    摘要: A method of performing surface-enhanced resonant Raman spectroscopy (SERRS) in respect of a sample (100) provided on an aggregated colloid nano-particle having a plasmon absorption band similar to that of a target molecule. The sample is irradiated at a first wavelength (λ1).coinciding with the absorption band of the plasma, to obtain (12) a SERRS spectra for deriving (10) a fingerprint of the target melecule, and at a second wavelength (λ2), coinciding with the absorption band caused by aggregate of said nano- particles, to obtain (14) a SERS spectra for monitoring (16) said aggregation.

    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.
