摘要： Methods and systems are provided for automatic exposure control in computed tomography imaging systems. In one embodiment, a method comprises in response to an object-specific dose metric input by a user via a user interface operably coupled to a scanner, predicting an image quality of a diagnostic scan, calculating an output level of a source of the scanner for the image quality, and performing the diagnostic scan at the output level when the image quality is higher than a threshold. In this way, patient-specific image quality settings may be determined.

摘要： A computer-implemented method for generating and simulating a computed tomography (CT) protocol is provided. The method includes receiving, via a graphical user interface, at a processor user input including patient population size settings and scan technique settings for modeling the effects of the scan technique settings across a patient population as a function of patient size. The method also includes generating, via the processor, a patient population profile based on at least the patient population size settings and the scan technique settings, wherein the patient population profile includes specific CT scan technique settings to be applied across different size ranges of the patient population as a function of patient size. The method further includes displaying, on the graphical user interface, one or more visualization elements illustrating the effect of these specific CT scan technique settings on specific imaging metrics across the patient population.

摘要： Methods and systems are provided for automated tube current modulation (ATCM). In one embodiment, a method for an imaging system comprises: calculating a desired dose level based on a clinical task, a size of a subject to be scanned, and an image quality level; generating a scan protocol based on a relation between the image quality level and at least one characteristic of the imaging system; and performing a scan of the subject at the desired dose level and according to the generated scan protocol. In this way, ATCM can be optimized based on elements that impact image quality such as the clinical task, the physical characteristics of the imaging system, the individual patient, and the reader's preference.

摘要： An imaging system is provided including a selectable pre-object filter module, a detector, and a processing unit. The selectable pre-object filter module is configured to absorb radiation from the X-ray source to control distribution of X-rays passed to an object to be imaged. The selectable pre-object filter module has plural pre-object filter configurations providing corresponding X-ray distributions, and is selectable between the plural configurations to provide a selected pre-object filter configuration for a scan of the object. The detector is configured to receive X-rays that have passed through the object. The processing unit is operably coupled to the selectable pre-object filter module and the detector, and is configured to identify an anatomy to be imaged, determine a corresponding image quality and radiation dose for each of the plural pre-object filter configurations; and select the selected pre-object filter configuration based upon the determined corresponding image qualities and radiation doses.

摘要： Methods and systems are provided for adjusting medical imaging parameters based on imaging parameters used during a previous imaging session. In one embodiment, a method for a computed tomography (CT) system includes reducing a radiation level of at least one CT scan of one or more successive CT scans performed on a patient based on CT scan information obtained from a previous CT scan performed on the patient, the radiation level reduced relative to a radiation level of the previous CT scan.

摘要： Methods and systems are provided for profile-based selection of imaging parameters for a clinical context. In one embodiment, a method comprises selecting a profile based on an indication of clinical context for a scan of a patient, selecting one or more sub-profiles based on the profile, selecting imaging settings for the scan based on the profile and the one or more sub-profiles, and performing the scan according to the selected imaging settings. In this way, a scan prescription may be defined more efficiently and personally for a patient while improving quality assurance and managing an x-ray radiation dose of the patient.

摘要： An imaging system is provided including an adjustable source collimator, an input unit, and a processing unit. The adjustable source collimator is configured to be interposed between an X-ray source and an object to be imaged, and is adjustable between plural settings corresponding to different amounts of collimation of rays from the X-ray source. The input unit is configured to obtain an input identifying a portion to be imaged of the object. The processing unit is operably coupled to the input unit and the adjustable source collimator, and configured to obtain the input. The processing unit is also configured to determine a prescribed collimation configuration to perform a scan of the portion to be imaged based on the input, the prescribed collimation configuration having a corresponding scanning volume that includes the portion to be imaged.
