    • An ingestible pill platform for colon imaging is provided, designed to recognize its entry to the colon and expand in the colon, for improved imaging of the colon walls. On approaching the external anal sphincter muscle, the ingestible pill may contract or deform, for elimination. Colon recognition may be based on a structural image, based on the differences in diameters between the small intestine and the colon, and particularly, based on the semilunar fold structure, which is unique to the colon. Additionally or alternatively, colon recognition may be based on a functional image, based on the generally inflammatory state of the vermiform appendix. Additionally or alternatively, pH, flora, enzymes and (or) chemical analyses may be used to recognize the colon. The imaging of the colon walls may be functional, by nuclear-radiation imaging of radionuclide-labeled antibodies, or by optical-fluorescence-spectroscopy imaging of fluorescence-labeled antibodies. Additionally or alternatively, it may be structural, for example, by visual, ultrasound or MRI means. Due to the proximity to the colon walls, the imaging in accordance with the present invention is advantageous to colonoscopy or virtual colonoscopy, as it is designed to distinguish malignant from benign tumors and detect tumors even at their incipient stage, and overcome blood-pool background radioactivity.
    • 提供用于结肠成像的可摄取药丸平台,旨在识别其进入结肠并在结肠中扩张,以改善结肠壁的成像。 在接近外肛门括约肌时,可摄取的药丸可能收缩或变形,以消除。 结肠识别可以基于基于小肠和结肠之间的直径差异的结构图像,特别是基于结肠特有的半月形折叠结构。 另外或替代地,结肠识别可以基于功能图像,基于蠕形阑尾的通常炎症状态。 另外或替代地,可以使用pH,菌群,酶和(或)化学分析来识别结肠。 结肠壁的成像可以通过放射性核素标记的抗体的核辐射成像或荧光标记的抗体的光学 - 荧光光谱成像来实现。 另外或替代地,其可以是结构性的,例如通过视觉,超声或MRI手段。 由于靠近结肠壁,根据本发明的成像对于结肠镜检查或虚拟结肠镜检查是有利的,因为其被设计为将恶性肿瘤与良性肿瘤区分开,甚至在初期阶段检测肿瘤,并克服血池背景 放射性。

    • A photostimulable material is introduced in a blood vessel or body cavity, within an animal or human body, where a radioactive agent (comprising for example beta-emitting 32 P atoms) has been locally delivered and where radiation measurements have to be taken in order to control the delivery efficiency. The photostimulable material is exposed to radiation, carrying image information of the beta-emitting source of radiation, and a latent image is stored into the photostimulable material. Then the photostimulable material is exposed to stimulating light, which causes the photostimulable material to emit light in proportion of the amount of energy stored during radiation exposure, hence in proportion of the amount of radioactive agent present in the region of interest. The emitted light is collected by a light collection system and measured by a photoelectric device. Therefore, a two-dimensional image signal, representing the distribution of the radioactive agent in the blood vessel or body cavity, is obtained.
    • 将可光激励的物质引入动物或人体内的血管或体腔中,其中放射性试剂(包含例如β发射32 P原子) 已经在当地交付,并且必须进行辐射测量以控制交付效率。 可光激励材料暴露于辐射,携带辐射β发射源的图像信息,并且将潜像存储在可光激励材料中。 然后将可光激励的材料暴露于刺激光下,这导致可光激励的材料按照辐射暴露过程中所储存的能量的比例发射光,因此以目标区域中存在的放射性剂量的比例发光。 发射的光由光收集系统收集并由光电装置测量。 因此,获得表示放射性试剂在血管或体腔中的分布的二维图像信号。

    • An ingestible device, adapted to travel in the gastrointestinal tract and perform a diagnostic image of tissue therein, is provided. The diagnostic image may comprise diagnostic information as a function of time, or diagnostic information as a function of distance traveled within the gastrointestinal tract. Specifically, the ingestible device may be arranged to perform a diagnostic image of nuclear radiation of a radiophamaceutical, scintillation of a scintillation liquid, responsive to nuclear radiation of a radiophamaceutical, optical fluorescence of a fluorescing-pharmaceutical or of bare gastrointestinal-tract tissue, infrared radiation of the gastrointestinal-tract tissue, temperature-differences along the gastrointestinal-tract, impedance, ultrasound reflection, magnetic resonance, and a combination thereof. The ingestible device may be adapted for general screening of a large population, on the one hand, and for specific diagnoses of suspected pathologies, on the other.
