Patent number: 11672505Abstract: A fusion imaging system co-registers and fuses real time ultrasound images with reference images such as those produced by MRI or CT imaging. In an illustrated implementation, previously acquired CT or MRI or ultrasound images are loaded into the system. An ultrasound system is operated in conjunction with a tracking system so that the ultrasound probe and images can be spatially tracked. A computerized image processor registers the probe position with a reference image of the anatomy being scanned by the probe and determines whether the probe appears to be inside the skin line of the subject. If that is the case it is due to probe compression of the subject, and the reference image is modified to locate the skin line in the reference image in front of the ultrasound probe. The modified reference images can then be readily co-registered and fused with the ultrasound images produced by the probe.Type: GrantFiled: April 21, 2022Date of Patent: June 13, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Cecile Dufour, Roberto Jose Ardon, Gary Cheng-How Ng, Thomas Shu Yin Tang
