Abstract
A method of imaging by means of ionizing radiation in which a first measurement f1 is performed by integrating a detection signal generated by each detection cell of an ionizing radiation detector while simultaneously making a second measurement f2 by counting ionizing rays, and then an estimate of the flux is calculated, in particular by using the formulaf=&agr;·f1+(1−&agr;)·f2where &agr; is an increasing function over the range 0 to 1 of a first estimate fe of the flux f, which first estimate is established as a function of at least one of the first and second measurements f1 and f2.
