    摘要: An injection system includes an injector for injecting a fluid into a patient and a controller in operative communication with the injector for control thereof. The controller controls a diagnostic injection of the fluid based upon at least one mathematical model individualized to the patient. The model(s) are determined by collecting data corresponding to a time response curve resulting from at least one test injection of the fluid into the patient. The time response curve represents a response of a region of interest of the patient over time due to the fluid passing therethrough. An imaging system having such an injection system is also disclosed, as is a system for effecting a medical procedure. A method of delivering such a fluid to a patient using such an injection system is also disclosed, as is a method of modeling propagation of such a fluid in a patient.

    摘要: A method of controlling an injector system for delivering a contrast enhancing fluid to a patient. The method includes the step of determining at least one patient transfer function for the patient based upon data specific to the patient, with the at least one patient transfer function providing a time enhancement output for a given input. The data specific to the patent may include at least one of an estimate of physiologic parameters of the patient, an estimate of anatomic parameters of the patient and an enhancement caused by an injection of the contrast enhancing fluid into the patient. Other steps involve: determining a desired time enhancement output; using the at least one patient transfer function to determine an injection procedure input; and controlling the injector system at least in part on the basis of the determined injection procedure input.

    摘要: A method for injection of an imaging contrast into a patient, includes: a. in a first phase, injecting a fluid having a first concentration of contrast agent for a first period of time; and b. in a second phase, injecting a fluid having a second concentration of contrast agent for a second period of time. The osmolarity of the second phase is higher than the osmolarity of the first phase. The method can further include: c. in a third phase, subsequent to the second phase, injecting a fluid having a third concentration of contrast agent for a third period of time. The osmolarity of the third phase is lower than the osmolarity of the second phase. In embodiments in which the composition of the contrast agent of the third phase is the same as the composition of the contrast agent of the second phase, the third concentration can be lower than the second concentration.
