The present disclosure relates to the field of ultrasonic detection, in particular to a craniocerebral ultrasonic standard plane imaging and automatic detection and display method for abnormal regions. The following technical solution is adopted: contour detection is performed on the scanned ultrasound images the skull to construct a skull surface model, and the standard planes in ultrasound images are identified and extracted according to the skull surface model. The symmetry of the standard planes in ultrasound images is used to compare the similarity, so as to obtain the abnormal regions for segmentation and display. The advantages of the present disclosure are as follows: the skull surface model is constructed by detecting the cranial edge, and the coordinate system is established based on this model, thereby the standard planes in ultrasound images can be quickly identified from the scanned ultrasound images.

The disclosed subject matter related to methods and apparatus for determining brain swelling and brain shifting in a patient as well as predicting a possible resultant increase in intracranial pressure in the patient. The apparatus can include a transducer such as an ultrasound transducer communicatively connected to a controller via wires or via wireless communications device(s). A monitor and/or alarm device can be provided to notify a practitioner when the controller has determined brain swelling is occurring and/or when an imminent increase in intracranial pressure is likely to occur.

The three-dimensional ultrasound imaging method comprise emitting an ultrasonic wave to a fetal head; receiving an ultrasonic echo to acquire an ultrasonic echo signal; acquiring three-dimensional volume data of the fetal head according to the ultrasonic echo signal; detecting a median sagittal section from the three-dimensional volume data according to features of the median sagittal section of the fetal head; determining a facing orientation of the fetal head in the median sagittal section; displaying the median sagittal section as an image suitable for observation according to the facing orientation of the fetal head.

A system for delivering drugs or other molecules to the brain comprises an ultrasound imaging transducer configured to image structures such as the circle of Willis within a patient's head by way of a low attenuation acoustic window. The system includes a processor configured to register the ultrasound images to previously obtained images which also include the structures. The system includes ultrasound transducer elements operable to deliver ultrasound energy to a target region to cause the blood brain barrier to open. The system may include a drug delivery system that may be operated to deliver a drug to the patient in coordination with opening the blood brain barrier. Coordinates of the target region relative to the ultrasound imaging transducer are determined using registration information.

The invention relates to a method for obtaining a numerical model, the numerical model associating at least one objective measurement to a subjective sensation, the method comprising the steps of: a) imaging the at least one area of the brain by using unfocused waves produced by a transcranial ultrasound probe (20), to obtain at least one acquired image of the activity of the area, b) evaluating a physical quantity representative of the activity of the at least one area based on the acquired images, to obtain at least one objective measurement, c) obtaining from the subject at least one numerical value representative of a subjective sensation, and d) determining the numerical model by using the obtained objective measurement and the obtained numerical value.

A device is provided for diagnostic measurement by simultaneous multimodal analysis of a subject's head wherein the cerebral blood flow variations as well as the concentration level of oxygenation in the subject's blood are used to determine the presence and the pathophysiology of neurocognitive disorders, including the neurodegenerative disease referred to as Alzheimer's disease.

An ultrasound treatment system operable to deliver ultrasound energy to a patient's brain, the system comprises a treatment ultrasound transducer comprising a plurality of treatment elements, the treatment ultrasound transducer locatable to deliver ultrasound into the head of the patient. The system further comprises a data store, one or more position sensors configured to detect relative movement between the head of the patient and the treatment ultrasound transducer, and a data processor.

Arrangements described herein relate to a headset. The headset includes a device. The device includes a transducer configured to interact with a head of a subject. The headset further includes a manually-operated registration system configured to delineate a workspace of the transducer at the head of the subject.

The present invention provides monitoring of brain blood circulation in a patient with cardiac pacemaker for the prevention of symptoms associated with pacemaker syndrome and stroke. The monitoring of brain blood flow velocity is performed using a transcranial Doppler ultrasound device synchronized with an implanted cardiac pacemaker, to select the pacing mode that enhances cerebral perfusion in the patient. The system further detects microembolic signals in the cerebral circulation and triggers sonothrombolysis as well as release of thromolytic and neuroprotective agents for clot dissolution.
