Description

WAVE SHAPING AND SCATTERING UNIT FOR AN ULTRASONIC

TRANSDUCER

TECHNICAL FIELD

[0001] The present disclosure relates generally to generation and focusing of energy waves in general, e.g., sonic waves and ultrasound waves, and particularly to a wave shaping and scattering unit of an ultrasonic transducer, useful in medical treatments, such as but not limited to, stimulation of cell metabolism, and other non-medical uses, such as but not limited to, non-destructive testing of structures, capable of generating multi-directional energy waves having multiple resonant frequencies.

BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Researches indicate that cells/organs/living organisms respond to internal as well as external surroundings. It has been observed that a slight change in pH levels within a cell can actuate a certain protein synthesis and can halt another for the same function. For example, a carcinogen is needed to trigger a change in behaviour of a healthy cell and make the cell start expressing proteins which turn the cells cancerous. If an unhealthy change in environment can alter the state of a cell, then the converse should be true too. A healthy environment should trigger a healthy change.

[0004] Autonomic nervous system (ANS) in human beings is a control system that acts largely unconsciously and regulates bodily functions such as heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal to name a few. Humans do not have much control over their heart rate or breathing. However, a soothing melody lowers our heart rate, hearing a loud explosion leads to higher heart palpitations. Such bodily functions are governed by the ANS through cells and organs present throughout body of a human being.

[0005] It has been profoundly envisaged that sound and vibrations bypass the conscious mind and have a direct effect on the ANS, thus, releasing regulatory hormones and enzymes and changing internal as well as external environment of various cells and organs. It is also a well researched fact that every healthy living organism/cell resonates within a defined frequency range. Also, for unhealthy/sick cells the defined frequency range changes that leads to losing of desired vibrancy and vitality of the unheal thy/sick cells. Further, imposing external electromagnetic stimulation like radio waves disturbs vibrancy and vitality of healthy cells, impacts its resonance and eventually causing cell lysis, a medical condition that refers to the breaking down of membrane of a cell, often by viral, enzymic, or osmotic mechanisms that compromise integrity of the cell.

[0006] Ultrasonic which is routinely used for diagnostic applications throughout the world is now being adopted in various fields of drug delivery systems and other therapeutic use. Interactions of acoustic ultrasonic with biological tissues play an important role in biomedical applications of ultrasonic. Low intensity ultrasonic is known to permeate the skin, modulate the cell membrane and alter its properties possibly activating signal transduction pathways. The energy absorbed by the enzymes from the ultrasonic effects the overall function of the cell.

[0007] Currently available ultrasonic transducers to stimulate cell metabolism typically incorporate means to shape and scatter an input wavefront into desired shape and form by passing the input waveform through a set of filters in order to generate an output waveform having desired shape and form. However, such ultrasonic transducers are primarily based around a single resonant frequency and do not provide for generation of resonant frequencies spanning over various energy wave ranges.

[0008] There is therefore a need in the art to provide a wave modulating unit for an ultrasonic transducer capable of shaping and scattering energy waves including any or a combination of ultrasound waves and sonic waves to obtain multi-beam and multi-directional energy waves capable of generating ultrasonic vibrations.

[0009] As used in the description herein and throughout the claims that follow, the meaning of“a,”“an,” and“the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of“in” includes“in” and“on” unless the context clearly dictates otherwise.

[0010] In some embodiments, the numerical parameters set forth in the written description and attached claims are approximations that can vary depending upon the desired properties sought to be obtained by a particular embodiment. In some embodiments, the numerical parameters should be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of some embodiments of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as practicable. The numerical values presented in some embodiments of the invention may contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.

[0011] The recitation of ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate value falling within the range. Unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g.“such as”) provided with respect to certain embodiments herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the invention.

[0012] Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all groups used in the appended claims.

[0042] In an embodiment, the wave shaping and scattering unit further includes a parabolic reflector to shape the incoming wavefront. In an embodiment, the parabolic reflector further assists in shaping and/or modulation of transmission beam angle of the incoming wavefront beams. The transmission beam angle of the incoming wavefront beams is modulated by adjusting focal length of the parabolic reflector.

[0043] In an embodiment, the incoming wavefront is generated by a piezo crystal fitted at a focal area of the parabolic reflector.

[0044] In an embodiment, the wave sheer grill is coupled with at least one resonator plate to generate standing waves. In an embodiment, the at least one resonator plate assists in attenuation of the incoming wavefront and lateral traverse length of the standing waves prior to emission of the energy waves from the wave sheer grill.

