Medical Physics Services

The **Medical Physics department** at NORI provides specialized **Quality Assurance (QA)** services for **CT (Computed Tomography)** systems to ensure the accuracy, safety, and performance of these critical imaging devices. Medical physicists conduct detailed checks on the CT scanners to ensure they produce high-resolution images while minimizing radiation exposure to patients. This includes routine calibration, maintenance, and performance testing of CT systems to ensure they meet diagnostic standards and adhere to safety protocols. A key aspect of QA in CT is dose optimization. The Medical Physics team ensures that the radiation dose used in CT scans is kept as low as possible while still achieving the necessary image quality. This is done by fine-tuning protocols, monitoring patient exposure levels, and ensuring compliance with international guidelines such as those from the International Commission on Radiological Protection (ICRP). The department also tracks cumulative radiation doses for patients undergoing multiple CT scans, helping to further reduce unnecessary exposure. Additionally, the Medical Physics department carries out image quality assessments by testing parameters such as contrast resolution, spatial resolution, and noise levels in CT images. These evaluations ensure that diagnostic images remain clear and accurate, allowing radiologists to make precise clinical decisions. Through regular audits and collaboration with radiology staff, the department ensures that the CT equipment remains fully functional, efficient, and safe for both patients and healthcare professionals.

The **Medical Physics department** at NORI provides comprehensive **Quality Assurance (QA)** services for **X-ray** systems, ensuring that these essential imaging devices operate safely and deliver high-quality diagnostic images. QA procedures for X-ray machines include routine calibration and performance testing to verify that the equipment functions within the specified limits. These tests help maintain image quality, reduce the chances of equipment malfunction, and ensure patient safety by controlling radiation exposure. A critical aspect of the QA program is radiation dose management. The Medical Physics team ensures that the radiation doses used in X-ray imaging are optimized according to the **As Low As Reasonably Achievable (ALARA)** principle. They regularly assess exposure levels and make necessary adjustments to protocols, ensuring that patients receive the minimum radiation dose required for a clear diagnostic image. This involves close collaboration with radiologists and technologists to customize imaging techniques based on patient needs and clinical requirements. Additionally, the Medical Physics department evaluates image quality by checking factors like image contrast, sharpness, and the presence of artifacts. These assessments ensure that the X-ray images are reliable for diagnosis, which is essential for accurate medical evaluations. Through continuous monitoring, regular audits, and compliance with national and international radiation safety standards, the department ensures that X-ray imaging services at NORI remain both safe and effective.

The **Medical Physics department** at NORI provides critical **Quality Assurance (QA)** services for **mammography** systems to ensure accurate and safe breast imaging. Mammography plays a key role in early detection of breast cancer, so maintaining the highest standards of image quality is vital. Medical physicists conduct routine tests and calibrations of mammography equipment, ensuring that it consistently produces clear, high-resolution images needed for accurate diagnosis. These tests include evaluating factors such as image contrast, resolution, and uniformity. Radiation dose optimization is a central focus in mammography QA. The Medical Physics team ensures that the radiation doses used in mammograms are as low as possible while still providing high-quality images for diagnostic purposes. This balance is crucial since mammograms involve repeated imaging, particularly for women undergoing regular screenings. The department monitors radiation exposure levels, making adjustments to protocols and equipment settings as needed, and ensures that all procedures adhere to national and international radiation safety guidelines. Furthermore, the Medical Physics department regularly assesses the overall performance of mammography systems by testing parameters such as compression force, exposure levels, and image uniformity. These evaluations help to identify and address any potential issues with the equipment before they impact patient care. By collaborating with radiology staff and conducting frequent audits, the department ensures that mammography services at NORI maintain high standards of accuracy, safety, and reliability.
