  • Publication number: 20200069264
    Abstract: In an embodiment, a medical system is disclosed. One embodiment of the medical system comprises a medical processing unit in communication with an intravascular instrument configured to be moved longitudinally within a body lumen and in further communication with a radiographic imaging source configured to obtain radiographic images of the intravascular instrument while the intravascular instrument is moved longitudinally within the body lumen. The medical processing unit is configured to receive radiographic images obtained by the radiographic imaging source, track the intravascular instrument within the radiographic images while the intravascular instrument is moved longitudinally within the body lumen, calculate a movement speed based on the tracking, compare the calculated movement speed to a predefined target movement speed, generate a speed-adjustment suggestion based on the comparison, and output the speed-adjustment suggestion to a display for review by a user.

  • Publication number: 20190282199
    Abstract: The present disclosure relates generally to the imaging of blood vessels, and in particular, to the detection of one or more borders of a blood vessel. In some embodiments, a medical imaging system is configured to detect a primary border of a blood vessel and one or more alternative borders of the blood vessel. For example, in some embodiments, a medical imaging system includes an imaging device configured to obtain an image of a blood vessel, a processing unit, and a user display. The processing unit can be configured to receive the image of the blood vessel and perform an analysis of the image to identify a primary candidate border and an alternative candidate border of the blood vessel. The primary candidate border and alternative candidate border can represent candidates for a single boundary of the blood vessel.

  • Patent number: 10368836
    Abstract: Systems and methods for multi-modality data processing are provided. Some embodiments are particularly directed to interpreting gesture-based commands in a multi-modality processing system. In one embodiment, a method for interpreting user input in a medical processing system includes receiving a state designator corresponding to a mode of operation of the medical processing system, where the mode of operation includes a value representative of a modality selected from the group consisting of: IVUS, OCT, pressure, and flow. A list of active commands is generated based on the received state designator. A user input sequence is received from one or more user input devices. The medical processing system correlates the user input sequence to a command of the list of active commands, and the command is utilized to control operation of a component of the system. The list of active command may include a subset of commands common to multiple modalities.
