摘要:
An injection system (500) comprising: an injection device (502); an operator interface (507), configured to receive inputs from an operator of said injection system; a module for determining the target concentration of contrast agent in blood flow (508), configured to: receive an input of the type of contrast agent; receiving a first image capture parameter of an Magnetic Resonance Angiography, ARM, image sensor to be used in an ARM image capture procedure; and calculating an objective concentration of contrast agent in the blood flow (607) based at least partially on the input of the type of contrast agent received and the first image capture parameter received; the injection system (500) further comprising a module for determining the rate of injection of contrast agent (509), configured to: receive the target concentration of contrast agent in the calculated blood flow (607); receive an initial contrast agent concentration input; receive a cardiac output rate entry from a patient whose image is to be captured; and calculating a contrast agent injection rate (608) based at least partially on the target concentration of contrast agent in the blood flow (607), the initial contrast agent concentration input received, and the input rate of cardiac output received.Un sistema de inyección (500) que comprende: un dispositivo de inyección (502); una interfaz de operador (507), configurada para recibir entradas desde un operador de dicho sistema de inyección; un módulo de determinación de la concentración objetivo de agente de contraste en el flujo sanguíneo (508), configurado para: recibir una entrada del tipo de agente de contraste; recibir un primer parámetro de captación de imagen de una Angiografía por Resonancia Magnética, ARM, captador de imagen a ser usado en un procedimiento de captación de imagen de ARM; y calcular una concentración objetivo de agente de contraste en el flujo sanguíneo (607) basándose al menos parcialmente en la entrada de tipo de agente de contr
