Intensifying screens are used in extraoral radiographic cassettes to reduce exposure time and dose for patients. DPT stands for Dental Panoramic Tomograph. Intra-oral film packets contain lead foil to stop the x-ray beam from exposing the film and causing unwanted exposure after exposing the film. Silver bromide is used in dental radiography as the coating on unexposed film which absorbs x-rays to produce an image. Radiographic monitoring badges should be checked regularly by an authorized company to check staff exposure.

CR involves capturing x-ray data digitally using an imaging plate, which stores radiation exposure information that is later read out by a laser and processed into an image. DR directly converts x-rays to a digital signal using a detector connected to a computer. The seminar discusses the components, principles, workings, advantages and disadvantages of each technology. It describes how CR imaging plates use photostimulated luminescence and how digital images are produced during plate reading.
Radiographic positioning of humerus and shoulder
The document describes various x-ray views of the humerus and shoulder. It discusses positioning, centering, and evaluation of anteroposterior, lateral, oblique, and axial views of the humerus. It also covers supine, upright, and stress views of the shoulder to evaluate fractures, dislocations, and other orthopedic injuries and conditions. Standard and specialized projections are outlined to demonstrate anatomy and identify abnormalities of the bones and joints.
Distortion
This document discusses two types of distortion that can occur in radiography: size distortion and shape distortion. Size distortion refers to unequal magnification and is influenced by the object-to-film distance and film-to-focus distance. Shape distortion occurs when there is elongation or foreshortening due to the central ray-part-film alignment. Magnification radiography can be used intentionally to visualize small structures and comes at the cost of increased patient dose. Proper technique such as parallel part-film alignment and perpendicular central ray direction can minimize distortion.

Some special imaging process
Xeroradiography is a method of recording x-ray images using a selenium plate that becomes conductive when exposed to light or x-rays. The plate retains an electric charge, allowing an image to form by applying developer powder to the charged areas. Two machines are used: a conditioner that charges and stores plates, and a processor that develops images on the plates by applying toner and transferring the image to paper. Copying radiographs involves producing a second image from an original, which can be smaller, the same size, or enlarged. Subtraction films are used in angiography to enhance vessel contrast by digitally subtracting a pre-contrast "mask" image from post-contrast images.
Radiology Contrast media and its Types
1. Contrast agents are substances that have different atomic numbers or electron densities than surrounding tissues, allowing visualization of internal organs on imaging.
2. Early contrast agents included barium sulfate, iodinated compounds, and air or CO2. Modern agents are classified as ionic or non-ionic monomers and dimers with varying osmolalities and viscosities.
3. Contrast agents are used with multiple imaging modalities like CT, MRI, ultrasound, and fluoroscopy. They are administered orally, intravenously, or directly into structures. The choice depends on the physical properties and safety of the specific agent and the anatomy being imaged.
Radiological contrast media

Dacrocystography and sialography
Dacrocystography and sialography are radiographic examinations of the lacrimal drainage system and salivary glands, respectively. Contrast medium is injected to outline the anatomy. Dacrocystography evaluates the lacrimal sac and nasolacrimal duct for obstructions, while sialography assesses the salivary glands and ducts for stones, strictures, or masses. Both procedures involve cannulating ducts, injecting low-volume contrast medium under fluoroscopy, and obtaining radiographs to identify any abnormalities. Potential complications are minor and include pain, contrast extravasation, or duct damage. Ultrasonography is now often used initially before resorting to invasive contrast studies
Portable n mobile unit
Portable and mobile radiographic units can be either portable or mobile. Portable units are small enough to be carried by one person for use outside of a radiology department. Mobile units are larger and mounted on wheels, able to be moved throughout a hospital. Both use an X-ray tube, generator, and control unit to produce radiographic images. Newer units are using high frequency generators, computed radiography, or direct radiography for more efficient and higher quality imaging. Mobile C-arm units are important for fluoroscopy in operating rooms.
Digital Radiography
This document provides an overview of digital radiography. It discusses the history, general principles, detectors, advantages, and disadvantages of digital radiography. Digital radiography was first developed in 1980 and makes radiographic images digitally stored and viewable on computers. The document focuses on the two main types of detectors used: flat panel detectors and high-density line-scan solid state detectors. Flat panel detectors can be indirect, using a scintillator, or direct, converting x-rays directly into charge. Digital radiography provides benefits like instant viewing, less radiation dose, and ability to share images digitally, but has higher costs than traditional radiography.
Chest x ray positioning
This document provides guidance on chest X-ray positioning and interpretation. It outlines different chest X-ray views including PA, lateral, AP, decubitus, and inspiratory-expiratory views. For a PA view, the patient faces the cassette with the tube 6 feet away. Proper inspiration is important, with the diaphragm at the 8th-10th posterior or 5th-6th anterior rib. Key areas to examine include the trachea, heart, diaphragm, lungs, pleural spaces, and bones. Paired inspiratory-expiratory views can demonstrate air trapping and diagnose foreign bodies.
Barium Swallow Presentation
This document provides information about a barium swallow procedure. It begins with an introduction and overview of the embryology and anatomy of the pharynx and esophagus. It then describes the procedure itself, including preparation, technique, views obtained, and indications.

This document describes a microprocessor-controlled transistor lead identifier circuit. It uses LEDs and binary logic to determine the base, collector, and emitter leads of an unknown transistor by forward biasing its junctions. The microprocessor applies logic voltages to the transistor's leads, observes which LEDs light up, and compares the results to lookup tables to identify the transistor's type and lead orientation. It can try different resistor values in case the initial results are ambiguous. The circuit provides an automatic way to identify transistor leads without needing to consult manuals.
Electronics for you (jan dec 2000)
This document describes a microprocessor-controlled transistor lead identifier circuit. The circuit uses LEDs and a testing socket to identify the base, collector, and emitter leads of an unknown transistor. It determines the transistor type (NPN or PNP) by forward biasing the base-emitter or base-collector junction and seeing which LEDs light up. It then identifies the collector lead by comparing the brightness of LEDs when the collector and emitter leads are swapped. The microprocessor compares the results to tables to determine the transistor orientation and outputs this on a display.

Projetos eletrônicos
This document describes a microprocessor-controlled transistor lead identifier circuit. The circuit uses LEDs and a testing socket to identify the base, collector, and emitter leads of an unknown transistor. It determines the transistor type (NPN or PNP) by forward biasing the base-emitter or base-collector junction and seeing which LEDs light up. It then identifies the collector lead by comparing the brightness of LEDs when the collector and emitter leads are swapped. The microprocessor analyzes the LED patterns to display the transistor part number and orientation. The circuit can handle various transistor types and packages by adjusting resistor values if the LED brightness is ambiguous.