[0049] In an aspect, the present disclosure provides a grill sheer having a plurality of slots with a blocking element adapted to block at least a portion of the grill sheer, thereby blocking a number of slots of the plurality of slots. The grill sheer can be in the form of a circular disc, a square plate, a polygon shaped plate and the likes. The grill sheer can enable scattering of waves passing through the plurality of slots by restricting motion of a portion of the waves by the blocking element.

[0050] FIG. 1 illustrates an exemplary perspective view of proposed wave sheer grill of wave shaping and scattering unit of an ultrasonic transducer in accordance with an embodiment of the present disclosure. In an aspect, the wave shaping and scattering unit can include a wave sheer grill 100 and a parabolic reflector 300 (as shown in FIG. 3) to effectively shape and scatter energy wavefront generated thereof in a forward direction.

[0051] In an embodiment, the wave sheer grill 100 can include a plurality of slots 102 to segregate/separate an incoming wavefront into a plurality of beams as to obtain multi-beam energy wavefront as output of the wave sheer grill 100. In an embodiment, the plurality of slots 102 further direct the plurality of beams of the incoming wavefront into multiple directions to obtain multi-directional energy wavefront as output of the wave sheer grill 100. [0052] In an embodiment, the wave sheer grill 100 can be coupled with at least one resonator plate 104 (as shown in FIG. 2B) to generate standing waves having constant peaks with amplitude of such standing waves at a point in space varying with time, but their phase staying constant with respect to time. In an embodiment, the at least one resonator plate 104 can assist in attenuation of the incoming wavefront and lateral traverse length of the standing waves prior to emission of the energy waves from the wave sheer grill 100. In an embodiment, attenuation of the incoming wavefront and lateral traverse length of the standing waves are dependent on diameter and shape of the at least one resonator plate 104 and can be modulated by changing any or a combination of the diameter and shape of the at least one resonator plate 104.

[0053] In an embodiment, the wave shaping and scattering unit can be configured to modulate parabolic spin angle of the energy wavefront. In an embodiment, the wave shaping and scattering unit can further be configured to block at least a portion of the incoming wavefront and the standing waves. In an embodiment, the wave shaping and scattering unit can further be configured to modulate of the donut shaped/toroidal incoming wavefront. In an embodiment, the wave shaping and scattering unit can further be configured to slice of the donut shaped/toroidal incoming wavefront at appropriate grill angles.

[0054] In an embodiment, the wave shaping and scattering unit can further include a parabolic reflector 300 to shape the incoming wavefront. In an embodiment, the parabolic reflector can assist in shaping and/or modulation of transmission beam angle of the incoming wavefront beams. The transmission beam angle of the incoming wavefront beams can be modulated by adjusting focal length of the parabolic reflector.

[0055] In an embodiment, the incoming wavefront is in the form of donut shaped/toroidal waves generated by a piezo crystal that is coupled/fitted to a focal area of the parabolic reflector.

[0056] In an embodiment, the standing waves are generated as a result of interaction of the emitted waves and reflected waves between a parabolic reflector (not shown) of the wave shaping and scattering unit and the resonator plate 104. The piezo crystal is the primary source emitting the incoming/primary wavefront that are tuned to generate primary standing waves. The primary standing waves as they traverse through the wave shaping and scattering unit create secondary standing waves. This interaction and cross talk produces a toroidal/donut shaped wavefront which is sliced at appropriate angles at the wave sheer grill 100, thereby generating a multi-directional energy wavefront capable of engulfing a subject being treated by the wave generating device from all directions.

[0057] Referring now to FIGs. 2A and 2B, where front side and rear side of the wave sheer grill 100 are shown respectively, thickness of the wave sheer grill 100 can range between 0.5 mm to 6.5 mm with the plurality of slots extending up to a thickness of 3 mm of the wave sheer grill. In addition, the wave sheer grill 100 can be in the form of a disc with diameter of the wave sheer grill ranging between 30 mm and 72 mm.

[0058] In an embodiment, front side of the wave sheer grill 100 can have the plurality of slots 102 and rear side of the wave sheer grill 100 can be fitted with the resonator plate 104 so as block at least a portion of the incoming wavefront and generate the standing waves due to the presence of the resonant plate 104. The wave sheer grill 100 can allow passing of the incoming wavefront from the slots 102 that are not blocked by the resonator plate 104 to emit the desired multi-beam and multi-directional energy wavefront having sonic waves encapsulated by ultrasound waves.

