    • Fluoroscopic imaging of a patient's heart is performed by positioning a patient in a sterile field and imaging the heart using a x-ray fluoroscopy system within the sterile to produce a two-dimensional image. The two-dimensional image is simultaneously displayed on an operative display within or adjacent the sterile filed and on a display of a remote image processor outside the operative field. The two-dimensional image of the remote display is manually marked or annotated to show anatomical or treatment information which is simultaneously shown on the operative display. Alternatively, a patient's heart is imaged using a catheter to produce a real time image. The image is presented on a screen and sent to an image processor. Treatment parameters are input to the image processor, and the image processor calculates locations of a plurality of target treatment sites which are displayed on the screen. The catheter is advanced to position a treatment element on the catheter proximate a location of a target treatment site, where the actual position of the treatment element may differ from calculated location. After treating at the actual treatment position, an image processor calculates a difference between the positions of the calculated and actual treatment sites. The locations of all remaining target treatment may be recalculated by the image processor. Further alternatively, a patient's heart is imaged using a catheter to produce a real time image which is displayed on a screen. The image is also sent to an image processor where treatment parameters are input. The image processor then calculates safe regions and/or unsafe regions for performing a treatment or diagnosis within the heart based upon the inputted treatment conditions. The image processor superimposes information on the image on the screen to identify the safe and/or unsafe regions.
    • 患者心脏的荧光成像通过将患者置于无菌区域并使用无菌内的X射线透视系统对心脏进行成像来进行,以产生二维图像。 二维图像同时显示在无菌区域内或邻近无菌区域的操作显示器上,以及在操作区域外的远程图像处理器的显示器上。 手动标记或注释远程显示器的二维图像以显示同时显示在手术显示器上的解剖学或治疗信息。 或者,使用导管对病人的心脏成像以产生实时图像。 图像显示在屏幕上并发送到图像处理器。 治疗参数被输入到图像处理器,并且图像处理器计算在屏幕上显示的多个目标治疗部位的位置。 前进导管,将治疗元件定位在靠近目标治疗部位的位置处,其中治疗元件的实际位置可能与计算的位置不同。 在实际处理位置处理之后,图像处理器计算计算的和实际处理位置的位置之间的差异。 所有剩余目标处理的位置可以由图像处理器重新计算。 或者,使用导管对患者的心脏进行成像以产生显示在屏幕上的实时图像。 图像也被发送到输入治疗参数的图像处理器。 然后,图像处理器基于输入的治疗条件计算用于在心脏内执行治疗或诊断的安全区域和/或不安全区域。 图像处理器将信息叠加在屏幕上的图像上以识别安全区域和/或不安全区域。

    • The invention relates to the field of radiation oncology, specifically the use of novel radio-opaque fiduciary markers which resist migration within tissues, which may be implanted in the body and imaged during radio-therapy to insure accurate treatment of target regions while avoiding irradiation of non-target regions. In one embodiment, the markers comprise oblong bodies from which a plurality of short tines protrude. Also provided are novel devices for implanting such markers. Additionally, the invention provides methods of delineating tumor resection beds and whole-bladder contours in the radiotherapeutic treatment of bladder cancer. Lastly, the invention encompasses novel methods of delivering fiduciary markers and other implants and materials by needle with sealing aids that increase the retention rate of the delivered markers, implants, or materials.
