  • Patent number: 10265854
    Abstract: Methods and devices for identifying and defining a safety zone for restricting movement of a robotic arm in an operating room during a medical procedure are disclosed. The disclosed method utilizes medical navigation system, which receives an initiation input indicating initiation of defining of the safety zone. In response to receiving the initiation input, the system tracks an instrument and determines the location of the tracked instrument relative to a reference point. The system detects changes in the location of the tracked instrument until a termination input is received at the medical navigation system. The termination input indicates the termination of the defining of the safety zone. The system stores, in memory, change data indicative of the changes in the location of the tracked instrument. The data identifies the safety zone relative to the reference point.

  • Patent number: 9125669
    Abstract: A haptic robotic system for reaming an acetabulum prior to inserting an acetabular cup is more accurate than conventional instruments and may reduce the risk of dislocation and improve durability of a hip implant. Disclosed is a three-dimensional tool path, referred to as a haptic volume. Once the haptic volume is implemented into the software of a haptically constrained surgical robotic system, the cutting tool or reamer can only be utilized within the haptic volume. The haptic volume guides the surgeon in preparing the final reamed bone surface with a greatly reduced chance of the reaming unintended bone and greatly increases the chance that the reaming procedure may be carried out using one reaming tool, or using a single-stage reaming process.

    Abstract: The system and method of the present application includes an image guided radiation therapy (IGRT) system, combined with a medical ventilator, to form a closed-loop system to optimize treatment of a tumor for patients who cannot comply with a normal respiratory management procedure. The ventilator may be used to generate respiratory maneuvers to facilitate clean images for dose planning, so that clinicians can more clearly visualize a target with fewer of the image artifacts associated with respiratory motion. The combined IGRT and ventilation systems approach facilitates treatment of specific organs most susceptible to respiratory motion artifact, and helps minimize the doses to the heart in left-breast treatments. Improved positioning of the anatomical target structures for exposure to external beam radiation may be accomplished through combinations of respiratory-gating, respiratory pause, and selective right or left lung mechanical ventilator techniques.

    Abstract: The invention generally relates to intravascular imaging and methods of improved image quality by triggering image operations with a vessel flush. The invention provides systems and methods for intravascular imaging in which a flush such as the influx of clear saline or radiopaque dye triggers the imaging operation. The flush is detected by a mechanism—such as a pressure sensor or optical device on the imaging catheter, an external angiography system, or other device—that uses detection as a trigger to initiate imaging. Thus, when the blood is flushed, the catheter automatically takes a picture of the vessel wall.

  • Patent number: 8706194
    Abstract: This patent document discusses assemblies and methods for remotely detecting a position of a surgical instrument in the presence of a magnetic field. In varying examples, a position detection system includes an encoder coupled to move in concert with the instrument. The encoder includes an a translucent substrate and light blocking indicia disposed thereon. A light source and a light detector array are effectively disposed outside of the magnetic field. Light from the light source is carried to an encoder first side using an input optical fiber, while the light passing through the encoder is received at an encoder second side by an output optical fiber. The light received by the output optical fiber is transmitted to the light detector array, which converts the received light to position representative electrical signals. Such signals are subsequently transmitted to a control module adapted to formulate and convey a position of the instrument.

    Abstract: A method for collecting three-dimensional data of an object from a series of projection images recorded by a biplane C-arm system is provided. A cardiac activity is recorded. The cardiac frequency and a start cardiac phase are determined for calculating parameters of the C-arm planes. The C-arm planes are set with the parameters and data is acquired in the start cardiac phase. The C-arm planes are uniformly rotated at a same speed in a forward motion over an angular area and record data at different angular areas at different cardiac phases. Data is acquired in the start cardiac phase after termination of the forward motion. The C-arm planes are uniformly rotated at a same speed in a backward motion over an angular area and records data at different angular areas at different cardiac phases. The captured data are reconstructed after termination of the backward motion upon completed acquisition.

  • Patent number: 8526694
    Abstract: An image data subtraction system enhances visualization of vessels subject to movement using an imaging system. The imaging system acquires data representing first and second anatomical image sets comprising multiple temporally sequential individual mask (without contrast agent) and fill images (with contrast agent) of vessels respectively, during multiple heart cycles. An image data processor automatically identifies temporally corresponding pairs of images comprising a mask image and a contrast enhanced image and for the corresponding pairs, automatically determines a shift of a contrast enhanced image relative to a mask image to compensate for motion induced image mis-alignment. The image data processor automatically shifts a contrast enhanced image relative to a mask image in response to the determined shift.
