Embodiment Construction

[0080] refer to figure 1, which shows a schematic block diagram of a system SYS for marker-assisted navigation as may be used for medical interventions such as minimally invasive surgical (MIS) interventions, in situ examinations and similar procedures. In particular, the system SYS preferably supports imaging during such interventions.

[0081] Medical applications, especially MIS applications, including pulmonary interventions, such as VATS. VATS interventions include removal of the lesion from lung tissue, such as wedge resection and similar procedures. Other MIS medical applications may include examination of the bowel, urinary tract, esophagus, liver and other organs or groups thereof.

[0082] Although medical applications are primarily envisaged herein, non-medical applications are also envisaged, such as navigation in plumbing systems, cave systems, or other difficult-to-access environments where a certain object needs to be located.

[0083] The system SYS broadly ...

Abstract

A method and related system for marker-based navigation. A first image is captured (S530) with a medical imaging apparatus (ENDO), whilst a light source (LS1) of an implanted marker device (MD) is in a low intensity state and a second light source (LS2) of the medical imaging apparatus (IA) is in a high intensity state, higher than the low intensity state of the marker. A second image is captured (S560) with the medical imaging apparatus (ENDO), whilst the light source (LS1) of the implanted marker device is in a high intensity state and the second light source (LS2) of the medical imaging apparatus (IA) is in a low intensity state, lower than the high intensity state of the marker. The two images may then be combined to obtain a combined image that represents the location of the marker at high signal -to-noise-ratio.

Description

technical field [0001] The invention relates to a system for marker-based navigation, an implantable marker device for navigation support, a medical imaging device, a method for marker-based navigation, a computer program element and a computer readable medium. Background technique [0002] One of the major challenges during oncological surgery is the localization of lesions. This may be a problem particularly with regard to small lesions and minimally invasive surgical procedures. [0003] A good example is the use of video-assisted thoracoscopic surgery (VATS) to resect lung lesions, especially wedge resection. A wedge resection is the removal of tissue where the incision does not have to follow the boundaries of the anatomy. [0004] The lungs will contract during VATS, which will distort the spatial relationship between points within and on the lungs. Deflating often makes localizing the lesion based on preoperative imaging impossible. VATS also means only indirect a...
