Provided is to a system with an interface for providing visualization data for visualizing at least one section of a patient's eye, comprising an OCT device for capturing OCT scanning data by scanning the section of the patient's eye by means of an OCT scanning beam and comprising a computer unit for processing the OCT scanning data into the visualization data within the scope of an image rectification algorithm, which is designed to output the visualization data at the interface. The computer unit contains a view generation algorithm for calculating image data in relation to a view of a reference object arranged in the section of the patient's eye from geometry data about the reference object fed to the view generation algorithm and from the OCT scanning data obtained in relation to the reference object, wherein the computer unit has an algorithm control routine which specifies the image rectification algorithm and determines the image rectification algorithm from the image data of the view of the reference object calculated in the view generation algorithm and from OCT scanning data obtained in relation to the reference object by scanning the section of the patient's eye.

Rotating marker
20210386482 · 2021-12-16 ·

A marker for image guided surgery, consisting of a base, having a base axis, connecting to a clamp; and an alignment target. The alignment target includes a target region having an alignment pattern formed thereon, and a socket connected to the target region and configured to fit rotatably to the base, whereby the alignment target is rotatable about the base axis. The alignment target also includes an optical indicator for the socket indicating an angle of orientation of the alignment target about the base axis.

Passive tags, and systems and methods for using them

Markers, microwave probes, and related systems and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The marker includes an energy converter e.g., one or more photodiodes, for transforming energy pulses striking the marker into electrical energy, a switch, e.g., FET, coupled to the photodiodes such that light from a probe cause the switch to open and close. A pair of antenna wires are coupled to the switch to provide an antenna, the switch configured to open and close when light strikes the photodiodes to modulate signals from the probe reflected by the antenna back to the probe to identify the location of the marker. The marker also includes an electro static discharge (ESD) protection device coupled to the switch to provide protection against an electrostatic discharge event.

Embodiments of the invention provide a system and method for resecting a tissue mass. The system for resecting a tissue mass includes a surgical instrument and a first sensor for measuring a signal corresponding to the position and orientation of the tissue mass. The first sensor is dimensioned to fit insider or next to the tissue mass. The system also includes a second sensor attached to the surgical instrument configured to measure the position and orientation of the surgical instrument. The second sensor is configured to receive the signal from the first sensor. A controller is in communication with the first sensor and/or the second sensor, and the controller executes a stored program to calculate a distance between the first sensor and the second sensor. Accordingly, visual, auditory, haptic or other feedback is provided to the clinician to guide the surgical instrument to the surgical margin.

Enhanced 3D training environment

A method for immersively displaying a scanned environment of a region to a set of users in a training environment wearing augmented reality head display units. The training environment includes a pseudo-GPS system, which allows position tracking over time. This enables rehearsing military operations before they occur.

METHOD AND DEVICE FOR NON-INVASIVE MEASUREMENT OF AN INTRAOCULAR PRESSURE

A method of non-invasive measurement of an intraocular pressure (IOP), the method may include: obtaining an image of at least a portion of a specific element of a subject's eye; detecting at least a portion of the specific element in the obtained image; and determining a value of a geometric property of the specific element based on the obtained image, the determined value of the geometric property is indicative of an IOP value of the subject's eye. In some embodiments, the specific element comprises at least one of: at least a portion of a limbus and at least a portion of an anterior surface of a sclera of the subject's eye.

Vascular locating systems and methods of use

Disclosed are puncture sealing systems and methods of locating a puncture site within a vessel.

A marker (40) for image guided surgery, consisting of a base (94), having a base axis, connecting to a clamp (42), and an alignment target (44). The alignment target includes a target region (120) having an alignment pattern formed thereon, and a socket (124) connected to the target region and configured to fit rotatably to the base, whereby the alignment target is rotatable about the base axis. The alignment target also includes an optical indicator (162) for the socket indicating an angle of orientation of the alignment target about the base axis.

PATIENT MONITOR

Images obtained by a camera system (10) arranged to obtain images of a patient (20) undergoing radio-therapy are processed by a modeling unit (56,58) which generates a model of the surface of a patient (20) being monitored. Additionally the patient monitoring system processes image data not utilized to generate a model of the surface of a patient being monitored to determine further information concerning the treatment of the patient(20). Such additional data can comprise data identifying the relative location of the patient and a treatment apparatus (16). This can be facilitated by providing a number or retro-reflective markers (30-40) on a treatment apparatus (16) and a mechanical couch (18) used to position the patient (20) relative to the treatment apparatus (16) and monitoring the presence and location of the markers in the portions of the images obtained by the stereoscopic camera (10).
