Frank Shields Medical Equipment

Quality assurance (QA) refers to the engineering activities implemented in a quality system so that requirements for a product or service will be fulfilled. It is the systematic measurement, comparison with a standard, monitoring of processes and an associated feedback loop that confers error prevention. This can be contrasted with quality control, which is focused on process outputs. Two principles included in QA are: "Fit for purpose", the product should be suitable for the intended purpose; and "Right first time", mistakes should be eliminated. QA includes management of the quality of raw materials, assemblies, products and components, services related to production, and management, production and inspection processes.

Magnetic fringe field from the magnet can extend outside the room based on the set of magnetic field. The magnetic shielding which can be calculated based on the equipment and surrounding requirement, Shielding contains the field strength without the periphery of the room, thereby It can reduce the image quality issues due to moving magnetic permeable items around the MRI. Frank Shields uses passive shielding using magnets permeable mentioned on the walls, floors & ceiling partially or fully based on the site requirements. The final aim is to contain the 5 gauss line in a safe limit around the magnet. Shielding refers to the magnetic field outside the magnet bore. Passive shielding is the placement of heavy ferromagnetic plating in the walls or floor of the magnet room or even the magnet itself. This concentrates magnetic flux lines, reducing the fringe field beyond the shielding. Passive shielding (see also Faraday cage) significantly eases the problems of siting a MR Image in a confined space. Ferromagnetic objects are less prone to being attracted to the magnet, ancillary electronic equipment, credit cards and computer disks can be brought closer to the magnet and the MRI safety limit for pacemaker wearers (the 5 gauss line = 0.5 mT) is reduced from, typically, 10 m to 2 m from the magnet. A passive shield for a whole-body MRI magnet weights many tons. An alternative method of controlling stray field is active shielding.

A MRI cage or MRI shield is an enclosure formed by conducting material or by a mesh of such material. Such an enclosure blocks external static and non-static electric fields.Shielding is typically applied to enclosures to isolate electrical devices from the 'outside world', and to cables to isolate wires from the environment through which the cable runs. Electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as RF shielding.

Products used in Computed Tomography: Sedentex CT IQ: Within the body of the cylinder are features for the following tests; NoiseUniformity - The lower section of the phantom is uniform PMMA (density 1.20 +- 1.00%) Geometric Distortion - An array of 2.0 mm diameter, 3.0 mm deep Air gaps are uniformly pitched at 10.0mm intervals through one slice of the cylinder.Please click here to see the Data sheet. Sedentex CT DI: The SedentexCT DI dose index phantom comprises a stack of PMMA plates forming a cylinder representing the adult head. Several types of detector system are catered for: ionization chambers. thermoluminescent detectors (TLDs). gafchromic film. Please click here to see the Data sheet. TO CTDI: TO.CTDI permits the user to measure the dose index for computed tomography systems. The test object consists of two PMMA cylinders, one cylinder represents the head (160mm diameter) and the other represents the body (320mm diameter). The length of each cylinder is 140mm. Each cylinder contains holes large enough to accept a radiation detector, used to take the dose measurements. There is a hole at the Centre of the cylinders and one at each 90° interval, centered 10mm from the edge of the cylinder.Please click here to see the Data sheet. TO CTDI Plus: TO.CTDI plus permits the user to measure the dose index for computed tomography systems. The test object consists of three PMMA cylinders, one cylinder represents the pediatrics head (100mm diameter), the second the adult head (160mm diameter) and the other represents the body (320mm diameter). The length of each cylinder is 140mm. Each cylinder contains holes large enough to accept a radiation detector, used to take the dose measurements. There is a hole at the center of the cylinders and one at each 90° interval, centered 10mm from the edge of the cylinder. This item is available as a nested phantom (the pediatric head phantom fits inside the adult head phantom which fits inside the body phantom).

It is a wood core with laminated metal on both sides of the core. A vapor barrier is placed on the floor to isolate the shield from the ground. Frank shields has teams of professionals in many disciplines who will ensure...

Products used in Magnetic Resonance Imaging: MagIQ and MagIQ Duo: An image quality phantom for magnetic resonance imaging comprising a single chamber (MagIQ) or two identical chambers (MagIQ Duo) which may be filled with different solutions to create two test objects (e.g. high field and low field).
