Flat-panel digital detector D-EVO II
Thanks to its antibacterial and waterproof coating, the lightweight and durable flat-panel detector FDR D-EVO II is versatile and suitable for use in complex medical conditions. In the internal memory mode, the detector can capture images in standalone mode without connecting to the workstation. This feature allows performing processes such as computer radiography from any analog portable or stationary X-ray source. In the preview mode, it is also possible to quickly obtain images for patients with injuries even before their registration, as well as during continuous diagnostics and in case of weak wireless signal from the workstation.

High image quality and low dosage. Improved resolution and DQE of 58% for film.
Like the FDR D-EVO II, the FDR D-EVO III is equipped with an indirect conversion system called the ISS method, which binds optical sensors (TFT) to the X-ray side, unlike traditional digital flat-panel detectors. This significantly reduces scattering and attenuation of X-ray signals, creating a clear image with a low dose of X-ray radiation.

One exposure is performed in a few milliseconds, significantly reducing the possibility of patient movement compared to traditional DR radiation, which takes several seconds. The FDR D-EVO GL has approximately the same size as three standard 43.2 x 43.2 cm DR radiography detectors with a wide field of view for patients of any height and weight, without affecting the length of the obtained image.
Digital Detectors
The digital flat-panel detector (FPD) helps digitize X-ray images to obtain a clear picture. The device can integrate with both analog and digital X-ray machines, converting data into a modern convenient format. It allows for abandoning traditional wet film X-ray development, avoiding inconveniences associated with its use.
How the digital X-ray detector works
The digital detector is an electronic device housed in plastic or metal. Under the housing, there is a light-sensitive matrix (the sensitivity may vary in different models) with a protective carbon screen. Carbon is permeable to X-ray radiation, keeping the image contrast and clear. Under the influence of X-ray radiation, the sensor of the device captures and sends the obtained image directly to the matrix.
X-rays are converted into electrical signals in two ways:
- Direct (X-rays are immediately converted into a signal by photodetectors). This method is most commonly used in mammography.
- Indirect (X-rays are first converted into light and then, with the help of a photosensitive matrix, into a signal). This is applied in digital detectors.
Digital detectors are created using TFT or CMOS technology. TFT models are based on amorphous silicon photodiodes that discharge when exposed to radiation and charge when read, allowing measurement of current and image formation. CMOS technology uses semiconductor elements that charge when exposed to light and discharge when read. This approach allows for higher-quality images.
Advantages of digital detectors
FUJIFILM digital FPDs outperform analog ones in several characteristics:
- Sensitivity: Digital detectors are more sensitive than analog film, minimizing patient X-ray exposure while obtaining clearer and more detailed images of the body.
- Productivity: Significant reduction in exposure time and no need for film processing mean that an X-ray takes no more than 30 seconds. This helps increase the throughput of the X-ray room.
- Operating cost reduction: Digitization allows eliminating the purchase of developing and drying devices, film, and chemicals. There is no need to store films, freeing up valuable space in the department.
- Portability and mobility: Detectors based on digital matrices are user-friendly, easy to install, and easily transportable. They are actively used in stationary and mobile X-ray machines.
While the price of digital detectors is higher than analog ones, the aforementioned advantages significantly contribute to increased revenue.
What detector models does FUJIFILM offer
The globally renowned Japanese manufacturer FUJIFILM has developed a series of digital detectors to meet diverse diagnostic needs. These devices are mobile, compact, and durable, enabling effective operation under various conditions. They boast a high level of water and dust resistance (IPX6), preventing liquids and dust from infiltrating the device. The instruments can be used with numerous models of X-ray machines in medical facilities and beyond, allowing for examinations, even for infants in incubators. Some models can also be used with traditional films.
The extended standby mode function enables the device to remain in this mode for up to 48 hours. The innovative SmartSwitch technology automatically recognizes X-ray radiation and begins creating images. The unique ISS technology, which reads and links optical sensors to the radiation source, reduces signal attenuation, helping obtain high-quality and detailed images. The patient’s dose of X-ray radiation will be minimal. The noise suppression system helps avoid artifacts in the images.
A digital detector is capable of storing and quickly retrieving 100 or more images in memory, facilitating information processing and rapidly constructing images in emergency situations. The advanced Virtual Grid processing system ensures an optimal level of diagnostic value for each image, allowing high-quality images without the use of a coordinate grid. The Dynamic Visualization II recognition algorithms automatically adjust density and contrast.
How to Choose a Digital Detector
When selecting FUJIFILM detectors, it is recommended to consider:
- Weight
