摘要： The invention relates to a medical apparatus (120,130) having a sensor (100,110) for detecting a force acting on the medical apparatus (120,130) in a longitudinal direction. The medical apparatus (120,130) comprises an opto-mechanical force transducer having a flexible part (22,42) for receiving the force, an optical guide (1) having an outcoupling surface (11) that faces the flexible part (22,42) of the opto-mechanical force transducer, and a photodetector which detects an interference pattern composed of light (32) in the optical guide (1) that is reflected from the outcoupling surface (11) of the optical guide (1) and of light (33) in the optical guide (1) that is reflected from the flexible part (11) of the opto-mechanical force transducer. The use of the interference pattern composed of the light reflected from the out-coupling surface of the optical guide and the light reflected from the flexible part of the opto-mechanical force transducer results in a more accurate measurement of the force acting on the medical apparatus.

摘要： A monitoring apparatus for monitoring an ablation procedure applied to an object comprises an ultrasound signal providing unit for providing an ultrasound signal. The ultrasound signal is produced by sending ultrasound pulses out to the object, by subsequently receiving dynamic echo series after the ultrasound pulses have been reflected by the object, and finally by generating the ultrasound signal depending on the received dynamic echo series, whereby ultrasound scattering properties of the object are determined that represent blood perfusion. The monitoring apparatus further comprises an ablation depth determination unit for determining an ablation depth from the provided ultrasound signal.

摘要： The invention relates to an imaging apparatus (1) for imaging an interior of an object (2). The imaging apparatus (1) comprises a first ultrasound sensor and a second ultrasound sensor for sensing the interior of the object at different frequencies, wherein the ultrasound sensing signals from the first ultrasound sensor are used for generating a first ultrasound image and a the ultrasound sensing signals from the second ultrasound sensor are used for generating a second ultrasound image. A larger frequency generally provides a smaller depth of penetrating the interior of the object and a larger spatial resolution than a smaller frequency. The imaging apparatus (1) can therefore provide the capability of simultaneously imaging the interior of the object with different spatial resolutions and at different penetration depths. This allows the imaging apparatus to improve the quality of imaging the interior of the object.

摘要： 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.

摘要： A medical ultrasound device is disclosed. The device comprises an elongated body having a proximal end and a distal end region (1). One or more ultrasound transducers (4) for generating acoustic radiation are positioned in the distal end region, inside the elongated body. A transmission element (5) which is substantially transparent to acoustic radiation is positioned in the radiation path of the acoustic radiation, and a controller unit is operatively connected to the ultrasound transducer. The transmission element and the one or more ultrasound transducers are mounted so that an acoustic path length (8) between the transmission element (5) and the ultrasound transducer (4) varies with contact force (10) imposed to the distal end region. The controller unit detects the acoustic path length between the ultrasound transducer and the transmission element and determines the contact force from the detected acoustic path length. In an embodiment, the medical device is an ultrasound RF ablation catheter.
