Abstract:
A method of magnetic resonance analysis of a specimen employing cylindrical coordinates comprisingproviding a support member having an RF pulse transmitting catheter antenna and RF pulse transmitting body coil means operatively associated therewith,imposing a main magnetic field on a region of interest of said specimen,effecting circumferential phase encoding by applying to said region of interest an initial RF pulse from said catheter antenna or said body coil means and subsequently applying an initial series of RF pulses alternating between said catheter antenna and said body coil means as the source of said pulses,employing receiver means to receive magnetic energy received from said specimen responsive to said RF signals and emitting responsive magnetic resonance signals to processing means, andcreating in said processing means a cylindrical coordinate image or chemical shift spectra of said region of interest by using information obtained during said circumferential phase encoding step.
