Provided is a method for forming an implant with an autonomous manufacturing device. The method includes accessing a first computer-readable reconstruction of a being's anatomy; accessing a second computer-readable reconstruction of an implant; accessing a third computer-readable reconstruction comprising the first computer-readable reconstruction superimposed with the second computer readable reconstruction; generating at least one computer-readable trace from a point cloud; and forming an implant with an autonomous manufacturing device, wherein the autonomous manufacturing device forms the implant into a shape defined by at least one dimension of the computer-readable trace.

The invention relates to a marker body (10) for marking breast tissue for radiotherapy. The marker body (10) has an at least partly tube-like body (12) which is made from a soft elastic material and carries multiple radio-opaque marker elements (18). The at least partly tube-like body (12) is designed so that it offers hardly any resistance to an external, deforming force, but returns to its original shape in the absence of external forces. The at least partly tube-like body (12) has two free longitudinal ends (14, 16) which can be detachably interconnected or are interconnected, resulting in a tubular ring.

Systems, methods and a sensor alignment mechanism are disclosed for medical navigational guidance systems. In one example, a system to make sterile a non-sterile optical sensor for use in navigational guidance during surgery includes a sterile drape having an optically transparent window to drape the optical sensor in a sterile barrier and a sensor alignment mechanism. The alignment mechanism secures the sensor through the drape in alignment with the window without breaching the sterile barrier and facilitates adjustment of the orientation of the optical sensor. The optical sensor may be aligned to view a surgical site when the alignment mechanism, assembled with the sterile drape and optical sensor, is attached to a bone. The alignment mechanism may be a lockable ball joint and facilitate orientation of the sensor in at least two degrees of freedom. A quick connect mechanism may couple the alignment mechanism to the bone.

Systems and methods are provided for planning a procedure. A display device is configured to display a first virtual element. A controller device having a processor is configured to be in communication with the display device, and the controller device is further configured to direct the display device to display the first virtual element. A physical control element is in communication with the controller device, and is configured to correspond to the first virtual element such that an actual manipulation of the control element is displayed, via the processor of the controller device and on the display device, as a corresponding response of the first virtual element to the actual manipulation of the control element. Associated systems, methods, and computer program products are also provided.

A biopsy site marker includes a carrier, and a marker element. The marker element includes a primary coil, a first anchor and a second anchor. The primary coil is disposed within the carrier. At least a portion of the first anchor and the second anchor extend outwardly from opposite sides of the carrier. The first anchor and second anchor are configured to move relative to the primary coil to engage tissue at a biopsy site.

A method for calculating during use the geometric parameters of an x-ray imaging system, an object or a patient to be observed being placed between the x-ray source and a detector of x-rays having passed through the object or patient, wherein it includes at least the following steps: detecting at least one marker on the object or the patient or in proximity to the object, the marker being of unknown 3D position, acquiring a plurality of 2D images for a plurality of viewpoints of the imaging system, detecting the position of at least one marker in each of the acquired 2D images, estimating the projection matrices corresponding to the projections of the object at various viewing angles and reconstructing in 3D the position of a marker on the basis of the estimation of the projection matrices.

A surgical assembly for kinematically coupling two surgical components is provided. The surgical assembly includes a first surgical component having a receiver, which defines a cavity and has a plurality of constraint surfaces accessible in the cavity. The surgical assembly further includes second surgical component having a key, which has a triplicity of kinematic elements to repeatably position the key in the receiver. The surgical assembly further includes a preloading mechanism having a load member arranged to secure the key in the receiver such that the kinematic elements contact the receiver at the plurality of constraint surfaces such that the key is kinematically constrained to the receiver by being constrained by six points of contact with the receiver.

A method for visualizing and targeting anatomical structures inside a patient utilizing a handheld screen device may include grasping the handheld screen device and manipulating a position of the handheld screen device relative to the patient. The handheld screen device may include a camera and a display. The method may also include orienting the camera on the handheld screen device relative to an anatomical feature of the patient by manipulating the position of the handheld screen device relative to the patient, capturing first image data of light reflecting from a surface of the anatomical feature with the camera on the handheld screen device, and comparing the first image data with a pre-operative 3-D image of the patient to determine a location of an anatomical structure located inside the patient and positioned relative to the anatomical feature of the patient.

Mediated-reality imaging systems, methods, and devices are disclosed herein. In some embodiments, an imaging system includes a camera array configured to (i) capture intraoperative image data of a surgical scene in substantially real-time and (ii) track a tool through the scene. The imaging system is further configured to receive and/or store preoperative image data, such as medical scan data corresponding to a portion of a patient in the scene. The imaging device can register the preoperative image data to the intraoperative image data, and display the preoperative image data and a representation of the tool on a user interface, such as a head-mounted display.

Methods, devices, systems, and series of appliances are provided for dental implant positioning. One method for positioning an implant with dental treatment includes determining an implant location based on a virtual model of an optimized dental occlusion, moving one or more teeth using a first number of a series of dental appliances, from a first orientation to a second orientation, the second orientation exposing the implant location, placing an implant at the exposed implant location using a landmark included in at least one of the series of dental appliances, repositioning one or more teeth using a second number of the series of dental appliances, from the second orientation to a successive orientation.
