Abstract
A method and system for guiding renal stone removal. The method includes steps for facilitating or guiding three stages of the intervention: renal access, stone removal, and a stone-free check. This is facilitated by a method which includes three stages: an intra-operative image guidance phase for obtaining CT-based imagery of the renal area; a renal access guidance phase in which the aforementioned CT-based imagery is used to generate intervention guidance imagery to guide renal access, and a stone-free check phase in which further intra-operative CT images are acquired to check the stone-free status of the patient.
Claims18
A processing unit comprising one or more processors configured to perform a computer-implemented method for interventional support during a renal interventional procedure for kidney stone removal, the method comprising:
- at least one intra-operative image acquisition phase, comprising:
- receiving computed tomography (CT) image data of an anatomical area which includes at least a portion of a kidney of a subject;
- an interventional image guidance phase, comprising:
- receiving real-time tool tracking data indicative of a positioning of an interventional tool for use in the interventional procedure,
- generating real-time guidance imagery based on the CT image data, and further based on the tracking data, the guidance imagery visualizing a position of the interventional tool relative to the anatomical area imaged in the CT image data,
- communicating with a user interface device to display the generated guidance imagery in real time on a display unit of the user-interface device;
- and
- a quality assurance check phase, following the interventional image guidance phase, comprising:
- communicating with a CT imaging apparatus to acquire further CT image data of said anatomical area using a CT imaging apparatus, for use in visualizing any residual stones or stone fragments, for use thereby in determining whether complete stone removal has been achieved, wherein the further CT image data is cone beam CT image data, and
- communicating with the user-interface device to display the further CT image data on the display unit of the user interface.
