    摘要: The invention relates to a phantom for simulating the ultrasound guided insertion of a needle in a blood vessel of a human body site. The phantom comprises: a skin mimicking layer (2), formed in a first material; —a tissue mimicking layer (3), formed in a second material and at least one artificial blood vessel (4a, 4b, 4c), formed in a third material, the first, second and third material being arranged to reproduce both the mechanical and the ultrasound properties of the corresponding parts of the human body site. Thanks to the invention, the phantom permits a realistic simulation of a human body site behavior.

    摘要: A method and system for detecting blood vessels and precisely determining parameters in respect thereof, such as geometry, depth and diameter. Optical imaging, such as IR imaging, is used to obtain a general overview (16) of the blood vessel pattern in a region of interest from which a target vessel can be defined and its lateral position determined. Ultrasound imaging is then employed to precisely measure parameters, such as depth and diameter, in respect of the target vessel. The resultant system is of relatively low cost, and relatively simple to implement and use.

    摘要: The present invention provides a spectroscopic system and in particular a fiber optic probe for in vivo detection of vulnerable atherosclerotic plaque inside the cardiovascular system of a patient. Detection of vulnerable plaque is based on a location dependent measurement of concentration levels of cardiac marker molecules flowing in the blood stream. Concentration level determination is preferably based on surface-enhanced Raman spectroscopic techniques providing sufficient sensitivity for determination of these concentration levels. Acquisition of spectroscopic data during moving of the fiber optic probe through the cardiovascular system with controlled velocity allows to precisely locate vulnerable plaque in the cardiovascular system.
