Abstract: 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.

Abstract: A photoacoustic medical-imaging device includes a wavelength conversion assembly (108) configured for outputting laser pulses at a targeted wavelength. It also includes a photoacoustic probe configured for acoustic coupling to a patient, for directing the pulses, and for acquiring, in response, radiofrequency data for photoacoustic imaging. It may include an optical fiber bundle (120) that comprises an optical fiber having an input end, and be configured for illuminating, with a homogenous beam, so as to conform to an acceptance angle (160) of the fiber at that end. It may also include a light collimator, and a diffuser for receiving the outputted laser pulses from the collimator. The diffuser may be configured for spreading a focus of the pulsed light (148) over an input aperture of the bundle to equalize the light received by different constituent optical fibers of the bundle. The assembly may include a dye cell (132), and may reside in the probe.

Abstract: The present invention relates to a monitoring apparatus (101) for monitoring an ablation procedure. The monitoring apparatus (101) comprises an ultrasound signal providing unit for providing an ultrasound signal that depends on received echo series of an object (4) that is ablated. The monitoring apparatus (101) further comprises an ablation depth determination unit (103) 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 (4) and for determining when the ablation has reached a desired progression.
