Modules, systems and methods for clearing substances from a living body are disclosed. A module may include an instructions receiver configured to receive wireless transmissions of instructions from a master controller located outside of the body when the module is inside the body; an energy receiver configured to receive wireless transmission of non-destructive energy from the master controller located outside of the body when the module is inside the body; an energy converter configured to convert the non-destructive energy received to destructive energy; and an energy emitter configured to emit the destructive energy.

A system includes a processor circuit that receives physiology measurements obtained by an intraluminal physiology measurement device within a body lumen. The processor circuit automatically segments the body lumen into a plurality of segments based on the physiology measurements. The processor circuit then determines a change in the physiology measurements corresponding to each segment and determines a recommended position for a treatment device within the body lumen based on the change for each segment. The processor circuit provides an output associated with the recommended position on a display.

A system includes a processor circuit that receives intravascular imaging data from an intravascular imaging catheter, an x-ray image from an x-ray imaging device, and intravascular pressure data from an intravascular pressure-sensing guidewire. The processor circuit correlates the intravascular imaging data and the intravascular pressure data to locations along a body lumen shown in the x-ray image. The processor circuit generates a longitudinal view of the body lumen based on the intravascular imaging data and outputs a screen display including the longitudinal view of the body lumen with an overlaid graphical representation corresponding to the intravascular pressure measurements.

An imaging system for imaging an object, the imaging system comprising: a housing having a center opening; a CT imaging unit mounted to the housing, the CT imaging unit comprising: a rotatable disc extending around the center opening; an X-ray emitter mounted to the rotatable disc and configured to emit an X-ray beam; and an X-ray detector mounted to the rotatable disc in alignment with the X-ray beam; and a digital radiography imager comprising a detector plate mounted to the rotatable disc, the detector plate being configured to assume (i) a retracted position in which the detector plate is not aligned with the X-ray beam, whereby to permit the X-ray beam to contact the X-ray detector, and (ii) an extended position in which the detector plate is aligned with the X-ray beam, whereby to permit the X-ray beam to contact the detector plate.

The invention describes a method of performing intra-operative navigation during a surgical procedure, which method comprises the steps of arranging a video imaging device on a radioscopic imaging apparatus; obtaining an initial radioscopic image of a target and identifying a desired trajectory in a target; determining a first position of the radioscopic imaging apparatus relative to the target for which a central image axis of a radioscopic imaging unit is aligned with the desired trajectory; positioning the radioscopic imaging apparatus to align a central image axis of the video imaging device with the desired trajectory; and showing a live video feed of the surgical procedure on a monitor to track the position of a surgical implement relative to the desired trajectory.

A medical diagnostic method, system and related equipment particularly adapted to diagnose disorders of the blood circulation serving the head and neck, and especially the brain. A preferred use of the system is early, rapid, accurate, diagnosis of stroke, especially whether the stroke is due to blockage of a blood vessel or leakage from the blood vessel.

A structure extracting unit extracts a structure from a three-dimensional medical image, and a view point determining unit determines a view point position and a direction of line of sight of a virtual endoscopic image. An image generating unit calculates a distance between a view point position and the extracted structure, determines a display attribute of the extracted structure based on the distance and a plurality of different display attributes that correspond to different distances from the view point position and are defined for each of the structures, and generates, from the three-dimensional medical image, a virtual endoscopic image containing the structure having the determined display attribute. A display control unit displays the thus generated virtual endoscopic image on a WS display.

The present disclosure provides a system and method for motion field generation and image correction. The method may include obtaining a plurality of first sets of magnetic resonance (MR) image data of an object generated based on a plurality of first sets of imaging sequences. The method may include obtaining a motion curve of the object. The method may include obtaining position emission tomography (PET) image data of the object generated in a scanning time period. The method may include generating one or more target motion fields corresponding to the scanning time period based on the plurality of first sets of MR image data and the motion curve. The method may include generating one or more corrected PET images by correcting, based on the one or more target motion fields, the PET image data.

A noninvasive system for imaging, planning, and treating cardiac arrhythmia in a subject includes a noninvasive means for imaging a heart and identifying an arrhythmia including an array of body surface electrodes for noninvasively measuring electrical potentials at a plurality of locations to identify the arrhythmia, and a geometry determining device for noninvasively obtaining a heart-torso geometry. An imaging processor computes heart electrical activity data and generates an image of the heart from the electrical potentials and the heart-torso geometry. A treatment planning system for developing a noninvasive treatment plan for the arrhythmia is configured to import an arrhythmia target defined relative to the image of the heart, and register the imported arrhythmia target to a primary planning dataset. A noninvasive means for treating the arrhythmia includes implementing the noninvasive treatment plan developed by the treatment planning system.

A probe device for detecting atherosclerotic plaque may include: an elongate shaft having a proximal end for coupling with a catheter and a distal end; an opening in a side of the shaft; a scintillating window disposed over the opening to form a water tight seal and thus form an imaging window compartment; a 45-degree rotating mirror disposed at least partially within the imaging window compartment; and an ultrasound transducer disposed at least partially within the imaging window compartment. The probe is a dual-modality, catheter radionuclide imaging and photoacoustic tomography (CRI-PAT) probe.
