Definitions
- Various embodiments relate to an ultrasound system and methods for creating an ultrasound image.
- various devices and methods can be used to image the oral cavity of a human or animal and its surrounding anatomical structures, such as for diagnosing soft and hard tissue pathological changes within this region.
- classic imaging methods e.g. dental film, OPG, DVT, CT and MRI are used.
- Imaging methods based on ionizing radiation may, for example, be limited in their application (e.g. due to pregnancy, claustrophobia), only enable a selective detailed display (e.g. mainly hard tissue display), and/or involve radiation exposure (or radiation dose exposure) for the be connected to patients.
- Imaging methods based on magnetic resonance imaging can, for example, be limited in their application (e.g. due to pacemaker(s), claustrophobia), only allow a selective display of detail (e.g. mainly soft tissue imaging), and/or be very time-consuming.
- the accuracy of the impression may be limited by a material and/or by a practitioner.
- a system can be provided that enables non-invasive measurement of 3D objects in the area of the oral cavity of a human and/or an animal.
- the system can be easy to handle for a user, and/or have a high image resolution and/or have increased resistance to (measurement) artifacts compared to conventional systems.
- the system enables live imaging, which enables a high level of flexibility and readjustment with regard to the imaged volume.
- the system can be suitable for enabling three-dimensional representation and measurement of jaw clefts.
- the system can make it possible to fully display the (sometimes very complex) geometries of jaw clefts. This can support optimal planning of a split osteoplasty.
- the system can be used during follow-up treatment of patients who have already been treated (e.g. after surgery) in order to better and more closely monitor the healing process. The system can therefore enable the healing process to be supplemented by suitable therapies, for example.
- a non-invasive measurement methodology can be provided, which can be based on ultrasound (also referred to as sonography) for recording three-dimensional images and for measuring the oral cavity and directly adjacent structures (e.g. anatomical physiological and/or pathological structures).
- ultrasound also referred to as sonography
- directly adjacent structures e.g. anatomical physiological and/or pathological structures
- one or more ultrasound measurement reference points can be placed within the oral cavity.
- a fixed reference system for precise ultrasound measurement can be implemented in the oral cavity using a bite splint.
- the oral cavity can then be filled with a suitable (filling) medium.
- a suitable (filling) medium can be understood to mean, for example, a medium that is suitable for conducting ultrasonic waves within (e.g. has a low absorption of ultrasonic waves within the oral cavity) and can be introduced safely into the oral cavity (e.g. is not toxic).
- a suitable medium can be, for example, water.
- an ultrasonic transducer e.g. an ultrasonic sensor
- the ultrasound transducer can be placed within the oral cavity.
- the ultrasound transducer can be placed outside the oral cavity.
- the ultrasound transducer can be placed on the floor of the mouth from below.
- the ultrasonic transducer can thus be set up to generate a first ultrasonic wave within the oral cavity that corresponds to a first ultrasonic signal (ie an excitation signal).
- the ultrasound transducer can be set up to detect (eg receive) a second ultrasound wave (eg a reflection of the first ultrasound wave) and to generate a second ultrasound signal (ie a measurement signal) corresponding to the second ultrasound wave.
- the second ultrasound signal can, for example, contain information about the oral cavity and/or the bite splint, in order to create a 3-dimensional To take an image of a target region within the oral cavity (e.g. the palate) and/or adjacent to the oral cavity (e.g. the floor of the mouth).
- a bite splint or brace may be provided for insertion into the oral cavity.
- one or more reference points can be attached to/in the bite splint for calibrating an ultrasonic sensor and/or for correcting the measurement data.
- a bite splint can be used as part of an ultrasound measurement of the oral region.
- one or more reference points can be provided in the oral cavity, for example in order to carry out calibration and/or error correction of the determined (e.g. recorded) ultrasound signals (e.g. in the form of ultrasound measurement data).
- one or more ultrasonic transducers may be attached in and/or to the bite splint.
- the one or more ultrasonic transducers can, for example, be mounted firmly and/or movably within the bite splint.
- the one or more ultrasonic transducers can be integrated in and/or on the bite splint. This can, for example, reduce representation uncertainty, e.g. of the teeth or tongue, due to the more direct measurement.

- the one or more external ultrasound transducers can be guided around and/or attached to the patient's head from the outside.
- the one or more external ultrasound transducers can sound through the floor of the mouth from below and thus an ultrasound wave, which corresponds to an ultrasound signal, can be generated in an oral cavity.
- This allows flexible imaging of the oral cavity and its adjacent structures from different recording positions. Potentially arising measurement artifacts (or disturbances) can be characterized and eliminated, for example, using the reference points. This can increase the resolution when imaging through the floor of the mouth.
- one or more ultrasound transducers may be used to create and/or measure an ultrasound image of an entire oral cavity and/or its adjacent (soft tissue) structures.
- the one or more Ultrasonic transducers can be applied to the oral cavity from the outside (e.g. from below to the floor of the mouth).

- an ultrasonic wave can be (at least) partially deflected (e.g. reflected) and/or partially transmitted at interfaces between two adjacent substances.
- the respective deflected or transmitted portion depends on an impedance difference at the interface of the two neighboring substances.
- an incident ultrasonic wave can be strongly deflected (e.g. more than 10%, 25%, 50%, 75% or more than 95%).
- this difference can be particularly pronounced between a gas (e.g. air) and a liquid (e.g. water).
- a filling medium that prevents the formation of air bubbles can be used.
- the filling medium can be used to fill a cavity filled with a gas. Ultrasonic wave guidance within the cavity can thus be enabled.

- a smaller reduction in the signal strength of the ultrasonic wave can lead to better quality of the corresponding measurement data.
- an ultrasonic wave can generally be attenuated when passing through a medium, i.e. an intensity (e.g. radiation intensity) of the wave can decrease.
- an incoming wave when striking an interface, can be transmitted through the interface and reflected at the interface. Absorption of the wave takes place primarily in the volume of the respective medium and therefore absorption (if it occurs) can be neglected.
