An ultrasound system employs an ultrasound probe (), a strain sensor () and a workstation (). The ultrasound probe () includes an ultrasound transducer for acquiring ultrasound images () of an anatomical region. The strain sensor () is arranged on the ultrasound probe () to measure a longitudinal strain applied by the anatomical region to the ultrasound probe () as the ultrasound transducer acquires ultrasound images () of the anatomical region. The strain sensor () encircles a longitudinal axis of the ultrasound probe () and is spaced from the ultrasound transducers relative to the longitudinal axis of the ultrasound probe (). The workstation () reconstructs an ultrasound volume () from the ultrasound images () acquired by ultrasound transducer, and responsive to the longitudinal strain measured by strain sensor (), determines an axial force and/ora bending force applied by the anatomical region to the ultrasound probe () as the ultrasound transducer acquires ultrasound images () of the anatomical region.

An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.

An electromagnetic ('EM') tracking configuration system employs an EM quality assurance ('EMQA') () and EM data coordination (&#x201c;DC&#x201d;) system (). For the EMQA system (), an EM sensor block () includes EM sensor(s) () positioned and oriented to represent a simulated electromagnetic tracking of interventional tool(s) inserted through electromagnetic sensor block () into an anatomical region. As an EM field generator () generates an EM field () encircling EM sensor(s) (), an EMQA workstation () tests an EM tracking accuracy of an insertion of the interventional tool(s) through the EM sensor block () into the anatomical region. For the EMDC system (), as EM field generator () generates EM field () encircling a mechanical interaction of EM calibration tool(s) () with a grid () for guiding interventional tool(s) through gird () into an anatomical region, the electromagnetic data coordination workstation () establishes a coordination system for electromagnetically tracking an insertion of the interventional tool(s) through grid () into the anatomical region.

The electromagnetic actuator () includes a magnetorheological elastomer ('MRE'), wherein the MRE is operable to be transitioned between a plurality of shapes dependent upon a variable strength of a magnetic field applied to the MRE, and wherein each shape of the MRE actuates the mechanical gripper () to one of the gripping poses. The force feedback controller () is operable to control the variable strength of the magnetic field applied to the MRE based on an estimation of a gripping force of the mechanical gripper () and on a sensing of a load force of the object responsive to the gripping force of the mechanical gripper ().

An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of the insertion of multiple needles into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.

A calibration/surgical tool includes an electromagnetic sensor array of two or more electromagnetic sensors in a known geometrical configuration. Electromagnetic tracking errors are characterized by a mapping of pre-operative absolute and relative errors based on a movement of a calibrated calibration/surgical tool through a pre-operative electromagnetic field. Using statistical mapping, a desired absolute error field is measured either in the clinic as the part of daily quality control checks, or before the patient comes in or in vivo. A resulting error field may be displayed to the physician to provide clear visual feedback about measurement confidence or reliability of localization estimates of the absolute errors in electromagnetic tracking.

The present invention relates to a method of generating an image having a desired brightness, which image is generated by means of a device provided with at least one light source, at least one electro-optical light modulation panel and at least one light-control device. The light from the light source is converted into an image having a desired brightness via at least the electro-optical light modulation panel and the light-control device. The image to be projected is analyzed in a regulator, whereafter the electro-optical light modulation panel and the light-control device are driven, while a too bright image is generated by means of the electro-optical light modulation panel, which image is converted by means of the light-control device into an image having a desired brightness and a desired contrast.

An electro-magnetic tracking system includes a system controller having a sensor interface, a generator, and a positioning and angular orientation configuration. The generator is responsive to the system controller for generating an electro-magnetic field that includes a tracking volume of highest accuracy. The highest accuracy corresponds to an accuracy of the sensor interface and system controller to detect a sensor physically located within the tracking volume versus a lesser accuracy of the sensor interface and system controller to detect the sensor if the sensor is located outside of the tracking volume. The positioning and angular orientation configuration is coupled to the field generator for visibly optimizing (i) a positioning and/or (ii) an angular orientation of the electro-magnetic field generator such that the tracking volume lies within a centroid of a physical volume of interest, thereby enabling a detection of a sensor within the tracking volume with a highest accuracy.

A head-mounted projection display system is characterized by a pair of head-mounted low-power image projectors mounted adjacent the eyes of the viewer, and aimed to project in a direction along the line of sight of the viewer toward a high-gain, retro-reflective screen. Stereoscopic viewing is enabled by projecting separate images to the right and left projectors. The retro-reflectivity of the screen ensures that the right and left images will be returned to the right and left eye, respectively.
