PPT My spin on MRI The basics of MRI physics and image formation
2.6 Imaging Hardware. An MRI scanner is made up of four components: the magnet, gradient coils, r.f. transmitter and receiver, and the computer. In this section the general design and construction of these components is discussed. More specific details of the system used for the experiments in this thesis are given in the relevant chapters.

Mri system block diagram
The block diagram in Fig.I-1 shows typical interaction pathways between the major sections of an MR imaging system (3). At the present time a wide range of magnetic field strengths is available. Table l-2 shows some typical magnetic field strengths available commercially, ranging from 0.02 Tesla to around 15 Tesla.

Between the two, the key differences you need to be aware of are: T1 - ONE tissue is bright: fat. T2 - TWO tissues are bright: fat and water ( WW2 - W ater is W hite in T 2) T1 is the most 'anatomical' image (Figure 1). Conversely, the cerebrospinal fluid (CSF) is bright in T2 due to its' water content. T2 is generally the more.

Resultant magnetic field on the voxel. The longer the RF pulse is applied, and the stronger it is, the bigger the deflection of the net magnetic field, that is, the bigger the angle α. x-y plane. It can reach 90, or even 180 degrees. The bigger α, the longer it takes to recover when the RF is turned off.

Block diagram of an MRI imaging system. Static Magnetic Field MRI imaging requires the patient to be placed in a strong magnetic field in order to align the hydrogen nuclei. There are typically three methods to generate this field: fixed magnets, resistive magnets (current passing through a traditional coil of wire), and super-conducting magnets.

Magnetic Resonance Imaging (MRI) is a non-invasive imaging technology that produces three dimensional detailed anatomical images. It is often used for disease detection, diagnosis, and treatment monitoring. It is based on sophisticated technology that excites and detects the change in the direction of the rotational axis of protons found in the water that makes up living tissues.

Magnetic Resonance Imaging (MRI) is one way for healthcare professionals to look inside your body and see what is going on inside it without having to cut open your body.While there are lots of different ways to take pictures inside your body such as x-rays, computerized tomography (CT) scans, ultrasounds and so on, MRIs produce far more detailed images of the structure of a patient's blood.

resonance imaging (MRI), Part 1 How it works
Current diagnostic MRI scanners use cryogenic superconducting magnets in the range of 0.5 Tesla (T) to 1.5 T. By comparison, the Earth's magnetic field is 0.5 Gauss (G), which is equivalent to 0.00005 T. Cooling the magnet to a temperature close to absolute zero (0 K) allows such huge currents to be conducted; this is most commonly performed via immersion in liquid helium.

Magnetic resonance imaging can produce highly sophisticated and highly detailed images of the human body. Generally speaking, MRI scanning is excellent for visualising soft tissue - and so it is often used in the detection of tumours, strokes and bleeds.
