Sentence examples for image transducer from inspiring English sources

For many tasks in scientific image processing, the routine a priori correction of the image transducer properties is insufficient.

(a) Two different images collected on the same sensor (dataset of Fig. 1) can show a strong correlation of the fine image details (high frequency Fourier space components) due to a common background pattern in the image transducer.

When a large digital image dataset is available, collected with the same image transducer, then that dataset itself can be used for the statistical characterization of every pixel in the sensor.

With a reasonable a priori correction in place, the linearity of the output data, after a posteriori correction, can extend over the full dynamic range of the image transducer.

A further a posteriori correction may then also serve as a diagnostic tool to highlight new flaws arising in the image transducer or in the a priori data normalization.

This can be due to flaws of the image transducer or flaws of the flat-field correction applied, but can also be a consequence of the limited number of grey values available in the corrected image and/or of the limited time allocated for measuring the transducer characteristics.

In recent years, digital image data acquisition with image transducers like CCD/CMOS chips1 has become the standard, superseding the earlier analogue imaging technologies.

Digital image transducers contain millions of pixels, each having (slightly) different characteristics in response to identical input signals.

The scanning settings were constant for all acquired images: transducer frequency of 2 MHz, gain of 40%%, compression at 50, depth of field of 5 cm, frame rate of 39 Hz and a mechanical index of 0.1.

The success of localized ultrasonic thermal therapy depends on image guidance, typically done with a separate imaging transducer, but alignment of these transducers is challenging.

Transthoracic echocardiography was performed using a Toshiba ultrasonic image analyzing system (Nemio-XG) equipped with 7.5 MHz imaging transducer.
