    Abstract: PROBLEM TO BE SOLVED: To provide methods for adjusting injection protocols with respect to each individual patient.SOLUTION: A step is included for specifying a patient transfer function based on data specific to the patient, wherein the patient transfer function predicts enhancement at desired level, which is output from one or more regions of interest in an individual patient, in response to a predetermined input. A step is included in which, when a fluid containing a contrast-enhancing fluid is diffused, by using scanning data obtained by test-scanning the one or more regions of interest, the output of the enhancement level due to the diffusion of the fluid is determined in synchronization at a plurality of points from each of the one or more regions of interest. By using at least several operation data obtained through the test scanning, the patient transfer function is updated, and a predetermined input is determined through a numerical optimization technique. Injection protocols for individual patient is determined when the predetermined input is input in the patient transfer function, thereby generating the enhancement at desired level in the one or more regions of interest. It is preferable that the injection protocols are managed in relation to diagnostic imaging procedure.

    Abstract: PROBLEM TO BE SOLVED: To measure a radioactive agent using a detector system.SOLUTION: A fluid path receives at least one aliquot of a radiopharmaceutical. The fluid path locates the aliquot within a positioner formed to have a concave configuration. A detector is located at a certain axial distance from the concave surface and determines the level of radioactivity of the aliquot. Alternatively, the fluid path may be free of concave and a variable attenuator may be placed between the fluid path and the detector. The variable attenuator may have a concavity that is based on the concavity of the fluid path so that the detector's ability to read the radioactivity is optimized. A method for forming an aliquot of a radiopharmaceutical in a concave fluid passage includes arranging a detector to a position separated from the concave surface by a certain distance to optimize reading of spectral energy emitted from the aliquot and activity and determine radioactivity regardless of the position of the aliquot in the passage.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for determining a parameter for a contrast medium injection protocol to be performed on a patient.SOLUTION: A model is provided that describes the diffusion of a fluid from the injected point of the fluid to the patient's pulmonary artery region and ascending aorta region. The model makes it possible to predict that an output of a predetermined enhancement level will be made from the regions, and determines a physiological variable value regarding to the patient's cardiopulmonary function when into the model are input one discrete data point obtained from a first time enhancement curve associated with the pulmonary artery region and one discrete data point obtained from a second time enhancement curve associated with the ascending aorta region. Each of the discrete data points represents a pair of measured values on the time enhancement curve corresponding to the associated region. In addition, when a parameter for the injection protocol is determined by applying the physiological parameter to the model, a desired level of enhancement output from the pulmonary artery region and the ascending aorta region is thereby caused during a diagnostic imaging on the patient.

Preamplifier, power splitting and combining networks within the interface device process voltage signals of the MR signal and enable them to be conveyed to the input port(s) of the MR system.
