Method for acquiring measurements and scanner implementing said method

Abstract

In order to solve an analogue/digital conversion dynamic swing problem encountered with detectors, especially solid-state detectors, of a tomodensitometer, there is provision to operate converters at a greater frequency, that is to say more often. In doing this, the converters used need not have as large a conversion dynamic swing. It is shown that instead of a 20-bit conversion, one can make do with a 14-bit conversion. The various conversions are added together to construct the signal. The measurement is thereafter switched, by way of improvement, as a function of the level of the signal received. This measurement is performed according to one mode of use or another, in which modes this acceleration of the rate of analogue/digital conversion is or is not effected.