[0059] In an embodiment, the wave sheer grill 100 can emit the multi -beam and multi- direction energy wavefront that includes multi-directional low frequency ultrasound carrier sweep with an encapsulated multi-directional sonic frequency sweep having frequency ranges that covers natural resonant frequency range of human body as a whole as well as at cellular level.

[0060] FIG. 3A illustrates an exemplary perspective view of the parabolic reflector. FIGs. 3B and 3C illustrate exemplary front view and sectional view of the parabolic reflector respectively. In an embodiment, the parabolic reflector 300 can include a cavity 302 surrounded by a tapered surface 304. The tapered surface 304 can be bound by a taper angle of 111.49° with a longitudinal surface of the parabolic reflector 300.

[0061] In an embodiment, the parabolic reflector 300 can shape the incoming wavefront generated by the piezo crystal arranged at a location in vicinity of focal area of the parabolic reflector 300. In an embodiment, the parabolic reflector 300 can assist in modulation of transmission beam angle of the incoming wavefront beams by adjusting focal length of the parabolic reflector.

[0062] FIG. 4A illustrates an exemplary side view of the ultrasonic transducer emitting a donut shaped/toroidal energy wavefront in accordance with an embodiment of the present disclosure. FIG. 4B illustrates an exemplary perspective view of the ultrasonic transducer emitting the donut shaped/toroidal energy wavefront in accordance with an embodiment of the present disclosure. In an embodiment, the ultrasonic transducer 400 can include a wave shaping and scattering unit to shape the incoming wavefront in order to obtain multi frequency sweeping energy waves having ultrasound waves encapsulating sonic waves.

[0063] In an embodiment, the wave shaping and scattering unit can attenuate and shape the incoming wavefront to obtain a multi-beam and multi-directional energy wavefront. In an embodiment, the wave shaping and scattering unit can include a wave sheer grill 100 that can scatter the incoming wavefront as to convert the incoming wavefront into multi -direction energy wavefront that are in the form of the donut shaped/toroidal energy wavefront 402. In an embodiment, the wave sheer grill 100 can slice the incoming wavefront at appropriate grill angles.

[0064] In an embodiment, the ultrasonic transducer 400 can emit the multi-beam and multi-directional donut shaped/toroidal energy wavefront 402 that includes multi -directional low frequency ultrasound carrier sweep with an encapsulated multi-directional sonic frequency sweep having frequency ranges that covers natural resonant frequency range of human body as a whole as well as at cellular level in order to effective stimulate and/or module cell metabolism of the human body.

[0065] It would be appreciated that the energy wavefront 402 generated by the proposed ultrasonic transducer 400 can be used for medical as well as non-medical applications, for example, for non-destructive testing of various materials that utilizes energy waves, such as ultrasound waves and sonic waves, to detect defects and/or anomalies in the materials.

[0066] FIG. 5 illustrates an exemplary representation of the donut shaped/toroidal energy wavefront emitted from the ultrasonic transducer in accordance with an embodiment of the present disclosure. In an aspect, the donut shaped/toroidal energy wavefront402includes multi-directional low frequency ultrasound carrier sweep with an encapsulated multi directional sonic frequency sweep. The sonic waves are encapsulated with the ultrasound waves such that frequency ranges of the ultrasound waves and the encapsulated sonic waves can confer with the natural resonant frequency of human body as a whole as well as at cellular level in order to effective stimulate and/or module cell metabolism of the human body with the help of the ultrasonic vibrations generated thereof.

[0067] In an embodiment, sonic waves are beneficial in stimulating bodily functions at organ and cell level. However, use of sonic waves in medical applications is confined as they do not have the ability to penetrate deep tissue. On the contrary, low intensity and low frequency ultrasound waves have deeper penetration than sonic waves. Hence, encapsulation of sonic waves with ultrasound carrier allows the sonic waves to piggy back on the ultrasound carrier. In addition, the ultrasound carrier also assists in cellular/organ revitalization to enhance operational capability of the medical application, for example, engulfing a subject being treated with the generated donut shaped/toroidal energy waves from all directions.

[0068] In an embodiment, the wave shaping and scattering unit of the ultrasonic transducer 400 can be configured to modulate parabolic spin angle of the energy wavefront. In an embodiment, the wave shaping and scattering unit can further be configured to block at least a portion of the incoming wavefront and the standing waves and to modulate of the donut shaped/toroidal incoming wavefront. In an embodiment, the wave shaping and scattering unit is further configured to slice of the donut shaped/toroidal incoming wavefront at appropriate grill angles.
