Image Application

EDR (Exposure Data Recogniser)

The Exposure Data Recogniser (EDR) technology is a digital imaging technology and was born as a result of our long experience in the field of Computed Radiography (CR). This technology automatically adjusts the density and the contrast of images.

Non dependent on X-ray exposure level

3mA                                                                        30mA

Non dependent on Voltage level

60Kvp                                                                        120Kvp
MFP (Multi-Frequency-Processing)

The processing applicable for all types of FCR imaging, MFP is an improved version of FUJIFILM's renowned Dynamic Range Control (DRC) and frequency enhancement to provide more diagnostic information from a single exposure image. MFP improves visibility of both dense and peripheral tissues by simultaneously applying edge enhancement processing to small to large structures within an image.

FNC (Flexible Noise Control) processing

Through separation of the noise and the signal of an image, it is possible to selectively decrease the noise level. Maximum selective exclusion of unnecessary information translates into easier diagnosis.

Blackening Processing

The processing allows highlighting of specific areas of interest on the CR Console image by blackening out unneeded surrounding areas of the irradiated field of the image. (Optional)

 

Advanced Variable Response (A-VR) Spline Interpolation

FUJIFILM's A-VR automatically detects and distinguishes between image data and alphanumeric characters, ensuring clear, sharp alphanumerics even when noisy images require smooth interpolation of image data. Benefits include easier, faster, more accurate diagnosis.

 

Imaging Technology

Direct Optical Switching Technology

The X-ray sensor employs a direct switching method. The panel is comprised of a double layer of amorphous selenium. By extracting the image signal that is converted to an electric charge through our newly-developed Direct Optical Switching method rather than a TFT switch, we have reduced electronic noise and achieved a pixel pitch of 50µm.

Exposure Dynamic Range of the Imaging Plate (IP)

The amount of light emitted from the IP when exposed to X-rays is more than four times that of the conventional Screen Film System and shows a linear trend. Using this characteristic, the FCR System is able to provide a stable digital image even under varying X-ray exposure conditions.

DSR (Dual-Side Reading technology)

FCR Mammography and Paediatric systems employ revolutionary Dual-Side IP reading technology with a super fine sampling rate of 20 pixel/mm (pixel size: 50µm). This technology allows the use of IPs with a thicker phosphor on a transparent base, thereby increasing DQE (Detective Quantum Efficiency) by collecting the emissions from both sides of the IP with optimal, spatial frequency-dependent factors.

HD Linescan Technology

New “Linescan” technology was developed to make the IP image reader ever more compact and to increase its speed. This process replaces the previous point scan technology. In the sensor a new, highly sensitive, flat photostimulable phosphor “device IP” is used. This system also uses a newly developed, and highly sensitive, “wide view CCD” which can capture emissions from the device IP rapidly and efficiently. As a result the resulting unit is able to convert X-ray photons to digital data with a resolution of 100µm.

Focused Phosphor Technology

It is essential to increase the X-ray exposure efficiency to improve the image quality. To increase the efficiency, the Imaging Plate X-ray absorption has to be improved.
And to improve the Imaging Plate X-ray absorption, the phosphor layer thickness needs to be appropriately increased.

The Focused Phosphor Plate not only increased in thickness but also utilizes columnar-structured particles which act as a light guide, allowing the stimulating light to reach deep inside the phosphor layer.
The PSL (Photo Stimulated Luminescence) generated is then successfully extracted through the Focused Phosphor Plate surface. As a result, the X-ray exposure efficiency is improved.

DURATHERM™ Imaging System

FUJIFILM's innovative DURATHERM technology ensures stable, artefact-free printing performance and extended thermal-head life. Using FUJIFILM's patented micro-isolating thermal film, DRYPIX2000 produces the unexcelled image quality you have come to expect from DRYPIX imagers.

Dry Laser Imaging System

DRYPIX 4000/7000's Dry Laser Imaging System uses a photo-thermographic process, which combines laser exposure and thermal development. Following exposure to an ultra-precise laser, the photo-sensitive film is then uniformly heated using unique FUJIFILM thermal element technology. Operating costs and efficiency benefit from the elimination of wet chemicals and their environmental implications.

ECO-DRY System

DRYPIX's ECO-DRY system is environmentally friendly. DRYPIX medical films employ unique aqueous solvents that are free from unpleasant odours and create neutral coloured images so crisp, they're indistinguishable from those printed on wet halide film. Additional ECO-DRY advantages include our development of new liquid-coating technology, which minimizes the need for harmful organic solvents like methyl-ethyl ketone and toluene in the thermal development of light-sensitive materials.

ISS (Irradiation Side Sampling) method

Fujifilm's new proprietary technology “ISS method*” FPD

The “ISS method” provides highly sharp images even with low dose

The main characteristic of Fujifilm's new proprietary technology “ISS method” is the placing of the TFT sensor on the front side of the scintillation layer whereas the TFT sensor of existing panels is located on the back side. By using this new method, the scattering/reduction of X-ray signals is significantly reduced (resulting in improved MTF). Also, optimisation of the scintillation layer of the panel is achieved by Fujifilm's own precision coating technology cultivated by its vast experience in the manufacturing of Imaging Plates (IP), resulting in improved DQE.
