摘要： Analysis of electromagnetics for an antenna analyzes a current on a conductor having a junction between a linear conductor and a planar conductor relying upon a moment method. A planar dipole segment 9 includes a planar monopole 91-2 in which the current flows in the same direction as the current flowing through part of a quadrangle 41-2-4 of a radial segment 41, and a planar monopole 91-1 in which the current flows in the same direction as the current flowing in a planar monopole 35-1 of a planar dipole segment 35. In the vicinity of the junction between the linear conductor and the planar conductor, currents are expressed that flow through the vicinity of the junction where three segments consisting of a radial segment and two planar dipole segments are overlapped one upon the other.

The A/D converter includes a plurality of converting stages connected in a cascade form wherein each of the converting stages includes an ADC unit for converting an analog input into a digital output. The digital outputs from said converting stages form a conversion output. Each preceding converting stage except a last converting stage further includes an amplifier for deriving and amplifying a conversion residue representing a quantization error resulting from the conversion performed by the preceding converting stage based on the digital output outputted by the ADC unit of the preceding converting stage and the analog input inputted to the preceding converting stage. The amplified conversion residue from the preceding converting stage is supplied as an analog input to a succeeding converting stage. A connector is provided for connecting the amplifier of the preceding converting stage to a node in the ADC unit of the succeeding converting stage. The node provides a base voltage to the ADC unit of the succeeding converting stage.

摘要： A magnetic resonance imaging method and apparatus employing a pulse sequence including a periodically switched readout gradient and a phase encoding gradient to derive a series of echo signals. Prior to execution of the pulse sequence for acquiring data for imaging, a pulse sequence in which the phase encoding gradient is cancelled is executed to obtain information of deviation in position of echo peaks. Thereafter, a pulse sequence including the phase encoding gradient is executed and at this time, sampling start timings for echo data sampling in respective phase periods of the readout gradient are controlled according to the information of the echo peak deviation. Further, a phase difference between data of odd number echo signals and data of even number echo signals is compensated by rotating either of the data of the odd number echo signals or the even number echo signals by a suitable rotating angle to minimize artifacts.

摘要： In an NMR imaging method of distinguishing two chemical shifts of unclear spins and obtaining respective spin distribution images, 180.degree. RF. pulses are applied twice to generate two spin echoes after spins of an object for inspection have been exicted. In the second echo among them, a pulse time-interval is so set that the time difference between the Hahn echo and the gradient echo may provide two chemical shifts with a phase difference of 2n.pi.. On the basis of information representing the distribution of a static magnetic field included in an image obtained from the second pulse, an image obtained from the first echo is compensated. By using the compensated image, spin distribution images with two chemical shifts distinguished are obtained.

Four pieces of outer conductors and two pieces of ring-shaped inner conductors are capacitively coupled to each other through an insulator or an air gap. In the outer conductor(s) in at least one of a set of outer conductors disposed at positions symmetrical with respect to each other so as to form a first coil and a set of outer conductors disposed at positions symmetrical with respect to each other so as to form a second coil, a conductor member(s) for adjustment is attached in parallel to the arm portion(s) in that outer conductor(s) of that set. Alternatively, the arm portion(s) itself in that set is slidably attached to the wing portions in that set.
