Who invented tomography mcq?
Emma Martinez Who invented Tomography? Explanation: In 1917, Radon invented the tomographic machine.
Who invented tomography *?
The first commercially available CT scanner was created by British engineer Godfrey Hounsfield of EMI Laboratories in 1972. He co-invented the technology with physicist Dr. Allan Cormack. Both researchers were later on jointly awarded the 1979 Nobel Prize in Physiology and Medicine.
Why contrast is used in CT scan Mcq?
Why is contrast used in CT scan? Explanation: The contrasts are usually of iodine based and get absorbed by the body. They weaken the radiation passing through the area of interest making white patches turn up.
Which of the following represent action potential Mcq?
3. Which of the following represents action potential? Explanation: Action potential has a magnitude of 20 mV. Explanation: Electric signals generated by the human body is known as ionic voltage or bio electric potential.
Which of the following represents telemetry?
1. Which of the following represents telemetry? Explanation: Telemetry is the process of accessing or collecting data from remote inaccessible points. Explanation: Telemetry is the process of data transmission which may include over any known modes.

21 related questions foundWhen did the Scada start?
Explanation: SCADA started in the 1960s. During this time the mainframe computers were used for the storage of data from energy plants, chemical plants, and other big industries.
Which transducer is known as self generating transducer?
Active transducers: Active transducers (self-generating) are those which do not require any power source for their operation. They work on the energy conversion principle. They produce an electrical signal proportional to the input (physical quantity).
Where are neurotransmitters released from Mcq?
(a) Neurotransmitters released by dendrites.
What principle does pulse oximetry follow Mcq?
4. What principle does pulse oximetry follow? Explanation: Beer-Lambert relates the emerging light with the concentration of the solution and the thickness of vial/object containing the solution. When light is incident on the solution, some of the light is absorbed.
How is the first action potential generated in the brain?
An action potential occurs when a neuron sends information down an axon, away from the cell body. Neuroscientists use other words, such as a "spike" or an "impulse" for the action potential. ... Action potentials are caused when different ions cross the neuron membrane. A stimulus first causes sodium channels to open.
What does the P in spect stand for?
d) P – orbital. Explanation: SPECT stands for Single Emission Photon Tomography. In this process, the radioactive dyes give out photons which are detected by the detector and forms an image.
What js a CT scan?
A computerized tomography (CT) scan combines a series of X-ray images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels and soft tissues inside your body. CT scan images provide more-detailed information than plain X-rays do.
Which radiation is used in CT scan?
CT imaging involves the use of x-rays, which are a form of ionizing radiation. Exposure to ionizing radiation is known to increase the risk of cancer.
Who invented CT scan and MRI?
But British engineer Godfrey Hounsfield came up with an improvement on the 70-year-old technology. It combined x-ray images with a computer.
Where was the CT scan invented?
The first commercially viable CT scanner was invented by Sir Godfrey Hounsfield in Hayes, United Kingdom, at EMI Central Research Laboratories using X-rays.
Who invented the first o2 saturation?
History. In 1935, German physician Karl Matthes (1905–1962) developed the first two-wavelength ear O2 saturation meter with red and green filters (later red and infrared filters). His meter was the first device to measure O2 saturation.
Who invented modern first commercially available pulse oximeter?
Dr. Takuo Aoyagi, a Japanese Bioengineer, whose pioneering work in 1974 led to the invention of modern first commercially available pulse oximeter, a life-saving device that clips on a finger and shows the level of oxygen in blood, died on April 18, 2020, at Tokyo, at the age of 84.
What is the purpose of oximeter in Mcq?
1. Pulse oximetry is used to measure the oxygen level in blood & heart rate. Explanation: Pulse oximetry is a technology used to measure the oxygen level in your blood and your heart rate.
Which is the longest cell in the body?
- In the human body, the nerve cell is the longest cell. Nerve cells are also called neurons that are found in the nervous system. They can be up to 3 feet long.
Which of the following is not found in axon Mcq?
8. Which of the following is NOT found in axon? Explanation: Endoplasmic reticulum is not present in axons as it does not synthesize protein. An axon contains mitochondria, neurofibril, and microtubule and the cytoplasm of an axon is called axoplasm.
What is purpose of Axon?
axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body.
What are transducers Mcq?
This set of Electrical Measurements & Measuring Instruments Multiple Choice Questions & Answers (MCQs) focuses on “Transducers”. ... Explanation: Mechanical transducers in general portray physical or mechanical signals at the output in response to any physical changes in a system.
Which is the inverse transducer?
The inverse transducer is the transducer which converts the electrical quantity into a form of non-electrical quantity. In other words, the transducer is a kind of actuator that has an electrical input and the non-electrical output.
Which is the active transducer?
Active transducer is a transducer, which converts the non-electrical quantity into an electrical quantity. Let us consider the non-electrical quantities such as pressure, illumination of light and temperature.
