1” High Resolution Resistron® –
Camera Tube
XQ 1395
For use in medical TV application
Antimonytrisulfide – photoconductive layer (Sb2S3)
Separate mesh connection (grid-4-electrode)
Description
Camera Tubes are the key component of
High Performance X-ray TV systems in
medical applications. Their high
sensitivity and high dynamic range
combined with high resolution allows
real-time x-ray imaging for any type of
medical imaging as during critical
surgeries. The Resistron® camera tube
XQ 1395 is a 1” diameter image tube with
magnetic focusing and magnetic
deflection method for camera installations
adapted through optics to X-ray image
intensifiers.
Features and Benefits
High sensitivity
Video high-resolution
High dynamic range
Real-time X-ray imaging
Low noise imaging
Applications
Radiography
Cardiology
C-arm
Angiography
Radiosurgery

Blemish Specification
- Test Conditions
The tube shall be centred and focused according to the operating and adjusting instructions for
optimum performance.
Illumination should be adjusted to a signal current of 250 nA at a beam current for stabilising a
signal of 500 nA.
- Target Zone
A uniformly illuminated field with an aspect ratio of 3:4 and a scanned area of 15.0 mm x 20.0 mm
shall be displayed on the target of the camera tube. According to the following drawing the scanned
area is divided into three zones 1, 2 and 3.
The blemish size is measured in percent of the picture height. The equivalent numbers of TV-lines
are indicated for comparison purposes only. Black and white spots are equally weighted.
Measurement of blemishes will be performed with and without target illumination. The minimum
separation between two target spots must be greater than the diameter of the larger one, otherwise
the combination is considered as a whole. Target spots with a diameter ≤ 0.2 % of the picture height
as well as blemishes with a modulation depth ≤ 10 % are not counted, unless an accumulation
causes a smudged appearance.
Blurred spots, streaks, stripes, mesh defects and mottled or grainy background are only permitted
up to a noise amplitude of 10 %.
