A controller for displaying a puncture site of an intra-atrial septum for heart repairs includes a memory and a processor (). The processor () executes instructions () to perform a process based on image data of a heart that includes a mitral valve and an intra-atrial septum. The process includes defining a mitral valve annulus plane along a mitral valve annulus of the mitral valve and a normal vector perpendicular to the mitral valve annulus plane. The process also includes defining an offset plane that intersects with the intra-atrial septum and that is parallel to the mitral valve annulus plane. A safe zone for the puncture site is identified and displayed on the intra-atrial septum. The safe zone is between a lower boundary plane () and an upper boundary plane () that are each parallel to the offset plane by specified distances.

Trans-septal puncture guidance heart repair

A method for determining an optimal trajectory for 3-dimensional rotational X-ray coronary angiography for a C-arm X-ray system that has at least two degrees of freedom, where the C-arm X-ray system is defined by a rotational movement of the C-arm expressed in a left/right coronary artery oblique angle, and a roll motion of the C-arm expressed in a caudal/cranial angle. The method includes generating of a 3-dimensional representation of a center-line of a body vessel in a region of interest. generating at least one optimal view map. Further, an optimal trajectory for the X-ray system within the optimal view map is determined, where an optimal trajectory is at least determined by movements of the C-arm within its two degrees of freedom allowing image projections with minimal foreshortening and/or overlap while minimizing an exposure to X-rays.

Optimal rotational trajectory determination for RA based on pre-determined optimal view map

A method is disclosed which allows for optimally viewing a portion of a patient vascular system to facilitate at least one of diagnosis and treatment the vascular system. The method includes acquiring a model of said vascular system based on image data generated by an imaging device, identifying a portion of interest of the vascular system including determining a central vessel axis for a vessel of interest, generating a foreshortening map of the portion of interest based on viewing angle of the imaging device position, with respect to the patient, generating an overlap map to determine an amount of overlap present for particular viewing angles based on imaging device position, and generating a feasibility map to model dimensions of the patient based on patient characteristics, imaging device configuration, foreshortening and overlap.

Optimal view map v.0.01

A control processor () causes the drives () of a mechanical arm scanner to move an x-ray source () and a detector along an elliptical trajectory (). The trajectory can be customized () to deviate from a true mathematical ellipse or to be only an arc segment. As the x-ray source and detector move along the trajectory, a large multiplicity of projection images are generated, at least when a contrast agent is present in the region-of-interest. A selectable limited subset of the generated projection images are selected for display in order to make an angiographic diagnosis.

Alternative acquisition scheme for coronary angiography

A method and apparatus of generating a hybrid three dimensional reconstruction of a vascular structure affected by periodic motion is disclosed. At least two x-ray images of the vascular structure are acquired. Indicia of the phases of periodic motion are obtained and correlated. Images from a similar phase of periodic motion are selected and a three dimensional modeled segment of a region of interest in the vascular structure is generated. A three dimensional volumetric reconstruction of a vascular structure is generated that is larger than the modeled segment. The modeled segment of interest and the volumetric reconstruction of the larger vascular structure are combined and displayed in human readable form.
