Computer and electronic data processing (EDP) programs are named software.

See also Hardware, Alpha Test and Beta Test.

The testing on software performed by the developers, usually during the development process; also, the first of several stages in the software testing process.

See also Beta Test.

A wide range of software techniques and advanced computer systems are developed that enable creation of three-dimensional images. Spiral CT allows the acquisition of CT data that is perfectly suited to 3D reconstruction. Advanced CT scanners image entire anatomic regions like the lungs in one breath hold and acquire a volume of data with the patient anatomy all in one position. This volume data is reconstructed to provide 3 dimensional pictures of for example complex blood vessels like the renal arteries or aorta. 3D reconstructions allow surgeons to visualize complex fractures in three dimensions and can help them plan reconstructive surgery.

The phase of software testing where a program or system is turned over to a select group of users outside the development organization for use in real-life situations.
