Product category: X-ray devices and accessories


The negatoscope is used to view medical images produced by a chain of high-tech equipment. This device, designed to read X-rays, is classified as a radiology accessory. It is nevertheless a decisive link in the quality chain. The accuracy of the radiological diagnosis and the radiologist's efficiency depend on the film reading conditions.

The negatoscope, probably due to its technical simplicity compared to the extremely complex nature of radiological equipment, is belittled in radiology departments and is not given the attention it deserves. Despite the undisputed technical progress achieved in medical imaging, the quality of the films can only be made full use of if they are read on a perfectly illuminated and homogeneous device.

Specific aspects associated with mammography

Breast X-rays are dense: therefore, a high level of luminance and perfectly homogeneous lighting are essential for reliable screening. Some micro-calcifications can only be detected with an excellent contrast and no glare.

While many manufacturers have focused on the light power,Ella Legros has chosen to concentrate on meeting new expectations expressed by radiologists, giving priority to lighting quality and homogeneity on the entire illuminated area.

The French health authorities have issued a quality control protocol for mammography installations (revised in July 1998). It is important to note that this protocol itself refers to the European protocol "European Guidelines for Quality Assurance in Mammography Screening" dated May 1996 and the DIN standard, but is more demanding in terms of homogeneity criteria.

Naturally, Ella mammoscopes dedicated to this activity comply with this protocol.


Epoxy treated 10/10 sheet steel metal box frame with anodised aluminium uprights
Straight fluorescent tubes "daylight type" light source, colour temperature 6500° Kelvin
2 manual horizontal and vertical shutters (motorised version also available). This system makes it possible to obtain a well-defined illuminated area, varying in size, at any point of the entire reading surface.
Light intensity: may vary to 7000 cd/m² depending on model
High frequency electronic ballasts. Allows light intensity regulation from 10 to 100%.
Adjustable transverse nylon wire to hold small formats in place
