IMAGE QUALITY


Image quality is of course the central point of comparison in Digital Radiography.

The 1st rule to get good images is to have a good hardware adapted to the application. Traditional parameters such as kV, mA, focal spot size, SDD, SOD (for the blur, the distorsion or the optical magnification) are still important. In Digital Radiography, other ones such as panel technology (@Si, @Se, CMOS, ...), pixel size, scintillator material, scintillator thickness, sensitivity, integration time, ... are to be taken into account.

According to your application, X-RIS can supply you the right material and advise you the appropriate radiography technique.

What makes our offer outstanding, is the easyness with which you will achieve your work. The challenge is not to get good images... The challenges are that the users of digital systems can get the best image by themselves and to make this complex technology user-friendly.

In this perspective and in combination with our hardware solutions, we have developed Maestro software.
After 2 hours training you will master your new digital tool and get best of it.



IMAGE GALLERY



This picture was taken with :
- GXC-225 at 160 kV - 3 mA - 60 s - 70 cm - FS: 1 mm x 1 mm [ASTM E 1165]
- Dereo HE : @Si - GadOx DRZ fine - pixel 140 µm - D9 [ISO 19232-5] - SNR > 1000.

Before any image treatment image quality is already excellent due to the performances of the DR.
The contrast filter permits to resolve W17 (80 µm - 3.1 mils), 4 more wires than required by class B [ISO 17636-2] !


Fig.1 - Base image supplied by GXC and Dereo.
Note that exposure charts specify 160 kV - 4 mA - 5 min with D4 film at 70 cm, ie 6.5 times more dose for a film than for the DR here.

Fig.2 - X-RIS contrast filter - W17 [80 µm - 0.0031"] is resolved -> 0.65 % of contrast.
