Abstract: A current sensing noise thermometer comprising: a sensor resistor thermally coupled to a target to be measured; a superconducting coil; superconducting thermal breaks between respective ends of the sensor resistor and respective ends of the superconducting coil; and a superconducting flux sensor; wherein the sensor resistor, superconducting coil and superconducting thermal breaks form a loop inductively coupled to the superconducting flux sensor. There may be a noise filter between the sensor resistor and the superconducting coil.

Abstract: Described herein is a method to measure the position of the PET System using the MRI, through the use of MRI coils and fiducials. This approach offers a route to automated calibration which is more flexible than other approaches. This method of position measurement is useful for example in systems which have moving or removeable PET readout board systems or moving or removeable PET scintillator blocks.

Abstract: A system for controlling the temperature of a quantum circuit comprises an enclosure comprising enclosure walls made of temperature conductive material; a substrate for holding a quantum circuit; at least one source of cooling fluid; at least one port in the enclosure coupled to at least one source of cooling fluid; a control unit coupled to at least one source of cooling fluid and configured to control or enable the control of supply of cooling fluid to the chamber; wherein the system in use fills the enclosure with cooling fluid so as to cool the quantum circuit. Preferably, at least one source of cooling fluid is a source of 3He, 4He or a mixture of the two. The invention provides a method and system for optimising the operating temperatures of superconducting quantum circuits and processors and the environment they operate in.

Abstract: A system and method for time tracking and cost code allocation combines a graphical user interface slider with the concept of distributing time blocks across a selection of multiple cost codes. The slider provides a way for a user to distribute time across multiple cost codes according to the user's own assessment of where work efforts were more exactly performed on the job. The slider works independently but in direct correlation with each time block. A time block is somewhat “suspended” with regards to assigning a cost code to a worker's time and is distributed later using the slider.

Abstract: The present application relates to a magnetic resonance imaging system comprising: a magnetic resonance imaging device comprising a cylindrical gradient coil apparatus, a radio frequency coil apparatus configured to transmit radio frequency signals at a first frequency, and a first shielding apparatus comprising a first shielding layer arranged radially between the gradient coil apparatus and the radio frequency coil apparatus; and a patient table device comprising a table portion configured for a patient to lie on it, and a second shielding apparatus arranged around at least a portion of the table portion, wherein when the magnetic resonance imaging device is engaged with the patient table device, the first shielding apparatus is in electrical contact with the second shielding apparatus to form a cutoff waveguide which is capable of cutting off radio frequency signals at frequencies below a second frequency, the second frequency being greater than the first frequency.

Abstract: In order to improve both spatial resolution and sensitivity for brain research and clinical activity, we have designed a combined PET/MRI insert for brain scanning, referred to herein as a “BrainPET insert” that can be fit onto and into a suitable MRI system. The BrainPET Insert comprises, in order, a receive (Rx) coil positioned within and adjacent to a transmit (Tx) coil and a PET ring, wherein both the Rx coil and the Tx coil are within the PET ring.

Abstract: Described herein is a positron emission tomography (PET) detector array that has a plurality of detector elements, with each detector element mounted on a resilient, rigid support surface. A detector element movement system is connected to each rigid support surface, so that each detector element can be moved independently. This allows for the relative position of the individual detectors to be changed during imaging so that the imaging window can be increased or decreased during imaging, thereby allowing for improved, better resolution imaging of smaller volumes if desired.

Abstract: Apparatus for imaging during surgical procedures includes an operating room for the surgical procedure and an MRI for obtaining images periodically through the surgical procedure by moving the magnet up to the table. The magnet wire is formed of a superconducting material such as magnesium di-boride or Niobium-Titanium which is cooled by a vacuum cryocooling system to superconductivity without use of liquid helium. The magnet weighs less than 1 to 2 tonne and has a floor area in the range 15 to 35 sq feet so that it can be carried on the floor by a support system having an air cushion covering the base area of the magnet having side skirts so as to spread the weight over the entire base area. The magnet remains in the room during surgery and is powered off to turn off the magnetic field when in the second position remote from the table.

Abstract: An upper coil assembly for use with a lower RF coil assembly mounted to provide an RF probe arranged to be engaged with a head of a patient in MRI includes a plurality of coil loops arranged in a row defining a phase shift coil array with each coil loop including an independent output conductor for communicating signals to a respective preamplifier for independent amplification and each coil loop including a plurality of capacitors at spaced positions therearound. To decouple the loops each coil loop partly overlaps a next coil loop with a first decoupling capacitor shared on a common portion of each coil loop and each next coil loop. The first and third coil loops are also decoupled by using third decoupling capacitor in a connecting conductor between the first and third coil loops.
