Title (EN) METHOD AND DEVICE FOR DETERMINING A SPECTRAL COMPUTED TOMOGRAPHY SCAN PROTOCOL
(FR) PROCÉDÉ ET DISPOSITIF DE DÉTERMINATION D'UN PROTOCOLE DE BALAYAGE SPECTRAL DE TOMODENSITOMÉTRIE
Abstract:
(EN) The present invention relates to a method (500) for determining a spectral scan protocol for acquiring a computed tomography (CT) image using a CT scanner and a corresponding apparatus (600). The method (500) comprises the steps of defining (510) a conventional scan protocol having scan restrictions for acquiring a conventional CT image; determining (520) a spectral scan protocol comprising a proportion of a first acquisition mode (201) and a proportion of a second acquisition mode (202), wherein the spectral scan protocol resembles the conventional scan protocol; and determining (520) the proportion of the first acquisition mode (201) and the proportion of the second acquisition mode (202) so that the scan restrictions of the conventional scan protocol are met. The method (500) and corresponding apparatus allows the determination of spectral scan protocols which reduce spectral scan mode restrictions.
(FR) La présente invention concerne un procédé (500) pour déterminer un protocole de balayage spectral pour acquérir une image de tomodensitométrie (CT) à l'aide d'un scanner CT et un appareil (600) correspondant. Le procédé (500) comprend les étapes consistant à définir (510) un protocole de balayage classique ayant des restrictions de balayage pour acquérir une image CT classique; à déterminer (520) un protocole de balayage spectral comprenant une proportion d'un premier mode d'acquisition (201) et d'une proportion d'un second mode d'acquisition (202), le protocole de balayage spectral ressemblant au protocole de balayage classique; et à déterminer (520) la proportion du premier mode d'acquisition (201) et la proportion du second mode d'acquisition (202) de telle sorte que les restrictions de balayage du protocole de balayage classique sont satisfaites. Le procédé (500) et l'appareil correspondant permettent la détermination de protocoles de balayage spectral qui réduisent les restrictions de mode de balayage spectral.
