1. Maintenance refers to the process of keeping something in good working order, preventing it from deteriorating or malfunctioning over time. It includes tasks such as repairs, inspections, servicing, replacements, and other actions necessary to ensure the optimal functioning and longevity of a system or object.

2. Preventive maintenance is a planned and proactive approach to maintenance that aims to prevent equipment or systems from failing or breaking down. It involves regular inspections, testing, cleaning, lubrication, adjustments, and any other necessary actions to address potential issues before they become major problems. The goal of preventive maintenance is to reduce the likelihood of unexpected breakdowns, improve reliability, and extend the lifespan of equipment.

3. Non-scheduled maintenance, also known as unscheduled or reactive maintenance, refers to repairs or maintenance actions that are performed in response to an unexpected failure or malfunction. This type of maintenance is typically unplanned and occurs when equipment or systems break down or experience issues that require immediate attention. Non-scheduled maintenance is reactive in nature and aims to restore functionality as quickly as possible.

4. Scheduled maintenance is a planned and routine type of maintenance that is performed at regular intervals, often based on manufacturer recommendations or industry best practices. It involves pre-determined maintenance tasks, inspections, and replacements that are performed to prevent potential failures or breakdowns before they occur. Scheduled maintenance helps identify and address potential issues before they become major problems, ensuring the reliability and efficiency of equipment or systems.

5. It is important for developers to be checked daily to ensure the quality and progress of their work. Daily checks help identify any issues or bugs early on, allowing for timely resolution. Developers are responsible for writing code, creating software, or building applications, and their work directly impacts the functionality and performance of the final product. Regular checks also help maintain consistency and adherence to project requirements, deadlines, and quality standards. By checking the work of developers daily, any errors, inefficiencies, or potential problems can be addressed promptly, minimizing the risk of delays or complications in the development process.

6. The entire rack assembly must be checked regularly. This is important because the rack assembly plays a critical role in supporting and organizing various components or equipment. By checking the rack assembly, you can ensure that it is structurally sound, properly aligned, and free from any damage or wear that could compromise its functionality or safety. Regular checks also help identify any loose or missing fasteners, excessive vibrations, or signs of deterioration that may require immediate attention or maintenance.

7. Sensitometry and Densitometry must be checked periodically. Sensitometry involves measuring the response of a film or imaging system to different levels of radiation exposure, while Densitometry measures the optical density of a developed film. These checks are important to ensure the accuracy and consistency of radiographic imaging. By regularly checking sensitometry and densitometry, you can verify the proper functioning of the imaging system, assess film quality, and identify any issues that could affect the diagnostic quality of the images. This helps maintain image quality, improve patient care, and meet regulatory standards.

8. Exposure linearity must be within a certain tolerance for adjacent mA stations. Exposure linearity refers to the relationship between the selected milliamperage (mA) setting and the resulting radiation output. It is important to ensure that this relationship remains linear and consistent across adjacent mA stations. The specific tolerance for exposure linearity can vary depending on the equipment or regulatory requirements, but it typically falls within a certain percentage range. Maintaining exposure linearity within the specified tolerance ensures accurate and predictable radiation output, which is crucial for achieving consistent image quality and dose management.

9. The measured kVp should be within a certain tolerance of the indicated kVp. kVp (kilovolt peak) is an important parameter that determines the energy level of the X-ray beam. It is necessary to ensure that the actual measured kVp matches closely with the indicated kVp on the X-ray generator or control panel. The tolerance for kVp can vary based on equipment specifications, but it is typically within a specific range, such as +/- 5%. Maintaining accurate kVp measurements is vital to ensure consistent image quality, proper penetration, and appropriate radiation dose for different imaging exams.

10. Three measurement tools commonly used to assess focal spot size in radiography are:

a) Pinhole Camera: A pinhole camera is a specialized device that uses a small aperture to create a magnified image of the focal spot. By measuring the dimensions of the magnified image, the size of the focal spot can be determined.

b) Star Resolution Pattern: A star resolution pattern consists of a pattern of lines radiating from a central point. By imaging this pattern, the resolution and distortion of the focal spot can be assessed. The sharpness and clarity of the lines can indicate the size and quality of the focal spot.

c) Slit Camera: A slit camera is a device that uses a narrow slit aperture to create a line image of the focal spot. By measuring the width of the line image, the size of the focal spot can be determined. Slit cameras are often used for evaluating the focal spot size in mammography systems.
