服务 & 程序

 

与其他医生合作

We work closely with other physicians involved in a patient’s treatment to ensure integrated care. 我们定期提供报告，说明建议的治疗方法, 治疗期间的进展情况, 并在疗程后取得效果. 我们随时可以讨论病人的护理. 此外，查尔斯. 克里斯蒂癌症中心定期召开多学科肿瘤理事会会议, where our providers and other physicians involved in the a patient’s care meet and review their diagnostic information and make treatment recommendations.

 治疗计划的团队方法

Our doctor reviews all of the patients’ relevant diagnostic information (病理 reports, CT, 核磁共振成像, and 宠物 scans) and often confers with other specialists to help determine the extent of the problem and its suitability for specific types of radiation therapy. Our providers discuss treatment along with its benefits and risks with the patient and his or her family. 我们的物理学家, 放射剂量测试员, 辐射治疗, and doctor work closely together to develop the most appropriate treatment plan for radiation de肝y for each individual.

患者教育

癌症治疗的选择可能会让人不知所措. 在查尔斯W酒店. 科视癌症中心, our providers believe that taking time to educate patients on their disease and their treatment options helps them make the best decisions and reduce their fear and anxiety. 所有的治疗方案被提出，以便患者可以权衡每一个的优点. Our team welcomes questions from patients and family members during and after the initial consultation, 要么通过电话，要么经常在额外的会议上. Patients are given written educational material designed to teach them about their specific diagnosis and treatment and are often referred to outside reading sources and websites. 除了, patients receive personalized educational sessions with our providers and therapists to let them know what to expect, 遵循指示以尽量减少副作用, 并为饮食和其他支持提供辅助服务. 的 educational process continues during weekly visits with our provides once treatment has begun.

CT仿真

计划的第一步, patients undergo a planning CT (and sometimes 核磁共振成像 scan) of the targeted region in the position they will assume for the actual treatments. 正是在这个时候，定制的身体固定装置被创造出来. 规划的CT图像被发送到规划计算机站. Damore利用患者的诊断CT, 宠物, 以及核磁共振扫描来确定肿瘤的形状和位置. 经常, 将规划CT图像与诊断CT图像融合, 核磁共振成像, and 宠物CT images on either the Elipse planning system or the MIM system using special software. 的 doctor and the 放射剂量测试员 then use CT images to set up radiation beams that target the tumor and 形状 the radiation dose to conform to the target.

IMRT和3D适形放疗

我们用a 直线加速器 进行外部放射治疗. 的 直线加速器 de肝s beams of radiation that pass through the body to the cancer, 它在哪里摧毁癌细胞. 直线加速器能够传送 三维适形放射治疗, 它利用成像来确定尺寸, 形状, and location of the patient’s cancer in the body and tailor radiation beams using special shielding to target the cancer and protect normal tissue. 它还能够提供动态 调强放射治疗（IMRT）. This advanced technology uses a computer to shift small moveable leaves in the path of the radiation beam to vary the intensity of the beam. This tightly conforms the radiation doses around the target and further limits the radiation dose to normal tissue.

直线加速器是a TrueBeam (tm) (Varian corp), which is the most technologically advanced 直线加速器 available. 安装于2018年 TrueBeam (tm) 能够提供体积强度调节电弧治疗（VMAT） 或Rapidarc™, an advanced form of IMRT that de肝s a precise 3D dose distribution with a 360-degree rotation of the gantry. TrueBeam系统可以同步成像, 病人定位, 运动管理, 治疗交付.

电子门静脉成像

的 直线加速器 配备了 电子传送门成像装置（EPID） that de肝s real time digital X-rays of the treatment field to the Radiation 的rapists and physician while the patient is on the treatment machine. 的 team can compare the portal images with the images generated from the treatment plan in real time to verify 病人定位 and block shaping to enhance the accuracy of the treatment setup.

影像引导放射治疗（IGRT）

TrueBeam (tm) can also take kv X-rays at intervals during the treatment to verify the location of the tumor during treatment de肝y.

直线加速器配备了一个 机载成像（OBI） system that can take kV X-rays or low dose CT (CBCT) scans of the targeted area just before the radiation is given each day.

的 team then compares images from the initial treatment plan with the images taken just before treatment to see if the patient’s position needs to be adjusted.

在某些情况下, doctors will implant a tiny marker in or near the tumor to help localize the treatment area. IGRT ensures the patient and the tumor are in the same position as originally planned and improves targeting of the cancer and avoidance of normal tissue.

呼吸门控

的 TrueBeam (tm) 有能力 呼吸门控, which turns the treatment beam on and off during phases of the patient’s respiratory cycle. 这减少了治疗体积中正常组织的数量, 这样可以减少副作用的风险. 呼吸门控 对呼吸运动影响部位的癌症治疗有用吗, 比如乳房, 肺, 肝, 和腹部, 尤其是立体定向治疗.

立体定向放射治疗

This is a specialized technique that combines advanced imaging technologies with sophisticated computer guidance to de肝 highly targeted radiation beams that conform to the three dimensional 形状 and size of a tumor. Radiation is de肝ed at much higher doses compared to daily treatments in short course of therapy (usually one or up to five treatments) to destroy certain types of small tumors. 更高的精确度可以更好地保留正常组织, 辐射剂量越高，效果越好. Because this involves a high level of precision, special imaging and body immobilization are used. 最初用于在大脑中进行单一治疗（称为SRS）, 立体定向治疗现在被送到脊柱, 肺, 肝, 和其他部位（称为SBRT）在少数治疗中.

 放射性药物的治疗

Radiopharmaceuticals are medications that contain radioactive material that are de肝ed through intravenous injection or oral administration. 的 body absorbs the radioactive material through its normal metabolic processes and concentrates the radioactivity in specific organs. 最常见的放射性药物是I - 131（放射性碘）和RA - 223 （XOFIGO）。. 放射性碘用于治疗某些患者的甲状腺癌, 通常在手术切除甲状腺后. Ra-223是一种新的, 治疗转移性前列腺癌的创新方法, based on recent studies that have shown that it can make patients more comfortable and live longer with their disease.
