The inventor of the pre-detector collimator is not definitively created by a single person, but the concept of call itself is generally attributed to English business Henry cater who invented the floating commentator around 1825 originally used an astronomy applications -
Was discovered on November 8th 1895 by Wilhelm Conrad Röntgen in Würzbrug Germany -
It was discovered November 8 1895 discovered it on accident and named it x-radiation to signify an unknown type of radiation -
The focal spot is a concept and was created when the x-ray tube was by the same person. The dual focal spot was created in 1923 -
Godfrey Hounsfield and electrical engineer working at EMI had an idea was to use x-rays to multiple angles to create cross-sectional images of the body by reconstructing data with a computer performed in 1971 on a patient at Atkinson Morley Hospital -
The DAC imaging system that transforms the Digital data from the CT scanner into the analog signal that can be displayed on a monitor essentially allowing the visualization of the CT image on a screen it plays a crucial role in converting the raw data.The first Modern DAC chip was designed in 1982 burr brown research corporation the first release Delta sigma DAC was in 1989 General motors and IBM released in 1963 was a DAC – 1 -
The first CT scanner detector was a total multiplier detector used in the first CT scanner invented in 1967 by Sir Godfrey Hounsfield this first CT scan was of the human brain performed in 1971. -
A technique that limits the x-ray beam to a desired profile on the patient. The process of limiting the x-ray beam is called collation pre-patient uses an x-ray absorbing material within aperture to limit the x-ray beam the First procedure performed was a brain on a patient -
CT scans were first introduced in 1971 with a single detector for brain study under the leadership of Sir Godfrey Hounsfield and electrical engineer -
ADC is a CT scanner that uses an analog two digital converter to improve image quality and data acquisition

The first patient was scanned for CT on October 1, 1971. The scan was performed at Atkinson Morley Hospital in London on a middle-age woman with a Suspected brain tumor. The scan took 30 minutes and the data was processed for 2.5 hours on a mainframe computer. The images were captured with a Polaroid camera. -
A CT works by inducing a small proportional current in its secondary winding base on the current flowing through the primary conductor, allowing for safe measurements of high currents the measured current data is usually displayed on a digital interface, allowing users to see real time, power consumption and often providing historical data for trend analysis -
On Friday, October 1, 1971 a new procedure was performed to image a live patient’s brain after only the computer processing reconstruction delay. Image appeared on the screen other monitor, spark and revolution in medical imaging. -
A computer that processes, large amounts of data in parallel, making it powerful to certain types of calculations processors are used in CT scanners to filter acquired detector data in real time array processors can Significantly improve the speed of instruction processing they can improve the overall capacity of a system. They can provide extra memory for a system with low memory. The original paper study was completed in 1972 and the building of the prototype began in 1974 -
In 2000 Dickie proposed a microlens array shaping system that can improve the quality of an unknown multi mode laser beam. The multiplane light conversion was discovered in 2010 is a passive beam shaping technology that can combine and shape multiple light beams
