A noninvasive image measuring method of measuring internal organ / tissue temperature using an MRI system. Temperature measurement insusceptible to body motion and spatial variation of magnetic field is realized by utilizing the position and size of a temperature change region as a priori information to determine the phase distribution of the complex magnetic resonance signal of water proton at a given temperature point and by subtracting the phase distribution before the temperature change estimated (self-referred) from the phase distribution in the peripheral region for each pixel of the image, thereby eliminating the subtraction process of image before and after temperature change. The precision of temperature measurement can be enhanced by estimating a complex curved surface formed of the peripheral region in each temperature change region of the real-part and imaginary-part images of the complex magnetic resonance signal, and calculating the phase difference between an actually measured complex signal distribution and the estimated complex signal distribution of the complex signal distribution for each pixel, thereby reducing the estimation error due to phase transition from −π to +π occurring in a phase distribution. Furthermore, temperature can be measured through optimal imaging following up body motion by using an optical positioning system in combination even if the part being measured is shifted.

An artery, vein, aneurysms vascular malformation or arterial fistula is occluded through endovascular occlusion by the endovascular insertion of a platinum wire and / or tip into the vascular cavity. The vascular cavity is packed with the tip to obstruct blood flow or access of blood in the cavity such that the blood clots in the cavity and an occlusion if formed. The tip may be elongate and flexible so that it packs the cavity by being folded upon itself a multiple number of times, or may pack the cavity by virtue of a filamentary or fuzzy structure of the tip. The tip is then separated from the wire mechanically or by electrolytic separation of the tip from the wire.

A security checkpoint system and apparatus that provides security officers entrusted with protecting our nations' critical infrastructure or other high risk locations, a means of isolating and tracking suspicious persons who enter large public events or public transportation systems. Via a machine, communications system and components that are positioned at entrance points such as stadium section entrances, train station platform entrances, etc., a suspicious person entering the system is processed through a series of onsite as well as off-site follow-up investigations upon first being noticed as suspicious. The machine and it's overt security checkpoint system is designed to induce a suspicious reaction in persons with a guilty mind. As the person registers upon entrance to a facility, a close up view of the persons' face, as well as his seat assignment, is captured by the machine in digital image format. It is then sent by real-time transmission to security personnel in proximity to the location of the machine. A security officer positioned to spot persons manifesting suspicious behavior upon having to register at the machine, highlights the suspicious entrant electronically and sends an e-mail alert along with the digital images of both the suspicious entrant and his ticket, that also displays his seat number or destination, to on-site, as well as offsite law enforcement personnel for further review and investigation as necessary. As the system ties directly into the internet and can be sent to various law enforcement agencies for review, the resulting effect of such broad coverage of review of suspicious persons by law enforcement, makes this invention one of the most effective means of deterring terrorists and criminals in society today.
