intra-oral image sensor 10, in which the sensor has an active face a corresponding to the photosensitive surface, and a mirror m1 which is placed in front of the active face of the sensor, the mirror face reflecting the visible light being turned in the same direction as the active face of the sensor, toward an x-ray source. ...

Radiation sensor with x-ray detection

The invention relates to medical imaging and, more specifically, to intraoral dental radiology. The sensor according to the invention includes a series (sphx) of detection photodiodes for detecting the arrival of an x-ray flash. ... E2v Semiconductors

Colour image sensor with white pixels and colour pixels

The invention relates to colour-image sensors. To benefit both from a good luminance resolution and a colour accuracy that is not excessively degraded by the sensitivity of silicon to near-infrared radiation, the invention proposes to produce a mosaic of pixels comprising coloured pixels (r), (g), (b), coated with colour filters, which are distributed in the matrix, with white pixels (t) not coated with colour filters and which are distributed in the matrix. ...

Active pixel image sensor based on cmos technology with electron multiplication

In an active pixel image sensor using cmos technology formed within a substrate of a first type of conductivity p, each pixel comprises a photosensitive element phd producing charges under the effect of light and a structure for multiplication of charges em. The multiplication structure comprises at least one isolated multiplication gate g1, g2 adjacent to a pinned diode di at a fixed internal potential vbi, and the isolated gate is adapted for receiving a series of alternations of potentials, alternately creating under the isolated gate a charge collection well and a barrier, relative to the internal potential level of the diode di. ...

Method for synchronously distributing a digital signal over n identical adjacent blocks of an integrated circuit

The invention proposes a method for distributing a signal to each block bj of a series of n adjacent blocks of identical design in an electronic circuit. It proposes, in an identical fashion for each of the n blocks, placing a timing delay circuit mux-delj on the path for conveying a signal sc from the input incj of the block to an internal electrical node ndj of the block for this signal sc; providing for the timing delay circuit to supply n delayed signals corresponding to n different timing delays Δf1 , . ...

Method and system for taking medical radiology images with control of the stopping of the x-ray source

A medical radiology system comprises an external x-ray source (1) and a cmos image sensor (2) that is connected via a usb link (4) by way of usb peripheral of a device (3) for digitally processing the image data of the sensor. A tracking device is placed on the usb link (4) in order to continuously read and decode the data transmitted over this link in a way that is transparent to the device and to the sensor, and to detect, in the transmitted data stream, one particular datum (xamc=1) representing a signal indicating detection, by the sensor, that a sufficient dose of radiation has been received. ...

Time delay integration image capture method correcting image defects caused by cosmic particles

To eliminate image defects produced by high-energy particles passing through a time delay integration image sensor, upstream detection is effected on the digital values supplied by the pixels of the same rank that have successively observed the same scene point. This detection makes it possible to ignore or to correct values from corrupted pixels in establishing the digital signal representing the luminance of an observed scene point. ... E2v Semiconductors

Method for capturing an image with dark current reduction and low power consumption

The invention relates to a method for capturing an image in an image sensor with a matrix of rows and columns of active pixels, powered between a first power supply terminal at zero potential (vss) and a second power supply terminal at a positive power supply potential (vdd). Each pixel comprises a photodiode and a gate for transferring the photogenerated charges to a charge storage node. ... E2v Semiconductors
