US 2017/0281115 A1 · METHOD AND SYSTEM FOR TAKING MEDICAL RADIOLOGY IMAGES WITH CONTROL OF THE STOPPING OF THE X-RAY SOURCE

Abstract

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. On detection of this particular datum, the tracking device sends an electrical signal Stop-X to the radiation source, in order to stop the emission of the radiation. The system is especially suitable for taking dental radiology images with an intra-oral CMOS sensor.

A method for taking images in a medical radiology system comprising an external x-ray source and a CMOS image sensor that is connected via a USB link by way of USB peripheral of a device for digitally processing the image data of the sensor, the method comprising continuously reading and decoding the data transmitted over the USB link, in a way that is transparent to the device and to the sensor, in order to detect, in the transmitted data stream, one particular datum representing a signal indicating detection, by the sensor, that a sufficient dose of radiation has been received and, on detection of this particular datum, sending an electrical signal to the radiation source in order to stop the emission of the radiation.

A medical radiology system comprising an external x-ray source, a CMOS sensor comprising a matrix of pixels, which sensor is placed facing the source, and a device for digitally processing the images delivered by the sensor,

wherein the sensor is connected as a USB peripheral of said processing device, via a serial USB link:
the sensor is configured to detect that a sufficient dose of x-rays has been received and to transmit a corresponding particular datum over the USB link;
a tracking device is connected to the USB link, between the sensor and the device, said tracking device furthermore having an electrical connection to the source, in order to transmit at least one electrical signal to the source in order to command the stoppage of the x-ray source, said tracking device being able to detect said particular datum in the data stream transmitted over the USB link, and to activate said electrical signal commanding the stoppage of the source.
