Low-dose techniques refer to methods used in medical imaging and radiation therapy that minimize the amount of radiation exposure to patients while still achieving high-quality results. These techniques are particularly important in fields like radiology and oncology, where repeated imaging or treatment sessions can accumulate significant radiation doses. In radiology, low-dose techniques often involve advanced imaging technologies, such as digital radiography and computed tomography (CT), which optimize settings to reduce radiation without compromising image clarity. In radiation therapy, strategies like intensity-modulated radiation therapy (IMRT) allow for precise targeting of tumors, sparing surrounding healthy tissue from excessive radiation exposure.
