摘要： An invasive medical device includes a fluid path of microbubbles which is imaged by ultrasound during use of the device. The fluid path extends through the device, preferably to the distal end of the device, so that the diffuse reflection of ultrasound from the microbubbles can be received to image the location of the device. The fluid path can be open, terminating at the tip of the device, or can be a closed path of a circulating microbubble fluid used for imaging and/or cooling.

摘要： The invention relates to a property determining apparatus for determining a property of an object, which is preferentially a heart. An ultrasound signal providing unit provides an ultrasound signal of the object and a scatter determination unit (8) determines at least one scatter value being indicative of a scatter of the ultrasound pulse by a fluid perfusing the object depending on the ultrasound signal. A property determination unit (15) determines a property of the object depending on the at least one scatter value. In contrast to tissue damage detection methods based on bubble formation, an object property related to perfusion, like whether tissue is ablated or non-ablated, can relatively directly be determined based on the scatter of the ultrasound pulse by the fluid, thereby increasing the accuracy of determining a property of the object.

摘要： The present invention relates to a signal measurement system (100, 200, 300) for measuring a signal, the system comprising a signal detection unit (41) for detecting a raw signal, a signal processing unit (42) and a signal cable (10) electrically connecting the signal detection unit (41) with the signal processing unit (42). The signal cable (10) comprises a signal conductor (1, 2) for electrically conducting a first signal from the signal detection unit (41) to the signal processing unit (42), which first signal comprises at least the raw signal, a reference conductor (11, 12) for detecting and electrically conducting to the signal processing unit (42) only a noise signal induced by a movement of the signal cable (10) or by electromagnetic interference. In this way the effect of noise on the signal quality is reduced caused by movement of the signal cable (10) or other sources of noise that induce a noise signal in the signal cable (10), such as electromagnetic interference, while at the same time not increasing the power usage or power loss.

摘要： The invention relates to a method of and device for monitoring a vital parameter of a patient by emitting light onto tissue of the patient with at least one light source (1, 2) and collecting light which is transmitted through the tissue and/or which is reflected from the tissue. The emitted light is multiplexed according to a predefined multiplexing scheme having a plurality of multiplexing channels, and the collected light is detected according to the predefined multiplexing scheme, resulting in a plurality of detection channels (16, 17, 18, 19). At least one of the multiplexing channels is arranged to be a dark multiplexing channel for which no light is emitted by the at least one light source (1, 2), resulting in a dark detection channel (19), and the signal of this dark detection channel (19) is used for generating a reference signal for reducing interference in the signal of at least one of the other detection channels (16, 17, 18). In this way a versatile and reliable possibility of monitoring a vital parameter of a patient with a high signal-to-interference ratio is provided.

摘要： The invention relates to a method and apparatus for processing a cyclic physiological signal (30, 40, 52, 53, 54). The method comprises the steps of repeatedly collecting (2) the physiological signal (30, 40, 52, 53, 54) over a time period (31, 32, 33) covering two or more cycles of the cyclic physiological signal (30, 40, 52, 53, 54), wherein a next time period (31, 32, 33) is adjacent to or overlaps with a previous time period (31, 32, 33), extracting values (3, 13) of a set of predefined parameters from the physiological signal (30, 40, 52, 53, 54) within each time period (31, 32, 33) which parameter values characterize the physiological signal (30, 40, 52, 53, 54) within the time period (31, 32, 33), and classifying (4, 14) the physiological signal (30, 40, 52, 53, 54) within each time period (31, 32, 33) based upon the extracted set of predefined parameter values. This provides for an efficient analysis of a cyclic physiological signal which is especially suitable for continuous monitoring of patients where a trend of a reliable physiological signal is more important than an instantaneous measurement of a reliable physiological signal, such as in a general ward environment of a hospital and/or in a home environment.
