Abstract
A method for obtaining a digital chest x-ray image of a patient. The method includes providing a default set of technique settings for the chest x-ray, wherein the default set is selectable by an operator command and includes using a peak kilovoltage exposure setting that is below 90 kVp with beam filtration of the x-ray, and applying a rib contrast suppression algorithm to the digital chest x-ray image data acquired from the exposure.
Claims13
A method for obtaining a digital chest x-ray image of a patient, comprising:
- providing a default set of technique settings for acquisition of image data from an x-ray exposure of the patient's chest, the default set being selectable by an operator command and includes using a peak kilovoltage exposure setting that is below 90 kVp with beam filtration of the x-ray;
- and
- applying a rib contrast suppression algorithm to the acquired image data to generate the digital chest x-ray image.
A method for obtaining a digital chest x-ray image of a patient, comprising:
- accessing an operator instruction that specifies default settings that include exposure at a peak kilovoltage setting that is at or below 90 kVp and filtration equivalent to 0.1 mm copper;
- obtaining image data from an x-ray exposure of the patient's chest at the specified default settings;
- and
- displaying images of the obtained image data with and without rib contrast suppression processing.
A method for obtaining a digital chest x-ray image for a patient, comprising:
- providing filtration equivalent to at least 0.1 mm copper to an x-ray radiation source;
- exposing the chest of the patient with exposure from the x-ray radiation source at a peak kilovoltage setting that is at or below 90 kVp to acquire the chest x-ray image;
- displaying the acquired chest x-ray image;
- processing the acquired x-ray image using rib contrast suppression to generate a rib contrast suppressed chest x-ray image;
- and
- displaying the rib contrast suppressed chest x-ray image.
