Robert W. Rand, the only son of Carl Wheeler Rand, M.D. and Katherine Humphrey Rand, was born in Los Angeles, California on January 28, 1923. His father, Dr. Carl W. Rand, a respected neurosurgeon, was trained under Harvey Cushing, known to be the "father of modern neurosurgery."
Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer.
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
Then, gamma cameras capture and form two-dimensional [12] images from the radiation emitted by the radiopharmaceuticals. SPECT is a 3D tomographic technique that uses gamma camera data from many projections and can be reconstructed in different planes. A dual detector head gamma camera combined with a CT scanner, which provides localization of ...
A gamma probe is a handheld device containing a scintillation counter for intraoperative use following injection of a radionuclide to locate sentinel lymph nodes by their radioactivity. [1] It is used primarily for sentinel lymph node mapping and parathyroid surgery.
Total body irradiation (TBI) is a radiation therapy technique used to prepare the body to receive a bone marrow transplant. Brachytherapy , in which a radioactive source is placed inside or next to the area requiring treatment, is another form of radiation therapy that minimizes exposure to healthy tissue during procedures to treat cancers of ...
A gamma camera (γ-camera), also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy. The applications of scintigraphy include early drug development and nuclear medical imaging to view and analyse images of the human body or the distribution of ...
By using a gamma camera in nuclear medicine, the radiologist is able to determine if one of the four parathyroid glands is hyperfunctioning, if that is the cause of the hyperparathyroidism. Theoretically, the hyperfunctioning parathyroid gland will take up more of the Tc99m-sestamibi, and will show up 'brighter' than the other normal ...
