Definitions
- the invention relates to an ultrasound applicator according to the features of the preamble of patent claim 1.
- the organs of interest for ultrasound scanning such as the kidneys, thyroid, liver, heart or, in women, the female breast, lie at quite different depths. This means that these organs do not always have the optimal position with regard to the focus of the scanning ultrasound lobe. In principle, this applies to all ultrasound applicators with direct coupling to the body surface only via a coupling gel.
- Such applicators are, for example, normal compound scanners, mechanical sector scanners and in particular also ultrasound arrays of any design, as described, for example, in the article "Real-Time Sonography with the Multison 400 Linear Array Scanner" by V. Zurinski and R. Haerten in the magazine “Electromedica” 46 (1978) Issue 4, described on pages 141 to 148.
- ultrasound applicators are also known in which the vibrating elements are coupled to the body via a water flow path.
- the device known from the brochure "VIDOSON 735 SM ultrasound real-time tomograph with water inlet section DATA E 441" from 1979 does not allow any variation in the distance of the vibrating elements from the body surface within the water inlet section without special measures, ultrasound Array of DE-PS 25 29 112 such a change in distance possible.
- Ultrasound applicator is specifically a sector scanner that scans line by line due to the curved design of the ultrasound array in a sector.
- a displacement device is provided which enables a change in the distance between the curved array and the coupling point on the body within the water flow path.
- the object of the invention is to design an ultrasound applicator according to the preamble of claim 1 in such a way that it can be easily and quickly adjusted to different depth sensing in the sense of the above explanations.
- the invention makes it possible for the ultrasound head to be preceded by a liquid bag (with, for example, water or an oil which conducts the ultrasound well or the like), which elastically changes the distance between sound-producing vibrating elements of the ultrasound head and body surface, which in turn changes the scanning depth.
- a liquid bag with, for example, water or an oil which conducts the ultrasound well or the like
- the liquid sack is in the simplest To assemble and it can be dismantled just as quickly if you want to switch from scanning areas close to the skin (e.g. thyroid, kidneys, female breast) to scanning deeper organs (e.g. liver, intestine or even heart). In the latter case, direct coupling then takes place again with the omission of the liquid bag.
- the dimensions of the liquid bag can be changed by inflating it to different extents, so that this enables a further depth variation when using such a bag.
- the ultrasound array is designated as 1 as an ultrasound applicator.
- the ultrasound array has a connection 2 for an electrical signal and power supply cable.
- the actual ultrasound head is labeled 2.
- a liquid bag 4 is connected upstream of the ultrasound head 2 with the transducer elements 3.
- the latter consists of a sheath 5 made of stretchable material, e.g. Natural rubber, which is filled with a liquid that conducts the ultrasound well, in particular water or a corresponding oil. In the present case, water is used as the filling material, which is also specially prepared against fungal attack by a special agent.
- the liquid bag 4 is clamped to the ultrasound head 2 of the array 1 by means of a simple clamping part 7, which has the shape shown in FIG.
- the clamping part from e.g. resilient plastic material, e.g.
- the water bag itself can have different dimensions corresponding to different application conditions. In the case of one and the same array, the dimensions of the liquid sack can be changed within certain limits by appropriately varying the amount of water inflated, so that this enables a further depth variation when using such a sack.
- a rail 12 is used to store the respective sack 4 in the clamping part 7, e.g. also made of plastic, which has the shape shown in Figure 3.
- the rail 12 is arranged in each case inside the liquid bag 4, as is the case, for example, is indicated in Figures 1 and 2.
- the fluid bag 4 connected upstream of the transducer elements 3 of the transducer serves as an elastic spacer; depending on its dimensions, it varies the depth at which the focus of the scanning lobe of the ultrasound head 2 comes to rest.
- organs in the area close to the skin can be scanned. If switching to lower organs is to be carried out on scanning, the sack 4 is removed again and the ultrasound head 2 with the transducer elements 3 is coupled directly (only via the coupling gel) to the body surface.
