Abstract: The present invention proposes an ultrasound imaging system and method for measuring a property of a region of interest in a subject by using shear wave, wherein an ultrasound probe is configured to sequentially transmit, to each of a plurality of focal spots (320, 322, 324) in the region of interest, a push pulse (310, 312, 314) for generating a shear wave (330, 332, 334), each of the plurality of focal spots having a mutually different depth value (z1, z2, z3), and to receive ultrasound echo signals adjacent (350, 352, 354) to each of the plurality of focal spots; a shear wave detector is configured to derive, for each of the plurality of focal spots, a first parameter indicating a property of the generated shear wave, based on the received ultrasound echo signals; and a property estimator is configured to estimate a second parameter indicating the property of the region of interest as a function of the derived first parameters.

Abstract: Individual computer diagnostic support (CDS) systems are coupled to a ‘global’ CDS system, each of the CDS systems using the same learning system or the same learning system technique. Training and testing cases from each of the individual CDS systems are provided to the global CDS system, and the global CDS system uses these training cases to produce learning system parameters based on the training cases. Having more training cases than any of the individual CDS systems, the parameters provided by the global CDS system offer a higher quality diagnostic output than any of the individual CDS systems. The learning system parameters at the global CDS system may be provided to each of the individual CDS systems, to update the parameters of the individual CDS systems' learning system. The global CDS may also refine and/or adjust the structure of the embodied learning systems.

Abstract: The present invention provides a method and a system for medical imaging and information display. According to an aspect of the present invention, there is proposed a method of medical imaging and information display, comprising: acquiring imaging data of each point of a plurality of points in an imaging plane or imaging volume of a subject in each mode of a plurality of different imaging modes of a medical imaging apparatus; deriving, for said each point, a value by applying the imaging data of the point in said each mode and the imaging data of at least one other point of said plurality of points adjacent to the point in said each mode to a predetermined model, wherein the predetermined model is selected in accordance with a clinical medical application related to the subject; constructing an image based on all the derived values; and displaying the constructed image to a user. Accordingly, the novel method of medical imaging and information display may reduce the burden of doctors, and provide them with an image with a higher definition compared to the conventional ROI method.

Abstract: The present invention provides an ultrasound imaging system and an ultrasound imaging method for improving the imaging quality of the desired imaging plane in the volume of interest of a subject. According to the present invention, it is possible to directly scan the desired imaging plane by exploiting the capability of a 2D matrix ultrasound transducer and/or the flexibility of the position/orientation of the ultrasound probe. In some cases, the setting parameters of the transducer elements can be adjusted so that the ultrasound signal transmitted from the transducer elements is able to derive ultrasound echo data of the desired imaging plane without moving the probe. In other cases where the desired imaging plane cannot be directly scanned without changing the position/orientation of the ultrasound probe, the position/orientation of the ultrasound probe can be adjusted by means of user interaction, namely by outputting the instruction for guiding the user to move the probe so as to enable direct scanning of the desired imaging plane. In this way, the image of the desired imaging plane is not reconstructed by interpolation of the ultrasound echo data of the plurality of scanning planes (which are determined by the setting parameters of the transducer elements), but instead it is reconstructed from the ultrasound echo data of the desired imaging plane itself. In other words, the desired imaging plane is directly scanned. Thus, the image quality of the desired imaging plane is improved and may help doctors conduct a more accurate diagnosis.
Abstract translation: 本发明提供一种超声成像系统和超声成像方法，用于改善对象体感兴趣的所需成像平面的成像质量。 根据本发明，可以通过利用2D矩阵超声波换能器的能力和/或超声波探头的位置/取向的灵活性来直接扫描期望的成像平面。 在一些情况下，可以调整换能器元件的设定参数，使得从换能器元件发送的超声波信号能够导出所需成像平面的超声波回波数据，而无需移动探头。 在不改变超声波探头的位置/姿势的情况下，不能直接扫描所需成像平面的其他情况下，可以通过用户交互来调整超声波探头的位置/方向，即通过输出用于引导用户的指令 移动探头，以便能够直接扫描所需的成像平面。 以这种方式，通过对多个扫描平面（由换能器元件的设定参数确定）的超声波回波数据的内插来重建所需成像平面的图像，而是从超声波回波 所需成像平面本身的数据。 换句话说，直接扫描期望的成像平面。 因此，期望的成像平面的图像质量得到改善，并且可以帮助医生进行更准确的诊断。

Abstract: The present invention proposes an ultrasound imaging system and a method of calculating a perfusion parameter ratio. The proposed approach comprises: acquiring a time intensity curve of a contrast agent for each region unit of a plurality of region units of an imaging region of a subject, each region unit comprising one or more points of the imaging region; selecting, among the plurality of region units, a first, second and third sets of region units respectively corresponding to normal tissue, vessel and background noise, based on the time-intensity curves; calculating a perfusion parameter for each of one or more region units of the first set of region units and a perfusion parameter for a region of interest in the imaging region based on the calculated time-intensity curves; calculating a reference perfusion parameter based on the perfusion parameters of the one or more region units; and calculating a ratio value for the region of interest as a ratio of the perfusion parameter of the region of interest and the reference perfusion parameter. Since the reference perfusion parameter is calculated based on the one or more region units which are automatically selected, the approach requires no manual manipulation and the calculated perfusion parameter ratios are independent of operator experience.

Abstract: The present invention proposes an apparatus and method for characterizing a tissue in a first region of a subject. The apparatus comprises a receiving unit (210) for receiving ultrasound data of the tissue in the first region and ultrasound data of a predetermined target reference tissue of said subject; a deriving unit (220) for deriving a subject-specific model of the target reference tissue on the basis of the ultrasound data of the target reference tissue; and a characterizing unit (230) for determining a match between tissue in the first region and the target reference tissue on the basis of the subject-specific model and ultrasound data of the tissue in the first region. Unlike conventional tissue characterization based on a large cohort of patient data, the proposed subject-specific model is personalized for the specific subject without any generalization, resulting in higher sensitivity and/or accuracy. Preferably, the subject-specific model of the target reference tissue is derived on the basis of both the ultrasound data of the target reference tissue and the ultrasound data of a background reference tissue of a different type than the target reference tissue.
