Study Notes
Sonography
- Sonography uses ultrasound waves to create images of the body’s internal structures.
- Sonographers are diagnostic medical professionals who operate ultrasonic imaging devices.
- They create diagnostic images, scans, videos, and 3D volumes of anatomy using sound waves.
- Sonographers analyze the images to identify and diagnose medical conditions.
Brachytherapy
- Brachytherapy is a type of radiation therapy where the radiation source is placed inside or next to the area requiring treatment.
- This technique helps minimize exposure to healthy tissue during cancer treatments.
- Brachytherapy is commonly used for treating cancers of the breast, prostate, and other organs.
Teletherapy
- Teletherapy is a type of radiation therapy where the radiation source is placed at a distance from the area to be irradiated.
- The distance allows for controlled radiation delivery to the targeted area.
- Teletherapy is used for treating various cancers and conditions.
Software of Radiation Therapy
- DICOM (Digital Imaging and Communications) is a standard used in radiation therapy for blending PACS (Picture Archiving and Communication Systems) with other imaging modalities.
- DICOM enables easy sharing and management of medical images and patient information.
History of Radiation Therapy
- Emil Grubbe, an American physician, pioneered the use of x-rays to treat cancer in 1896.
- Marie Curie, in 1898, discovered the radioactive elements radium and polonium, which expanded radiation therapy applications.
- During the mid-1900s, cobalt and cesium units became widely used for radiation therapy.
- The development of linear accelerators in the 1940s significantly improved the effectiveness of radiation treatments.
- Godfrey Hounsfield invented the CT-Scan in 1971, revolutionizing medical imaging and diagnostic capabilities.
- IMRT (Intensity-modulated radiation therapy) and IGRT (Image-guided radiation therapy) advanced radiation therapy precision and effectiveness.
Radiation Therapist
- Radiation therapists assist radiation oncologists in delivering radiation therapy to patients.
- They accurately position patients for treatment and monitor them throughout the procedure.
- Radiation therapists adhere to strict safety procedures and maintain accurate records of patient treatments.
- They should be able to effectively communicate with patients and be compassionate.
