Description

Ultramicron nuclear magnetic resonance measuring instrument

Whether the utility model is a kind ofly to get muddled or the disorderly degree that takes place is judged the medical check and analysis equipment of sub-health state or morbid state by the detection of biological bulk wave.

As everyone knows, nuclear magnetic resonance imaging system is one of diagnostic device most advanced, the most expensive in the modern medicine image field.Be the Medical Devices that numerous scientists of states such as the U.S., Germany, Britain and Japan succeed in developing through many decades.

Magnetic resonance imaging MRI (Magnetic Resonance Imaging) carries out the new and high technology of imaging according to biosome magnetic core (proton) resonance characteristics that is shown in static magnetic field, its physical basis is the nuclear magnetic resonance theory, and its essence is a kind of quantum effect of transition between the energy levels.Experimental result shows, utilizes nmr phenomena can study the micromechanism of material.In view of the above, people encourage biological tissue with different rf pulse sequences, and with its relaxation of solenoid technology for detection or proton density information, Magnetic resonance imaging therefore occurred.

Magnetic resonance imaging is the important applied field of nuclear magnetic resonance, at present in order to guarantee the signal to noise ratio (S/N ratio) of NMR imaging, nuclear magnetic resonance imaging system must have extremely strong static magnetic field, thereby make this equipment to whether be equipped with in measured's body metal object require careful tight, image has the influence that is subject to multiple pseudo-shadow, shortcomings such as quantitative analysis difficult simultaneously.

For addressing the above problem, the purpose of this utility model provides a kind of on nuclear magnetic resonance theoretical foundation, and the pattern field source code that different tissues in the biosome is encouraged of utilization NASA exploitation is basic novel nuclear magnetic resonance measuring analytical equipment-ultramicron nuclear magnetic resonance measuring instrument.

Its feature is to have increased the high-sensitive Biont information self-regulated of ultramicron sensor-based system on the basis of existing equipment theory, can catch required faint electromagnetic wave in extremely faint biosome energy is also analyzed, its application mechanism has fundamentally changed the limitation that nuclear magnetic resonance high-intensity magnetic field radiant image in the past causes to the measured, but again partial detection calcification kitchen range and cortex of bone focus etc. at present nuclear magnetic resonance be difficult to be refined into the variation of the microscopic structure state of picture, simultaneously, the highly sensitive self-regulated sensor-based system of ultramicron has great data reproduction to the sampling of Biont information.Therefore, succeeding in developing of it not only can cooperate Magnetic resonance imaging equipment to do further quantitative analysis, but also can predict advancing of disease trend in a short time.

For achieving the above object, the utility model provides the high-sensitive Biont information self-regulated of a kind of ultramicron sensor-based system, its technical scheme 1 is characterised in that: by the control signal of CPU sequence circuit output, link to each other with the two-way input end that latchs integrated circuit U1 and U2 in the Drive and Control Circuit respectively, the output terminal of its two-way integrated circuit U1 and U2 is connected with RW2 with integrated resistor RW1 respectively, control sampling sensing circuit and sampling delay circuit respectively by the signal that the variation of integrated resistor is exported, different output signals by two circuit feed back to the input end of CPU sequence circuit through signal comparator circuit, thereby form the self-regulated sensor-based system.

The utility model is on the basis of technical scheme 1, and technical scheme 2 is that two-way latchs integrated circuit, it is characterized in that: the input end that two-way latchs integrated circuit U1 and U2 directly is connected with the output terminal of CPU sequence circuit by the bus of CPU respectively.

On the basis of technical scheme 1, technical scheme 3 is that two-way latchs integrated circuit, it is characterized in that: adopt two-way to latch integrated circuit U1 and U2, its output terminal is connected with RW2 with integrated resistor RW1 with the form of parallel connection respectively, to form the variable Electronic Control potentiometer of two-way output resistance.

On the basis of technical scheme 1, technical scheme 4 is that two-way latchs integrated circuit to the utility model, it is characterized in that simultaneously: two-way latchs the corresponding programme controlled variation of CPU of output signal of integrated circuit U1 and U2 and changes.

On the basis of technical scheme 1, technical scheme 5 is that the signal of the variation output of integrated resistor is controlled sampling sensing circuit and sampling delay circuit respectively, it is characterized in that: adopt the integrated resistor RW1 and the RW2 of two groups of different numerical value, the variation of its impedance latchs integrated circuit U1 with two-way respectively and the U2 variation of output signals changes.
