Definitions

  • the present invention relates to an ultrasound imaging probe for use in ultrasound guided interventional procedures including regional anaesthesia.
  • the physical gap for the needle to pass though must also be kept to a minimum, and this reduces possible articulation in the gap with the probe in place.
  • Curved arrays may allow a more direct entry of the needle but are not generally available in a suitable frequency and for other reasons may not offer optimum imaging or other features.
  • Each probe functions as a normal linear (1 D) array with a corresponding gap in the image. There is minimal overlap in the acoustic image from the two blocks of elements as all elements exist on the same linear plane. The direction/plane of propagation of each block of elements is identical.
  • US Patent 6423002 by J.A. Hossack, entitled “Intra-operative diagnostic ultrasound multiple-array transducer probe and optional surgical tool” and US Patent 7214191 by B. Stringer and G. Simmons entitled “Multiplanar ultrasonic vascular imaging device, system incorporating same, method of use and protective sheath,” are probes where at least two individual blocks of elements are arranged onto the same 2D plane and lie perpendicular to each, i.e. in a T- shape. Each block of elements produces an individual image which can be viewed adjacent to each other or in pseudo (wrap-around) 3D, on-screen.
  • the angled element is not an array. Although it is defined as comprising of at least one element, it has only one element in cross section along the plane of the adjacent array.
  • the arrays described are 2 dimensional, i.e. each is arranged in a grid of elements, in this case 2 x 4 elements with only 2 elements in lateral section.
  • the probe is connected to a shaped waveguide for mounting to steel.
  • the intended aim is to improve beam focusing rather than provide an overlapping visual image area.
  • an ultrasound probe comprising a pair of transducer modules arranged in-line and spaced apart from each other to form a shallow "V" shape in a defined range of angles which correspond to ergonomic conformity to a patient's body surface at procedure specific locations such as to allow a full ultrasound image of a target depth through an ultrasound scan engine.
  • the ultrasound probe is shaped to conform to the body surface of the majority of patients over the areas of the neck, axilla, forearm, lower leg, chest wall, knee and other joints.
  • the angle between each front plane of the twin arrays is angled between 1 10 ° and 140 °, conforming to the respective part of the body being imaged.
  • the ultrasound probe preferably provides a gap for needle manipulation through the center of the two arrays of between 2mm and 15mm.
  • the ultrasound image is created through a recombination of waveform data obtained from the separate arrays by treating the twin angled arrays as one virtual array, using respective delays and angular realignment of the individual transmit and receive channels to create one continuous visual image.
  • the ultrasound image creation includes the application of beam steering and RF signal compounding to the arrays to produce an improved visual image.
  • the recombination of waveform data is obtained from the separate arrays by capturing standard B-mode images from each array individually, rotating and positioning said images, using weighted pixel selection and overlapping visual gain mixing to create one cohesive image.
  • the arrays may be straight linear arrays or curved.
  • the ultrasound probe may be shaped to allow ergonomic manipulation possibilities for an operator.
  • a third array may be provided arranged perpendicular to the plane of the first pair, at a similar angle thereto and also in-plane with a needle entry area, which adds a concurrent 2D image to the combined image.
  • a second aspect of the present invention there is provided a method of carrying out ultrasound guided regional anaesthesia using an ultrasound probe in accordance with a first aspect of the invention.
  • Figure 1 is a representation of the layout and operating range of an ultrasound probe according to an embodiment of the present invention having flat arrays;
  • Figure 2 is a front view of an ultrasound probe similar to that of Fig 1 arranged to provide an expanded field of view;
  • Figure 3 is a corresponding view to Fig 1 illustrating the layout and operating range of an ultrasound probe having curved arrays;
  • Figure 4 is a perspective view from below of an ultrasound probe in accordance with the present invention.
  • Figure 5 is a front perspective view from above of the ultrasound probe of Fig 4;
  • Figure 6 is a perspective view from below of an alternative embodiment of an ultrasound probe in accordance with the present invention.
  • Figure 7 is a representation of the visual display resulting from use of an ultrasound probe as exemplified in Figs 1 -5; and Figure 8 is a representation of the visual display resulting from an ultrasound probe as exemplified in Figure 6.
  • an ultrasound probe 10 of the present invention comprises a pair of one dimensional transducer modules 1 , 2, arranged in-line but set apart from each other in a shallow "V" shape. This allows a wide gap for needle manipulation while maintaining the ability to compute a good acoustic image of the target area 4 on the ultrasound scan engine.
  • the ultrasound image is a product of data from both the arrays.
  • the concept can be applied to linear arrays as shown in Fig 1 , or for a wider field of view 5, using expanded field of view algorithms as in Fig 2 or a pair of curved linear arrays 1 a, 2a as in Fig3.
  • the probe 10 is shaped to allow ergonomic manipulation possibilities for the anaesthetist.
  • the probe can be held in a 'pencil-type' grip anywhere on the main body, or by pushing directly on the back of arrays.
  • the shape of the probe which can best be seen in Figs 2, 4 & 5 means it sits in position better on a patient than a conventional probe.
  • a further option is the addition of a third array 1 1 arranged perpendicular to the plane of the twin pair and in-plane with the needle entry 20 as shown in Fig 6; this gives a secondary in-plane view of the target area and needle point .
  • the third array is set at a similar angle to the others.
  • a visual display will be constructed using the data from both array modules, combined with scan engine processing to form one cohesive image 21 covering the extent of the acoustic beam width of the probe as can be seen in Fig 7.
  • a third array image 22 will be displayed side by side with the combined image 21 from the twin arrays as can be seen in Fig 8.
  • the image reconstruction for the combined view can be performed either through visual mixing of the independent images from each array or by forming one visual image through the interpretation of transmit and receive signals to represent one virtual curved or linear array.
  • the ultrasound probe of the current invention has a number of advantages.
  • a pair of arrays are set apart and angled in a shallow 'V shape with overlapping beam area providing an ultrasound image.
  • the conformal shape of the device provides a more stable 'platform' for an anaesthetist.
  • the probe does not provide a 'needle guide' as such and the anaesthetist is free to work within an extended gap.
  • the probe may incorporate 'sparse' array beam forming to utilise the full width of all available array elements despite the limitations of the maximum number of independent channels that current circuitry can handle.

Abstract

La présente invention concerne une sonde à ultrasons (10) comportant une paire de modules de transducteurs unidimensionnels (1, 2) disposés en ligne mais espacés mutuellement en une forme en V peu profonde. Cela permet un grand espace pour la manipulation d'aiguille tout en maintenant la capacité de calculer une bonne image acoustique de la zone cible (4) sur un moteur de balayage à ultrasons. L'image ultrasonore est un produit de données provenant des deux réseaux. La sonde (10) est conformée pour permettre des possibilités de manipulation ergonomique pour l'anesthésiste. La sonde peut être tenue comme on tient un crayon sur toute partie du corps principal, ou en poussant directement sur l'arrière des réseaux. La forme de la sonde lui procure une meilleure assise sur un patient que celle d'une sonde classique.
