A 12-lead surface resting electrocardiogram and posterior-anterior chest radiograph were recorded in all patients.
Reproducibility of set-up was then determined by comparing the daily portal images to the simulator verification radiograph.
The medical staff were asked to provide clear anatomical instructions or a diagnostic radiograph with the area to be treated drawn on the film.
The chest radiograph showed a "water bottle" configuration of the cardiac silhouette.
Subsequent chest radiograph at 3 years of age (b) reveals resolution of the lobar emphysema.
The chest radiograph showed severe kyphoscoliosis and a massively enlarged heart which almost filled the whole thorax.
Cardiac enlargement as observed on the standard chest radiograph is also more frequently detected in infants.
The electrocardiogram was normal, and the chest radiograph showed mild cardiomegaly with normal lung fields.
