Abstract
The present invention relates to supporting an interventional procedure involving a device, such as a cardiovascular procedure. First and second image data acquired using different imaging apparatus, for example X-ray and ultrasound image data, are co-registered. A device is firstly identified in 2D X-ray images; corresponding identification information is then used to generate a view from 3D ultrasound image data that includes a cross-section of the device to be identified subsequently. Following the identification, a 3D position and orientation of the device are available. Such information may advantageously be used in setting up optimal ultrasound views for image-based guidance of the ongoing procedure.
Claims15
An apparatus for tracking a device during a medical procedure involving the device, comprising:
- an input unit configured to receive first image data and second image data, wherein the first and second image data include at least a portion of said device and wherein the first and second image data had been acquired using different imaging apparatus, and
- a processing unit configured to:
- establish a co-registration between the first and second image data;
- identify a device in the first image data;
- generate an image from the second image data using first identification information of the device as identified in the first image data, and
- further identify the device in the generated image.
A method for tracking a device in medical image data, comprising the steps of:
- a) acquiring (S1) first and second image data using different imaging apparatus,
- wherein the first and second image data include at least a portion of said device;
- b) establishing (S2) a co registration between the first and second image data;
- c) identifying (S3) a device in the first image data;
- d) determining (S4) identification information of the device;
- e) generating (S5) an image from the second imaging data based on the identification information, and
- f) further identifying (S6) the device in the generated image.
