Abstract
A wireless intraoral dental x-ray imaging sensor and method of use. The sensor optionally has a rechargeable battery located away from the edge of a PCB/ceramic substrate to enable encapsulation. The sensor has a compact microcontroller unit with several blocks including a radiolink, processing capacity, and a low power management system. Bit truncation and image compression take place on a readout substrate and/or on the MCU. External memory blocks allow for at least partial image storage for safety and as a backup.
Claims19
A wireless intraoral x-ray imaging sensor, comprising:
- a radiation sensitive detector configured to detect impinging x-rays and create an output signal;
- a plurality of pixels on a readout substrate, the plurality of pixels configured to receive said output signal from the radiation sensitive detector, said readout substrate configured to output x-ray image data in the form of analog or digital pixel values;
- and
- an additional substrate connected to said readout substrate, the additional substrate comprising
- electronics configured to create a wireless link and to transmit said x-ray image data to a receiver, and
- a rechargeable battery configured to provide power to said wireless intraoral x-ray imaging sensor, said rechargeable battery comprising edges that have a minimum distance of 2 mm from the edges of said additional substrate.
