Patient movements during radiotherapy
The British Journal of Radiology
|February 1, 1984
Abstract:
A system using closed-circuit television has been developed to enable the measurement of patient movements to an accuracy of 1 mm during external beam radiotherapy. The circuitry is under the control of a microcomputer, which records the movement data on magnetic tape for later analysis. The results indicate that patients mostly remain within 1 mm of their original set-up position on the treatment couch.

Radiological Investigation I: X-ray and CT
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
