一、RK-50：台式聚焦超声系统
Bench-top focused ultrasound
这一聚焦超声系统能够完成定向大脑暴露（开放血脑屏障），而不需要并发的成像。
RK-50是独立的能型临床前系统，可以利用聚焦超声的各种用途。通过传统的立体定位方法的使用，RK-50能够透过啮齿类动物大脑的头盖骨向细小的结构发射精确剂量的聚焦超声。该系统还能够自动栅格化一系列聚焦超声来覆盖任意大小的体积。其应用包括切除、血脑屏障毁坏和神经调制。
The focused ultrasound system that enables targeted brain exposures without the need for concurrent imaging.
The RK-50 is a stand-alone, versatile, preclinical system designed to take advantage of the various applications of focused ultrasound. Through the use of traditional stereotaxic targeting methods, the RK-50 can deliver precise doses of FUS through an intact skull to small structures in the rodent brain. The system can also be used to automatically raster a series of FUS exposures to cover an arbitrary volume. Applications include ablation, blood-brain barrier disruption, and neuromodulation.
Specifications:
Precise, fast targeting with 3-axis positioning system
Treatment planning software facilitates stereotaxic-guided target selection and exposure control (runs on included PC)
Multi-point targeting is achievable in line, raster, and circular exposures
Focused ultrasound dose settings can be easily controlled for any application
Utilizes calibrated focused ultrasound transducers, available in a range of frequencies
二、RK-100影像导航的聚焦超声系统
MRI-compatible image-guided focused ultrasound system
这一可兼容核磁共振成像的影像导航聚焦超声系统由一套电脑控制的高精度三维定位系统和高能的聚焦超声转换器组成。
定位系统能够地向毫米大小的区域输送聚焦超声能量到软组织。这一系统专门用于研究从小到大的动物模型，从而探究超声-组织相互作用，在用于人体之前评价治疗方法的安性，可匹配临床MR和CT扫描仪从而完成影像导航的治疗计划和递送。该系统完无磁性，因而可以与高场核磁成像仪共同工作，还可匹配X射线CT成像。
The MRI-compatible image-guided focused ultrasound system consists of a computer-controlled high-precision three-axis positioning system and a high-power focused ultrasound transducer coupled.
The positioning system enables delivery of focused ultrasound energy to precise locations in soft tissue. The system is designed specifically for research in small to large animal models to investigate ultrasound-tissue interactions, and to evaluate the safety of therapeutic approaches prior to translation into humans. The entire FUS system fits within the bore of a clinical MR or CT scanner for image-guided treatment planning and delivery. The system is completely non-magnetic, enabling it to function within a high-field magnetic resonance imager for image-guided treatment planning and monitoring of ultrasound exposures. In addition, the system is compatible with X-ray CT imaging as well.
lp-production-iso-in-bore
Inside every RK-100 is a custom-built and calibrated focused ultrasound transducer capable of exposing millimeter – size volumes of tissue within a subject.
The non-magnetic positioning system can translate the transducer along arbitrary 3D paths during imaging. The delivery of ultrasound exposures is achieved using images acquired with MRI or CT, depending on the configuration of the system. Real-time monitoring of forward and reflected electrical power to the transducer enables consistent delivery of energy during experiments.
The system is capable of delivering exposures ranging from high-power continuous sonications for thermal coagulation of soft tissues, to pulsed sonications suitable for applications such as tissue lysis, drug delivery, or vascular permeabilization. Since the system is designed for research it is designed to be flexible, offering users the capability to design their experiments to suit their needs.
三、RK-300小口径影像导航聚焦超声系统
RK-300专门设计针对小型动物模型，特别适用于血脑屏障毁坏研究，它包括影像导航定位软件，一台电脑控制的高精度两轴定位系统和校准的聚焦超声转换器。RK-300是世界上一款能够进行无创过高热、切除和血脑屏障开放等功能的临床前成像系统。
The RK-300 is a focused ultrasound system created to be used within small-bore preclinical imaging systems.
This platform is specifically designed for the exposure of small animal models and is particularly suited for blood brain barrier disruption studies. It includes image-guided targeting software, an integrated computer controlled high precision two-axis positioning system, and a calibrated focused ultrasound transducer. The RK-300 is the only system in the world capable of performing non-invasive hyperthermia, ablation and blood brain barrier opening within a small bore preclinical imaging system.
Specifications:
Calibrated focused ultrasound transducer offered in a range of frequencies from 750kHz to 5MHz fundamental frequency (custom focal lengths are available)
2-axis spatial positioning (20mm travel, 0.25mm precision)
Capable of pulsed and continuous ultrasound exposures
Image-based treatment planning software
Integrated RF surface coil
Compatible with bore sizes down to 70mm
