Abstract: A computer readable storage medium having a computer program stored thereon and representing a set of instructions that when executed by a computer causes the computer to calculate a mapping function that provides a location of each sub-volume of an imaging volume as a function of time from ultrasound data and determine a respective acquisition window for each sub-volume of the imaging volume from the mapping function. The instructions also cause the computer to reconstruct an image of the imaging volume substantially free of motion artifacts from imaging data acquired from the imaging volume.

Abstract: Motion data is acquired simultaneously and in real-time with image data. The motion data provides accurate and near-instant information as to the state and position of an object prone to motion. The present invention is particularly applicable for cardiac CT or MR imaging and other physiologically gated acquisitions. In the context of cardiac imaging, the motion data includes information regarding size and location of the heart during the cardiac phases (diastole, systole, etc.) during each cardiac cycle.

Abstract: An ultrasound apparatus includes an ultrasound probe and a probe positioning device operably connected to the ultrasound probe. The probe positioning device is configured to provide one of an orientation and a position of the ultrasound probe during ultrasound imaging.

Abstract: A wearable ultrasound probe apparatus includes a wearable membrane. An ultrasound transducer is also included that is integrated into the wearable membrane and configured to maintain a substantially consistent contact with a surface of an object to be imaged when the object has the wearable membrane disposed thereon.

Abstract: A brightness detector is used to control the x-ray exposure and the displayed image level in a diagnostic x-ray imaging system. Initially, a region of interest of an image is specified. The average pixel value within the specified region of interest of the image is then found, ignoring regions below a preselected low signal level threshold. Finally, the average pixel value is fed back to the x-ray generator to control the x-ray exposure. The average pixel value is also used to determine a scaling factor to be applied to the image in order to maintain an optimum brightness level when the desired x-ray exposure cannot be attained.

Abstract: Offset signals are removed from an incoming x-ray image produced by a large area solid state x-ray detector. A sequence of incoming dark images from the detector, when the detector is not exposed to x-rays, is recursively filtered to generate a low-noise, continuously-updated offset image. This low-noise continuously-updated offset image is stored in an offset image memory. The image in memory is subtracted from the incoming x-ray image to create a corrected image when the detector is exposed to x-rays.
