Endoscopic imaging with augmented parallax
11357593 · 2022-06-14 · ·

A method for imaging involves scanning an anatomical object within a patient and capturing reflected IR light with a plurality of cameras that are separate from the scanner. The IR images captured by the IR cameras are associated together to create an integrated image based on parallax between the IR cameras and the scanner. The integrated image is associated with a separate or optical light image of the anatomical object to generate an intra-operative 3D image that can be created in real-time. Systems for effectuating such imaging may include multiple surgical instruments supporting various cameras positioned to capture different fields of view and to increase parallax.

Multi-pass computed tomography scans for improved workflow and performance
11357467 · 2022-06-14 · ·

An x-ray imaging apparatus and associated methods are provided to execute multi-pass imaging scans for improved quality and workflow. An imaging scan can be segmented into multiple passes that are faster than the full imaging scan. Data received by an initial scan pass can be utilized early in the workflow and of sufficient quality for treatment setup, including while the another scan pass is executed to generate data needed for higher quality images, which may be needed for treatment planning. In one embodiment, a data acquisition and reconstruction technique is used when the detector is offset in the channel and/or axial direction for a large FOV during multiple passes.

Sorting biological and non-biological moieties using magnetic levitation

Systems and methods for levitating populations of moieties, cells, or other such units using one or more magnets in a microfluidic environment are provided.

A system for facilitating identification and marking of a target in a fluoroscopic image of a body region of a patient, the system comprising one or more storage devices having stored thereon instructions for: receiving a CT scan and a fluoroscopic 3D reconstruction of the body region of the patient, wherein the CT scan includes a marking of the target; and generating at least one virtual fluoroscopy image based on the CT scan of the patient, wherein the virtual fluoroscopy image includes the target and the marking of the target, at least one hardware processor configured to execute these instructions, and a display configured to display to a user the virtual fluoroscopy image and the fluoroscopic 3D reconstruction.

Correlation of multiple-source image data

Compositing is provided in which visual elements from different sources, including live action objects and computer graphic (CG) merged in a constant feed. Representative output images are produced during a live action shoot. The compositing system uses supplementary data, such as depth data of the live action objects for integration with CG items and light marker detection data for device calibration and performance capture. Varying capture times (e.g., exposure times) and processing times are tracked to align with corresponding incoming images and data.

Asymmetric scatter fitting for optimal panel readout in cone-beam computed tomography

An x-ray imaging apparatus and associated methods are provided to receive measured projection data in a primary region and measured scatter data in asymmetrical shadow regions and determine an estimated scatter in the primary region based on the measured scatter data in the shadow region(s). The asymmetric shadow regions can be controlled by adjusting the position of the beam aperture center on the readout area of the detector. Penumbra data may also be used to estimate scatter in the primary region.

Systems and methods for image reconstruction

A method may include obtaining a first acquisition time period related to a scan of a first modality performed on an object. The method may also include obtaining one or more second acquisition time periods related to a scan of a second modality performed on the object. The method may also include obtaining, based on the first acquisition time period and the one or more second acquisition time periods, target data of the object acquired in the scan of the first modality. The method may also include generating one or more target images of the object based on the target data.

20220139004 · 2022-05-05 ·

A method for photoacoustic imaging is performed by measuring RF time samples from transducer elements, and reconstructing an estimated initial pressure image from the measured RF time samples and a pre-calculated forward model matrix. The reconstructing involves minimizing the difference between the pre-calculated forward model matrix applied to the image estimate and the measured RF time samples by implementing a superiorized modified conjugate gradient least squares algorithm to minimize the total variation norm. The model matrix factors each of the transducer elements into sub-wavelength mathematical elements.
