摘要： Photon-based radiosurgery is widely used for treating local and regional tumors. The key to improving the quality of radiosurgery is to increase the dose falloff rate from high dose regions inside the tumor to low dose regions of nearby healthy tissues and structures. Dynamic photon painting (DPP) further increases dose falloff rate by treating a target by moving a beam source along a dynamic trajectory, where the speed, direction and even dose rate of the beam source change constantly during irradiation. DPP creates dose gradient that rivals proton Bragg Peak and outperforms Gamma Knife® radiosurgery.
摘要翻译：基于光子的放射外科手术广泛用于治疗局部和局部肿瘤。提高放射外科手术质量的关键是提高肿瘤内部高剂量区域到附近健康组织和结构的低剂量区域的剂量衰减率。动态光子绘画（DPP）通过沿着动态轨迹移动光束源来处理目标物体进一步增加剂量衰减速率，其中光束源的速度，方向和均匀剂量率在照射期间不断变化。 DPP产生与质子Bragg峰值相当的剂量梯度，并优于GammaKnife®放射外科手术。

摘要： Provided are a radiography device, a radiography method, and a radiography program which can obtain an accurate radiographic image while reducing a burden on a subject. A radiography device control unit determines imaging conditions including at least one of resolution or an incident angle range, on the basis of a radiographic image captured before tomosynthesis imaging, and performs tomosynthesis imaging. Specifically, the radiography device control unit controls tomosynthesis imaging (120) such that tomosynthesis imaging is performed under first conditions (108) of low resolution and a narrow incident angle range in a case in which a mutation site suspected as a lesion is not detected and tomosynthesis imaging is performed under second conditions (112, 116, and 118) which are different from the first conditions in at least one of the resolution or the incident angle range in a case in which the mutation site suspected as a lesion is detected.

摘要： Cone Beam Breast CT (CBBCT) is a three-dimensional breast imaging modality with high soft tissue contrast, high spatial resolution and no tissue overlap. CBBCT-based computer aided diagnosis (CBBCT-CAD) technology is a clinically useful tool for breast cancer detection and diagnosis that will help radiologists to make more efficient and accurate decisions. The CBBCT-CAD is able to: 1) use 3D algorithms for image artifact correction, mass and calcification detection and characterization, duct imaging and segmentation, vessel imaging and segmentation, and breast density measurement, 2) present composite information of the breast including mass and calcifications, duct structure, vascular structure and breast density to the radiologists to aid them in determining the probability of malignancy of a breast lesion.

摘要： A system for dental implant restoration is provided. It includes universal aligning adaptors and prosthetic components having co-operable indices, which together form a translational, integrating system which aligns, synchronizes, and references the prosthetic components about an implant's central axis of rotation. Rotation of an adaptor about a prosthetic component, with its reference point becoming aligned to a predetermined reference point on the prosthetic component, followed by the rotation of the adaptor/prosthetic component assembly about the implant, situates the prosthetic component in a predetermined position such that all other prosthetic components become synchronized to the adaptor's reference point. The prosthetic component is mechanical for clinical or lab bench use, or is virtual for restoration design in a software program, prior to milling prosthetic abutments or devices. Abutments, healing caps and screw access holes are realigned to preferred positions and synchronized with minimal deviation from the ideal direction.

摘要： Disclosed is a rotating-grating cone beam CT imaging apparatus. This imaging apparatus is composed of a frame, a frame angle sensor, an X-ray source equipped with a rotating grating, a flat panel detector, a main controller and an image reconstruction workstation. Like a general cone beam CT imaging apparatus, this imaging apparatus also adopts an open structure. But unlike the general cone beam CT imaging apparatus, the rotating grating limits X-rays emitted from the X-ray source to a plurality of narrow-angle cone beams or sector beams. In the process that the X-ray source and the detector rotate around an imaging object, projection images of the narrow-angle cone beams or sector beams on the flat panel detector move back and forth continually through the rotation of the rotating grating, so as to acquire projection information about the imaging object in an entire scanning region. Finally, the projection information is reconstructed into a volume image in the image reconstruction workstation. In this manner of variable-focus scanning, the present invention not only can reserve the advantage of the open structure of the cone beam CT imaging apparatus, but also obtains the advantage that a sector beam CT imaging apparatus can restrain scattered photons so as to generate a high-quality image.
摘要翻译：公开了一种旋转光栅锥束CT成像装置。该成像装置由框架，框架角度传感器，配备有旋转光栅的X射线源，平板检测器，主控制器和图像重构工作站构成。像通用锥形束CT成像装置一样，该成像装置也采用开放结构。但是，与通用锥形束CT成像设备不同，旋转光栅将从X射线源发射的X射线限制到多个窄角锥形束或扇形光束。在X射线源和检测器围绕成像物体旋转的过程中，平面板检测器上的窄角锥形束或扇形光束的投影图像通过旋转光栅的旋转而不断地前后移动，因此以在整个扫描区域中获取关于成像对象的投影信息。最后，将投影信息重建为图像重建工作站中的体积图像。以这种可变焦点扫描的方式，本发明不仅可以保留锥形束CT成像装置的开放结构的优点，而且可以获得如下优点：扇形束CT成像装置可以抑制散射的光子以产生高质量的图像。

摘要： Systems, methods, and related computer program products for image-guided radiation treatment (IGRT) are described. Provided according to one preferred embodiment is an IGRT apparatus including a barrel-style rotatable gantry structure that provides high mechanical stability, versatility in radiation delivery, and versatility in target tracking. Methods for treatment radiation delivery using the IGRT apparatus include conical non-coplanar rotational arc therapy and cono-helical non-coplanar rotational arc therapy. A radiation treatment head (MV source) and a treatment guidance imaging system including a kV imaging source are mounted to and rotatable with a common barrel-style rotatable gantry structure, or alternatively the MV and kV sources are mounted to separate barrel-style rotatable gantry structures independently rotatable around a common axis of rotation. Methods for intra-fraction target tracking in a gantry-style IGRT system based on comparisons between a pre-acquired planning image and intrafraction x-ray tomosynthesis images and/or intrafraction cone beam CT (CBCT) images are also described.

摘要： In order to provide a technique of obtaining an image having high diagnosability without degrading the operability in an X-ray CT apparatus that suppresses the amount of exposure of an object by controlling the amount of radiation by setting a target image SD and determining the imaging conditions (tube current) satisfying the target image SD, there is provided an X-ray CT apparatus that controls the amount of radiation according to the size of an object in consideration of the contrast by simply inputting one image quality level as a reference of the image quality level that the operator desires. The input image quality level is set as a target image SD when scanning an object having a standard size with a standard tube voltage.
