    • For the purpose of enabling proper imaging of the prostate, a first saddle coil 210 having two loop portions of a geometry suited for sandwiching the lower abdomen of a human body from the anterior and posterior sides with the two loop portions facing each other, and a second saddle coil 310 having two loop portions of a geometry suited for allowing the lower limbs of the human body to be inserted into the two loop portions, and sandwiching the lower abdomen from the right and left sides with the two loop portions facing each other, are quadrature-arranged so that the phases of magnetic resonance received signals are different by 90°, thus achieving imaging of the lower abdomen of the human body with a high S/N.
    • 为了能够对前列腺进行适当的成像,第一鞍形线圈210具有两个适于从前侧和后侧夹住人体的下腹部的两个环形部分,两个环部分彼此面对, 第二鞍形线圈310具有适于允许人体的下肢插入两个环部分的几何形状的两个环部分,并且使两个环形部分彼此面对的左右两侧的下腹部夹持着, 正交排列,使得磁共振接收信号的相位相差90°,从而以高S / N实现人体下腹部的成像。

    • A chamber for exerting an ultrasound beam on a sample solution containing particles to be concentrated, separated or arranged is provided with a view toward arbitrarily controlling the shape of a spatial distribution of potential energy created by the ultrasound beam and concentrating, separating or periodically arranging the particles. In contrast to the chamber, irradiation ultrasound sources for generating ultrasound beams are provided to create an ultrasonic intensity distribution for producing a position potential energy distribution used to exert a force forwarded in a predetermined direction or a force staying at a predetermined region to each particle. Thus, a specific spatial distribution of potential energy can be realized by ultrasound beams each having a specific intensity, a specific frequency and a specific phase or an ultrasound beam formed by superimposing these on one another. Further, at least one suction hole for recovering separated solvents or particles is defined in a wall surface of the tube, which is orthogonal to the flow of the sample solution.
    • 在包含要集中,分离或排列的颗粒的样品溶液上施加超声波束的腔室设置有任意控制由超声波束产生的势能空间分布的形状的集中,分离或周期性排列 粒子。 与腔室相反,提供用于产生超声波束的照射超声波源以产生用于产生用于施加沿预定方向传递的力的位置势能分布的超声波强度分布或者保持在每个粒子的预定区域的力。 因此,可以通过每个具有特定强度,特定频率和特定相位的超声波束或通过将它们彼此叠加而形成的超声波束来实现势能的特定空间分布。 此外,在管的壁表面中限定用于回收分离的溶剂或颗粒的至少一个吸孔,其与样品溶液的流动正交。
