摘要： A system and method for controlling the delivery of ultrasound energy to a subject is provided. In particular, such a system and method are capable of safely disrupting the blood-brain barrier. Ultrasound energy is delivered to produce cavitation of an ultrasound contrast agent at a selected pressure value. An acoustic signal is acquired following cavitation, from which a signal spectrum is produced. The signal spectrum is analyzed for the presence of harmonics, such as subharmonics or ultraharmonics. When subharmonics or ultraharmonics are present, the pressure value is decreased for subsequent sonications. If a previous sonication resulted in no subharmonics or ultraharmonics being generated, then the pressure value may be increased. In this manner, the blood-brain barrier can be advantageously disrupted while mitigating potentially injurious effects of the sonication.

摘要： Systems and methods for accurately measuring changes in biomarker sensitive hydrogel volume and shape due to exposure to various biomarkers include a system for identifying one or more dimensional changes in a biomarker sensitive hydrogel positioned within an in vivo environment. The system includes a biomarker sensitive hydrogel positioned within an in vivo environment and configured to dimensionally change in response to interaction with predefined biomarkers. The system additionally includes an ultrasound transducer for locating and identifying one or more characteristics of the biomarker sensitive hydrogel and a computer system in electrical communication with the ultrasound transducer. The computer system is configured to receive characteristics of the biomarker sensitive hydrogel from the ultrasound transducer and determine dimensional changes of the biomarker sensitive hydrogel based on the received characteristics.

摘要： Systems and techniques for real-time, transcranial monitoring of safe blood-brain barrier opening include determining an approach angle for targeted blood-brain barrier opening proximate a predetermined region in a brain of a patient, and positioning an ultrasound transducer to generate a focused ultrasound signal at the determined approach angle to the predetermined region in the brain.

摘要： 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.

摘要： The inventions provided herein relate to tissue markers and uses thereof, e.g., to mark a target tissue site (e.g., a biopsy site in a breast tissue) or to produce a cell scaffold. The tissue markers described herein are designed to be resistant to fast migration (e.g., immediate migration after implantation through a needle track) and slow migration (e.g., over an extended period of time) upon implantation at a target tissue site (e.g., a biopsy site in a breast tissue), without using an adhesive. Additionally or alternatively, the tissue markers described herein can be readily detectable by at least one imaging modality, e.g., but not limited to magnetic resonance imaging, X-ray imaging, ultrasound imaging, or a combination thereof.

摘要： The disclosure relates to a method for automatically recognizing liver tumor types in ultrasound images. The method specifically comprises: using a plurality of Regions of Interest (ROIs) to represent a CEUS image; different lesions are distinguished by the performance and changes of the ROI in time and space; representing a space-time relationship between ROIs by establishing a model in time and space at the same time; and determining, by the model, a relatively appropriate ROI and relevant parameters of the model according to existing CEUS lesion samples by means of an iterative learning method. After giving a sample, an appropriate ROI can be determined and a reference diagnosis for the lesion can be given by removing part of inappropriate ROIs in advance and by means of a rapid search method.
