Q. What is autoanalyser?

Q. What is autoanalyser?

Ans: It is an instrument used for the estimation of various biochemical substances like glucose , enzymes, urea, cholesterol and proteins presents in the body fluids. Its working in controlled by a microprocessor.

Q. What is ultrasound imaging or sonography?

Ans :  It is based on the principle that when an electric potential is applied to the crystals of lead Zirconate, they get excited and start vibrating. These vibrations are the source of the production of ultrasound. These sound waves can’t pass through a vacuum. The ultrasound waves need a medium for propagation. The ultrasound waves can pass through the homogenous medium without any interruption till they reach a tissue or organ. From that tissue or organ, a part or the whole of ultrasonic wave is reflected back. These waves are received by the same leads zirconate crystals. When these ultrasonic waves reach the crystals, they are converted into the form of electric signal. This electric signal can be seen on an oscilloscope screen.

Q. What is computed tomographic scanning(CT)?

Ans: It is based on the application of x-rays. X-rays imaging is commonly used for the diagnosis of heart and lung diseases , for the detection of injuries and disorders of bones and joints, etc.

                Recently, the x-rays imaging is done with the help of computer tomographic scanning( CT) .In CT scanning a computer is used for reconstructing the image made by X-rays instead of being recorded directly on the photographic film. This technique is used for the diagnosis of the diseases of brain, spinal cord, chest, abdomen etc.

Q. What is pacemakers?

Ans: It is device implanted in the heart of patients for generating the heart beat. This is used when the heart beat drop to about 80-40 per minute due to any reason. This was first implanted by Chardack in 1960, It consists of a pulse generator and an electrode. The pulse generator is a sealed box containing lithium halide cells for providing  power for more than 10 years , and an electronic circuit to regulate the heart beat rate, etc. of the electrical impulse. The electrode is a fine metallic spring enclosed in a thin layer of biocompatible plastic . The electrode is connected to the pulse  generator  but its special tip remains in contact with interior of the right ventricles.
