The present invention relates to a monitoring apparatus for monitoring an ablation procedure. The monitoring apparatus comprises an ultrasound signal providing unit for providing an ultrasound signal that depends on received echo series of an object that is ablated. The monitoring apparatus further comprises an ablation depth determination unit for determining an ablation depth from the provided ultrasound signal. The ablation depth can be determined directly from the ultrasound signal and is an important parameter while performing an ablation procedure. For example, it can be used for determining the progress of ablation within the object and for determining when the ablation has reached a desired progression.

A spectroscopic system which determines a property of a biological structure in a volume of interest of a person includes a low cost objective lens for directing an excitation beam into a volume of interest and for collecting return radiation from the volume of interest. After detection of the return radiation and generation of spectroscopic signals, a correction unit performs a compensation for aberrations of the spectroscopic signals introduced by the low cost objective lens. Since the aberrations of the objective lens strongly depend on the lateral distance of the volume of interest from the optical axis of the objective lens, the correction unit uses a correction table providing an assignment between correction values and various lateral positions of the volume of interest.

Aberration correction for spectroscopic analysis

A property of a fluid is determined spectroscopically, such as for the purposes of in vivo blood analysis. First the position of a volume of interest through which the fluid flows is determined by an optical detection step by making use of an objective. Preferably the optical detection step is an imaging step. Next the objective is moved to bring the focal point of the objective into coincidence with the volume of interest. In this position an optical spectroscopic step is performed. This has the advantage that the measurement beam for performing the optical spectroscopy travels along the optical axis for optimum efficiency.
