本发明涉及一种多超声通路成像系统，属于医疗器械技术领域。The invention relates to a multi-ultrasonic channel imaging system, which belongs to the technical field of medical devices.
背景技术Background technique
随着社会经济和医疗卫生条件的发展，由于超声技术带来的创口小、无辐射、并发症少等优点，越来越多的超声成像技术应用到了诊断治疗和监护，包括：1)血管内超声(intravenous ultrasound，IVUS)成像技术，使用超声显像技术和多普勒血流测定，显示心血管断面和血流；2)心腔内超声(IntraCardiac Echocardiography，ICE)成像技术，将超声探头置于心腔内部，以实现心脏解剖结构、心脏血流动力学、心脏功能等信息的实时成像；3)彩超(Color ultrasound)技术，采用相控阵、线阵、凸阵、机械扇扫、三维探头、内窥镜探头等各种形式换能器，采集血流运动、组织运动信息和人体器官组织成像，包括但不限于TCD(TransCranial Doppler，经颅多普勒超声)、TTE(Trans-Thoracic Echocardiography，经胸超声心动图)等。With the development of social economy and medical and health conditions, due to the advantages of small wounds, no radiation, and fewer complications brought by ultrasound technology, more and more ultrasound imaging technologies have been applied to diagnosis, treatment and monitoring, including: 1) Intravascular Ultrasound (intravenous ultrasound, IVUS) imaging technology, using ultrasound imaging technology and Doppler blood flow measurement, to display cardiovascular section and blood flow; 2) IntraCardiac Echocardiography (ICE) imaging technology, placing the ultrasound probe inside the heart chamber to realize real-time imaging of cardiac anatomical structure, cardiac hemodynamics, cardiac function and other information; 3) Color ultrasound (Color ultrasound) technology, using phased array, linear array, convex array, mechanical sector scan, three-dimensional Various forms of transducers such as probes and endoscopic probes can collect blood flow movement, tissue movement information and human organ tissue imaging, including but not limited to TCD (TransCranial Doppler, transcranial Doppler ultrasound), TTE (Trans-Thoracic Echocardiography, transthoracic echocardiography) and so on.
IVUS主要应用于血管疾病诊断和介入治疗，尤其是应用于冠状动脉系统。包括治疗造影不能明确诊断的病例；明确病变形态和斑块性质；评价病变长度，显示支架位置；评价冠状动脉介入治疗疗效。ICE已被应用于房颤射频消融术、左心耳封堵术、房间隔缺损封堵术、二尖瓣成形术、心内膜心肌活检术等多种手术。彩超的超声成像、测量与血流运动信息采集供临床诊断检查使用，其中探头可血管内、术中经人体内部组织，和/或用于超声导航等领域。IVUS is mainly used in the diagnosis and interventional therapy of vascular diseases, especially in the coronary artery system. Including the treatment of cases that cannot be clearly diagnosed by angiography; clarifying the shape of the lesion and the nature of the plaque; evaluating the length of the lesion and showing the position of the stent; evaluating the efficacy of coronary intervention. ICE has been applied in various surgeries such as atrial fibrillation radiofrequency ablation, left atrial appendage closure, atrial septal defect closure, mitral valve annuloplasty, and endomyocardial biopsy. Ultrasonic imaging, measurement and blood flow movement information collection of color Doppler ultrasound are used for clinical diagnosis and examination, in which the probe can be used in blood vessels, through internal tissues of the human body during surgery, and/or for ultrasound navigation and other fields.
鉴于超声技术无辐射、超声探头形式多样、多种指标精确测量等众多优点，不同超声技术融合以及与其他技术的融合也逐渐得到更广泛的应用。比如IVUS与OCT(OpticalCoherence tomography，光学相干断层扫描技术)融合，充分发挥IVUS的高穿透深度和OCT高分辨的优点，更精确的指导冠状动脉介入治疗。In view of the many advantages of ultrasound technology, such as no radiation, various types of ultrasound probes, and accurate measurement of multiple indicators, the fusion of different ultrasound technologies and the fusion with other technologies have gradually been more widely used.

目前的超声成像系统大多是单一超声通路的形式，超声通路由一个超声换能组件形成，超声换能组件包括接入患者体内的超声导管以及设置于超声导管内的超声换能装置，例如IVUS成像导管，或者包括位于患者体外的探头以及设置于探头上的超声换能装置，例如TTE成像探头装置，而对于不同超声技术进行融合的技术还不多，尤其缺失关于IVUS与彩超/ICE融合技术，从而造成各自优点没有得到更充分的应用；同时医院需要为不同的应用场景采购更多的种类的设备造成成本的增加和资源的浪费。Most of the current ultrasonic imaging systems are in the form of a single ultrasonic channel. The ultrasonic channel is formed by an ultrasonic transducer assembly. Catheters, or probes located outside the patient's body and ultrasonic transducers installed on the probes, such as TTE imaging probe devices, but there are not many technologies for fusion of different ultrasound technologies, especially the lack of IVUS and color Doppler ultrasound/ICE fusion technology, As a result, their respective advantages have not been fully utilized; at the same time, hospitals need to purchase more types of equipment for different application scenarios, resulting in increased costs and waste of resources.

在本发明中，彩超包括但不局限于2维彩超、3维彩超、4维彩超等各种维度彩超；可以使用的探头包括但不限于相控阵、线阵、凸阵、机械扇扫、三维探头、内窥镜探头等类型探头；根据使用对象包括但不限于TCD(TransCranial Doppler，经颅多普勒超声)、TTE(Trans-Thoracic Echocardiography，经胸超声心动图)等。IVUS功能模式包括但不限于2D模式、3D渲染或者造影融合等IVUS功能模式。ICE功能模式包括但不局限于B模式、C模式、M模式、3D模式、4D模式和造影融合等ICE功能模式。In the present invention, color Doppler ultrasound includes but not limited to 2D color Doppler ultrasound, 3D color Doppler ultrasound, 4D color Doppler ultrasound and other dimensional color Doppler ultrasound; probes that can be used include but are not limited to phased array, linear array, convex array, mechanical sector scan, Three-dimensional probes, endoscopic probes and other types of probes; including but not limited to TCD (TransCranial Doppler, transcranial Doppler ultrasound), TTE (Trans-Thoracic Echocardiography, transthoracic echocardiography) etc. according to the target. IVUS functional modes include but not limited to 2D mode, 3D rendering, or imaging fusion and other IVUS functional modes. ICE functional modes include but are not limited to ICE functional modes such as B mode, C mode, M mode, 3D mode, 4D mode, and contrast fusion.
显然，上述实施例仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引申出的显而易见的变化或变动仍处于本发明创造的保护范围之中。Apparently, the above-mentioned embodiments are only examples for clear description, rather than limiting the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. However, the obvious changes or changes derived therefrom are still within the scope of protection of the present invention.
