To provide a method for the formation of oxide films to form with advantage a high-quality oxide film having excellent uniformity in film thickness and film quality over the entire wafer. The method for the formation of oxide films comprises: the pretreatment process of forming a protective oxide film on the surface of a wafer positioned in a reaction vessel by performing oxidation treatment with radical oxidative species or an atmosphere containing radical oxidative species under depressurized conditions; and the oxide-film-formation process of forming an oxide film on the wafer by performing oxidation treatment at a predetermined temperature under depressurized conditions. The oxide-film-formation process is preferably performed following the pretreatment process in a continuous manner in the reaction vessel in which the pretreatment process is performed. The pretreatment process is preferably performed at a temperature lower than the temperature for the oxide-film-formation process and also preferably performed under depressurized conditions, the level of the depressurization being higher than the level for the oxide-film-formation process. A high-quality gate-insulating film for a transistor chip can be formed according to this method for the formation of oxide films.

Magnetic Resonance Imaging (MRI), which is given the acronym ULTRA (Unlimited Trains of Radio Acquisitions), can eliminate magnetic gradient reversals and allow simultaneous MR signal acquisition from the entire object volume in each of a multitude of very small receiver coils arranged in a 3D array around the imaging volume, except for gradient reversals and/or RF pulses for refocusing spins into echoes. This permits a rate of MR signal acquisition that is greatly increased (e.g. 256 times) compared with existing techniques, with a full 3D image constructed in as little as 1 millisecond. Furthermore, noise—both audible and electrical—is substantially reduced. The advantages over conventional MRI include:

• • 1. Clinical imaging can be completed in seconds or less, with good signal-to-noise ratio;
  • 2. Signal-to-noise ratio further increased by reducing or eliminating RF noise due to gradient switching;
  • 3. Real-time functional MRI on millisecond timescales;
  • 4. With single breath holds, high quality imaging of thorax and abdomen.
  • 5. Greatly reduced audible noise and vibration.
