Problems solved by technology

Assessment of tissue ablation using light-scattering spectroscopy is less accurate because of the small penetration depth of light into tissue and because of significant changes in tissue architecture and tissue perfusion, which adversely affect the interpretation of light-scattering spectroscopy

Embodiment Construction

[0095] figure 1A property determination device 1 for determining properties of objects is shown schematically and exemplarily. The property determining device 1 comprises an image providing unit 2 for providing an image of an object 3 , which in this embodiment is the heart of a person 20 . The property determining device 1 further comprises a catheter 21 comprising an optical sensor for generating optical sensing data indicative of an optical property of the object and an ultrasonic sensor for generating ultrasonic sensing data indicative of an ultrasonic property of the object. measurement data. Said catheter allows introducing said optical sensor and ultrasound sensor into the body of a person 20 in order to determine the properties of the inner wall of the heart 3 . The property determining device 1 also includes an energy application element, which in this embodiment is an RF electrode, for applying energy to the inner wall of the heart 3 . The energy application eleme...

Abstract

The invention relates to a property determination apparatus (1) for determining a property of an object (3). Optical sensing data being indicative of an optical property of the object and ultrasound sensing data being indicative of an ultrasound property of the object are generated, and a property determination unit (75) determines a property of the object based on at least one of the optical sensing data and the ultrasound sensing data. Since light and ultrasound have generally different penetration depths and scattering properties with respect to the object, a property of the object can be determined with good quality, even if the quality of one of the optical sensing data and the ultrasound sensing data is reduced by, for example, a relatively small penetration depth, or if one of the optical sensing data and the ultrasound sensing data is less suitable for determining a desired property of the object.

Description

technical field [0001] The present invention relates to a property determining device, a property determining method and a property determining computer program for determining the properties of an object. Background technique [0002] US 2006 / 0229515 A1 discloses an optical method and device for assessing the presence of tissue changes, in particular tissue ablation, using optical fiber enabled light scattering spectroscopy. Assessment of tissue ablation using light-scattering spectroscopy is less accurate because of the small penetration depth of light into tissue and because of significant changes in tissue architecture and tissue perfusion, which adversely affect the interpretation of light-scattering spectroscopy. Contents of the invention [0003] It is an object of the present invention to provide a property determination device, a property determination method and a property determination computer program for determining properties of an object, wherein the determi...
