摘要： The method of some embodiments of the invention assists a user in guiding a medical instrument to a subsurface target site in a patient. This method generates at least one intraoperative ultrasonic images. The method indicates a target site on the ultrasonic image(s). The method determines 3-D coordinates of the target site in a reference coordinate system. The method (1) tracks the position of the instrument in the reference coordinate system, (2) projects onto a display device a view field as seen from the position with respect to the tool in the reference coordinate system, and (3) projects onto the displayed view field indicia of the target site corresponding to the position. In some embodiments, the field of view is a view not only from the position of the instrument but also from a known orientation of the instrument in the reference coordinate system. By observing the indicia, the user can guide the instrument toward the target site by moving the instrument so that the indicia are placed or held in a given state in the displayed field of view.

摘要： Intraoperative image(s) of a patient target site are generated by an intraoperative imaging system (e.g., ultrasound or X-ray). The intraoperative imaging system is tracked with respect to the patient target site and surgical instrument(s) (e.g., a pointer, endoscope or other intraoperative video or optical device). The intraoperative images, surgical instruments, and patient target site are registered into a common coordinate system. Spatial feature(s) of the patient target site are indicated on the images of the patient target site. Indicia relating the position and orientation of the surgical instrument(s) to the spatial feature(s) of the patient target site are projected on the images, with the indicia being used to correlate the position and orientation of the surgical instruments with respect to the target feature.

摘要： A surgical navigation system has a computer with a memory and display connected to a surgical instrument or pointer and position tracking system, so that the location and orientation of the pointer are tracked in real time and conveyed to the computer. The computer memory is loaded with data from an MRI, CT, or other volumetric scan of a patient, and this data is utilized to dynamically display 3-dimensional perspective images in real time of the patient's anatomy from the viewpoint of the pointer. The images are segmented and displayed in color to highlight selected anatomical features and to allow the viewer to see beyond obscuring surfaces and structures. The displayed image tracks the movement of the instrument during surgical procedures. The instrument may include an imaging device such as an endoscope or ultrasound transducer, and the system displays also the image for this device from the same viewpoint, and enables the two images to be fused so that a combined image is displayed. The system is adapted for easy and convenient operating room use during surgical procedures.

摘要： An image guided surgical procedure using an improved registration of pre-operative volumetric scan data is described. Volumetric scan data, acquired before surgery, is registered with respect to the patient and used to construct a volumetric perspective image of the surgical site. The improved registration of the volumetric scan data can be accomplished by generating a pattern of light on the patient's surface by moving a laser beam over the surgical site. The pattern of light is recorded by at least two cameras from different known fixed positions, digitized and used to form a laser reconstruction of the patient surface. This digital surface can then aligned with the volumetric scan data forming an improved volumetric perspective image of the surgical site.

摘要： The subject matter presented herein provides an efficacious system and method for diagnosing orthostatic intolerance and for treating orthostatic hypotension. A dynamic compression garment that comprises a servo-controlled splanchnic venous compression with automated binder system is used to regulate blood flow, for instance, during orthostasis. The system includes a programmable controller and a computing device in communication with the controller, an inflator, one or more sensors, and a power supply. The system can collect a user's biometric data, which may be transmitted to the user, a physician in charge of the user, or a third-party. Moreover, the biometric data may be incorporated into a machine learning model that can be used to further program the controller.
