TECHNOLOGY

X-rays are a form of invisible electromagnetic energy that is generated by an x-ray source. X-rays penetrate the body and the electromagnetic energy is absorbed more by dense bone and less by soft tissue. This phenomenon can be documented using a detector to show bones as white on an x ray and soft tissue as a soft blue color. There are two types of x-rays, radiography and fluoroscopy. Radiography takes a stagnant image of a structure while fluoroscopy allows the user to see the movement of dynamic biological processes in real time using a flat panel detector that converts x-rays into visible light and then digital platforms. Hybrid units that can do both radiography and fluoroscopy are fluoroscopy units that can take an image capture of the final image in a series to produce a stagnant radiography image.

 

A popular configuration for x-ray devices are C-arms that place the x-ray generator on top and the flat panel detector on bottom.

 

 

Our mobile, battery operated x-ray device, MICRO-C, is a hybrid fluoroscopy and radiography unit that is in a C-arm configuration and is designed to be used anywhere. The MICRO-C is light enough to be carried but rugged enough to be used in the field. Our device produces high quality images that can be used in the operating room, physician clinic, veterinary clinic, or in the field.

 

Our x-ray generator is a custom proprietary design using integrated radiation shielding specially developed to be lead-free, light-weight, and more rugged than conventional techniques.

Flat panel detectors are light weight and images can be transmitted in real time over long distances making them ideally suited for a mobile device. Our flat panel uses two Thallium-activated structured Cesium Iodide (CSI:TI) Scintillators to preserve good spatial resolution, a fiber optic plate to eliminate direct absorption of x-rays on the sensor’s surface, a thin high resolution scintillator to preserve the spatial resolution, and a CMOS (complementary metal oxide semiconductor) image sensor.

The CMOS image sensor uses low power consumption allowing us to make the first battery powered mobile x-ray device. With a CMOS detector, each pixel in the array is isolated from its neighboring pixels and directly connected to a transistor to have its own charge to voltage conversion from an electron hole pair that is formed in a pixel. Then, each transistor voltage is read separately and put through a column bias to correct for any under scan or over scan bias. Next, the signal is put through an analogue digital converter (ADC) and correlated doubling sampling (CDS) to allow for fast smooth read outs. Finally, the image is displayed digitally to a computer screen or smart phone. This unique set up uses low band width creating less background noise allowing for low-dose clinical images which is safer for the patient and user.

Together these components make our portable battery operated imaging device called MICRO-C rugged enough for the field and with sophisticated images for surgical settings.
