The present invention provides catheter apparatus and catheterization methodology for generating an arteriovenous fistula or a veno-venous fistula on-demand between closely associated blood vessels and at a chosen anatomic site in-vivo. The catheter apparatus is preferably employed in pairs, each catheter of the pair being suitable for percutaneous introduction into and extension through a blood vessel. The catheterization methodology employs the catheter apparatus preferably in conjunction with conventional radiological techniques in order to place, verify, and confirm a proper alignment, orientation, and positioning for the catheters in-vivo prior to activating the perforation means for generating a fistula. The invention permits the generation of arteriovenous fistulae and veno-venous fistulae anatomically anywhere in the vascular system of a patient; nevertheless, the invention is most desirably employed in the peripheral vascular system as exists in the extremities of the body to aid in the treatment of the patient under a variety of different medical ailments and pathologies.

Apparatus, systems, and methods to improve imaging quality control, image processing, identification of findings, and generation of notification at or near a point of care are disclosed and described. An example imaging apparatus includes a processor to at least: evaluate first image data with respect to an image quality measure; when the first image data satisfies the image quality measure, process the first image data using a trained learning network to generate a first analysis of the first image data; identify a clinical finding in the first image data based on the first analysis; compare the first analysis to a second analysis, the second analysis generated from second image data obtained in a second image acquisition; and, when comparing identifies a change between the first analysis and the second analysis, trigger a notification at the imaging apparatus regarding the clinical finding to prompt a responsive action.

A surgical radiological C-arm imaging unit drape configured to provide a sterile outer surface about an end portion of a C-arm imaging unit and method of providing a sterile surface about an end of a C-arm imaging unit is provided. The drape includes a flexible enclosure having an upper wall with a pair of sidewalls and a rear side extending downwardly from the upper wall. The upper wall and the side walls are extendible between expanded and collapsed positions. When in the expanded position, a pocket sized for receipt of the end portion of the imaging unit beneath the upper wall is formed. The upper wall has a sterile outer surface configured to face away from and overlie the end portion of the imaging unit to maintain sterility in a sterile zone above an operating table. When in the collapsed position, the sterile outer surface shielded from external contamination.

Embodiment methods of treating a human or animal patient using a remotely controlled robotic catheter device inserting a handle of a catheter into a handle controller, inserting the catheter tubular portion into a resealable delivery channel forming a sterile barrier to a sled base, engaging a tip of the catheter with a sterile introducer disposed at an end of the sled base and engaged with the patient's body, positioning the catheter into the patient's body by remotely sending commands to the tele-robotic device to cause the sled member to advance toward the patient's body, and performing a diagnostic or therapeutic procedure on the patient using the catheter. Diagnostic or therapeutic procedures may include a mapping procedure, an ablation procedure, an angioplasty procedure, a drug delivery procedure; an electrophysiology procedure, a radiological procedure, and a medical device implantation or positioning procedure.

An x-ray device comprises means for the production of at least one standard projection image of the object in which presumed suspect zones corresponding to radiological signs are represented by markers. The device comprises means for the production of a digital volume of markers in which 3D markers are created in order to represent presumed suspect zones of the object. It also comprises means of re-projection of the 3D markers in the standard projection image in order to confirm the presence of the markers or eliminate or add the markers of the projection image is necessary.

A CT- or MRT-assisted image acquisition, image archiving and image rendering system allows generation, storage, post-processing, retrieval and graphical visualization of computed or magnetic resonance tomography image data that, for example, can be used in the clinical field in the framework of radiological slice image diagnostics as well as in the framework of interventional radiology. Moreover, a method implemented by this system allows reproduction of patient-specific examination parameters of an initial examination implemented by means of computed or magnetic resonance tomography imaging in the framework of CT or MRT follow-up examinations (“follow-ups”), for example in a post-operative tumor examination implemented under slice image monitoring in connection with a histological tissue sample extraction (biopsy) implemented under local anesthesia or a minimally-invasive intervention implemented for tumor treatment. Acquisition, measurement, 2D and / or 3D reconstruction parameters from a radiological initial examination of the patient conducted by means of CT, PET-CT or MRT as well as position data to establish the position adopted by this patient on the examination table of a computed tomography or magnetic resonance tomography apparatus are electronically documented, retrievably and persistently stored, and are automatically reused given subsequent CT-, PET-CT- or MRT-based monitoring examinations, or CT-controlled or MRT-controlled interventional or operative procedures.

A teleradiology image processing system configured to receive, process, and transmit radiology read requests and digital radiology image data is disclosed herein. In one embodiment, a radiology processing system includes a series of processing components configured to receive digital radiology data from a medical provider, extract relevant information and radiology scan images from the digital radiology data, and initiate and control a workflow with a qualified remote radiologist who ultimately performs a read of the radiology scan images. Further embodiments also facilitate data processing within the image processing system in response to medical facility rules and preferences; translation or conversion of digital images to other formats; compilation of patient and medical facility data obtained from the digital radiology data into medical records or data stores; assignment of radiology studies within a teleradiology workflow in response to licensing and credentialing rules; and billing functions in response to completed reads by the remote radiologist.

In a method for the obtaining a tomosynthesis image for a more selective detection of radiology signs, a dose distribution strategy is proposed. The strategy is defined as a function of a substantially uniform depth-of-focus for a variety of sizes and classes of radiology signs. This strategy is coupled with a digital filtering aimed at ensuring optimum propagation of the signal-to-noise ratio beyond the frequency spectrum. This digital filtering is done by means of a class of adaptive filters required to control the propagation of the noise during the reconstruction. The filter to be applied to each projection of the X-ray tube (4) depends on the dose assigned to this projection.

A system for guiding a user's physical examination of a patient and for generating a transcript. The system comprises: a screen requesting patient identification information, wherein the patient identification information excludes a patient name and further requesting patient medical history information; a screen requesting vital signs information; a screen requesting selection of an anatomical region of the patient for examination, wherein the user selects an anatomical region responsive to the request; a screen providing a plurality of possible observed symptoms related to the selected anatomical region, wherein the user selects one or more of the possible observed symptoms; a screen presenting possible findings that may be observed during the physical examination, wherein the user selects one or more of the possible findings based on the physical examination and a screen displaying a patient transcript responsive to information entered into the previous screens
