| computer terminals | Input/output devices designed to receive data in an environment associated with the job to be performed, and capable of transmitting entries to, and obtaining output from, the system of which it is a part. (12 Dec 1998) |
|---|---|
| computer user training | Process of teaching a person to interact and communicate with a computer. (12 Dec 1998) |
| signal processing, computer-assisted | Computer-assisted processing of electric, ultrasonic, or electronic signals to interpret function and activity. (12 Dec 1998) |
| numerical analysis, computer-assisted | Computer-assisted study of methods for obtaining useful quantitative solutions to problems that have been expressed mathematically. (12 Dec 1998) |
| decision making, computer-assisted | Use of an interactive computer system designed to assist the physician or other health professional in choosing between certain relationships or variables for the purpose of making a diagnostic or therapeutic decision. (12 Dec 1998) |
| diagnosis, computer-assisted | Application of computer programs designed to assist the physician in solving a diagnostic problem. (12 Dec 1998) |
| drug therapy, computer-assisted | Adjunctive computer programs in providing drug treatment to patients. (12 Dec 1998) |
| image interpretation, computer-assisted | Computer systems developed to aid in the interpretation of ultrasound, radiographic images, etc. (12 Dec 1998) |
| image processing, computer-assisted | A technique of inputting two-dimensional images into a computer and then enhancing or analyzing the imagery into a form that is more useful to the human observer. (12 Dec 1998) |
| therapy, computer-assisted | Computer systems utilised as adjuncts in the treatment of disease. (12 Dec 1998) |
| user-computer interface | The portion of an interactive computer program that issues messages to and receives commands from a user. (12 Dec 1998) |
| analog-digital conversion | The process of converting analog data such as continually measured voltage to discrete, digital form. (12 Dec 1998) |
| angiography, digital subtraction | A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitised image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues. (12 Dec 1998) |
| annular part of fibrous digital sheath | One of the two circular fibrous bands of the fibrous sheaths of the fingers and toes attached to the shaft of the proximal and middle phalanges. Synonym: pars annularis vaginae fibrosae, annular pulley, annulus of fibrous sheath, ligamentum annulare digitorum. (05 Mar 2000) |
| radiography, dental, digital | A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from X-ray film or any other detector. (12 Dec 1998) |
