摘要： An easily recognized spatial relationship between an object and a section thereof is displayed (together with a real time image of the section) to permit quick, accurate, easy and accurate selection of a desired three-dimensional position for the section. The coordinate system of an imaging system may also be concurrently displayed. In addition to sequentially pasted real time section images, a reference image acquired at an arbitrary time may also be pasted on a portion of the display. Thus a reference image and a real-time image of the scanned section can be displayed to facilitate a better spatial understanding of the position of the section being scanned and imaged.

摘要： Time-Of-Flight (TOF) MRI techniques are used to enhance blood flows into one of a pair of images for a given plane or slice of a patent's body. Arithmetic subtraction of such images produces a resultant image of substantially only blood flows since images of fat or other tissue are thus nulled out of the resultant image. All basic MRI sequences (e.g., FE, SE, etc.) can be used in conjunction with a pre-pulse on additional sub-sequences in a plane displaced from the objective plane to be imaged. Both arterial and venous blood flows can be imaged (separately or together in one resultant image). Color coding can be used in the resultant images to distinguish blood flow directions and/or velocities.
摘要翻译：飞行时间（TOF）MRI技术用于增强血液流入专利身体的给定平面或切片的一对图像之一。这样的图像的算术减法产生基本上只有血液流动的合成图像，因为脂肪或其他组织的图像因此被从所得到的图像中空出。所有基本的MRI序列（例如，FE，SE等）可以与从要成像的物镜平移的平面中的附加子序列上的预脉冲结合使用。动脉和静脉血流都可以成像（在一个合成图像中分开或一起）。可以在所得图像中使用颜色编码来区分血流方向和/或速度。

摘要： In a medical imaging method of taking a tomographic image of a sample into which a contrast medium is injected by the use of a medical imaging system, a monitoring operation is performed on the sample into which the contrast medium is injected and then an imaging scan for reconstructing the tomographic image is performed. The monitoring operation is to repeat the steps of: (1) performing a monitoring scan for collecting data representing a concentration distribution of the contrast medium in a monitoring region of the sample, (2) reconstructing a reconstructed image representing the concentration distribution of the contrast medium in the monitoring region from the data acquired by the monitoring scan, (3) calculating a maximum signal value from a reconstructed image newly reconstructed and the reconstructed image previously reconstructed every pixel and generating a monitoring image including the maximum signal value calculated every pixel whenever the reconstructed image is newly reconstructed, and (4) monitoring whether a start time of the imaging scan comes in, until the start time comes in.

摘要： In one embodiment, an RF coil device includes a base board, a belt member, a first coil element, a second coil element inside the base board, and a connecting unit. Both ends of the belt member are respectively connected to mutually separated places on the base board, so that the center part of the belt member is located on the anterior surface of the base board. The belt member is curved to form airspace between the center part thereof and the anterior surface for letting an arm pass through in interdigitation state. The first coil element includes first and second partial coils inside the belt member, and becomes a loop coil element by their connection. The connecting unit detachably connects the base board to the belt member, and mutually connects the first and second partial coils in the interdigitation state.
