About This Presentation

Description : Check out this medical PowerPoint presentation titled "Digital Imaging Equipment”.

This medical PowerPoint presentation is about digital imaging equipments which ares an essential part of modern healthcare. These devices use digital technology to create high-quality images of the body, allowing doctors and other healthcare professionals to diagnose and treat a wide range of medical conditions.

Some common types of digital imaging equipment used in healthcare include:

X-ray machines: X-ray machines use ionizing radiation to create images of the inside of the body. They are commonly used to diagnose bone fractures, lung problems, and certain types of cancer.
Computed tomography (CT) scanners: CT scanners use X-rays and computer technology to create detailed, 3D images of the body. They are often used to diagnose and monitor cancer, as well as to evaluate injuries and other medical conditions.
Magnetic resonance imaging (MRI) machines: MRI machines use powerful magnets and radio waves to create detailed images of the bodys internal structures. They are often used to diagnose and monitor conditions affecting the brain, spine, and joints.
Ultrasound machines: Ultrasound machines use high-frequency sound waves to create images of the bodys internal structures. They are often used to monitor fetal development during pregnancy, as well as to diagnose and monitor conditions affecting the heart, liver, and other organs.

Digital imaging equipment plays a critical role in modern healthcare, allowing doctors and other healthcare professionals to make more accurate diagnoses and provide better care to patients. However, it is important to use these devices safely and responsibly, as they can also pose risks to patients if not used properly.

Computed Tomography (CT)
Slide 3-

CT scanner
Slide 4-

Provides high-resolution cross-sectional anatomical images Table moves through a circular opening in the CT scanner called the gantry, while an x-ray tube emits x-rays as it spins 360 degrees inside the gantry A detector array measures the amount of x-rays that pass through the anatomic part and cross-sectional images are generated from data. How it works
Slide 5-

Detects and confirms the presence of tumor Guides a biopsy Helps plan and monitor radiation and surgical treatment Helps diagnose problems with blood vessels and the heart Used for diagnosing abnormalities of the: Brain, nasal passages, musculo-skeletal system, spine, abdomen, lungs and mediastinum uses
Slide 6-

Average scanning time per anatomic region is only 10-20 seconds therefore many patients can be examined under sedation instead of anesthesia General anesthesia and is necessary for thorax imaging to control respiration and for timed contrast imaging to control movement Ensures the clearest and most accurate images Other facts
Slide 7-

CT scans should be avoided during the first trimester of pregnancy Animals must be sedated or under anesthesia Risks
Slide 8-

Magnetic resonance imaging (MRI)
Slide 9-

MRI Machine
Slide 10-

Uses magnetic fields and radio waves to diagnose diseases and injury of soft tissue The atoms comprising soft tissue align with the magnetic field in the machine Radio waves pulsed into the field alter the atoms causing signals to be released and transmitted to a computer Signals then show up as either light or dark areas in the computer image How it works
Slide 11-

Primarily used to examine internal organs for abnormalities Imaging of large patients is limited to the limbs and head due to size constraints How it works cont’d.
Slide 12-

Diagnosing abnormalities of the brain, spinal cord, and musculoskeletal system Diagnose or monitor treatment for conditions such as: Tumors of the chest, abdomen or pelvis Certain types of heart disease Blockages, enlargements or anatomical variants of blood vessels Diseases of the gastrointestinal tract Cysts and solid tumors in the kidneys or other urinary tract organs uses
Slide 13-

Radio-frequency energy to excite molecules is similar to those from a radio or TV station Caution must be taken in patients with metal implants or pacemakers Requires general anesthesia to ensure the clearest and most accurate image possible . Risks

Slide 16-

Digital images are acquired at a rate of 1-8 frames per second The unit is used for myelography, contrast GI tract studies, and small animal general diagnostic imaging. how it works
Slide 17-

Special procedures such as angiography, venography, cardiac fluoroscopy, or evaluation for dynamic tracheal disease uses
Slide 18-

Only persons required for a fluoroscopic procedure should be in the room during the procedure Use the smallest possible beam area, thereby reducing the scatter radiation to personnel. Fluoroscopic doses can also be minimized by reduction in the fluoroscopic time used Use the shortest possible distance from the image intensifier to the animal to reduce scattered radiation levels. Safety while operating

Slide 21-

Computed Radiography uses a cassette system with imaging plate that contains photostimulable storage phosphors. The phosphors detect and store energy from the x-rays that strike the cassette. The light is captured, recorded, and processed into an image by a computer. The imaging plate is then erased by fluorescent light in the scanner, and is ready to be used again. How it works
Slide 22-

Digital Radiography has no processing or erasing step Provides an instant digital image similar to a digital camera How it works
Slide 23-

The digitized image can be manipulated: changing contrast and brightness, zoom in or out, and take measurements Images are stored in a secure file that is difficult to alter How it works Cont’d.
Slide 24-

Provides information about the internal architecture of abdominal organs, bones and areas such as the pelvic canal. uses
Slide 25-

Limit the X-Ray beam to the smallest area possible Align the X-ray beam properly with the animal and the image receptor Remain behind a protective barrier during the entire radiographic exposure Wear protective gloves and aprons having a lead equivalent of not less than 0.5 millimeter Safety While Operating
Slide 26-

Some radiographs require sedation or general anesthesia Risks
Slide 27-

Ultrasound
