The biomechanical influence of traction on the cervical spine.

The effects exerted on the cervical spine by a traction of 150 N was studied by means of an improved radiographic technique. The technique is presented together with results from a study including fifteen test subjects with and without clinical symptoms of neck pain. In a minority of discs a widening not exceeding 1 mm was seen. This widening was not correlated to presence of roentgen signs indicating degenerative disease of the disc nor to clinical symptomatology.

Adverse effects of stationary grids.

By means of simple tests, the mechanisms of image impairment due to stationary grids were demonstrated. Several contributing factors were found. The fact that the grid strips are not clearly visible in the film does not indicate that image quality is not lowered by the grid. To a certain degree it demonstrates that the image quality is so low that not even the grid lines are perceptible.

Intensifying screens in soft tissue radiography.

Certain screen-film combinations were tested in the low voltage range (26 to 40 kV, tungsten target) and compared with an optimal non-screen industrial film. The dose reduction was of no consequence as compared with the loss in image quality. Some physical properties of the screens giving rise to the failure are discussed.

Filtration in soft tissue radiography.

The influence of K-edge filters in combination with tungsten target tubes has been analysed in the low voltage range. It appears that these filters do not offer any advantages with this target material. Al-filtration, applicable to different types of soft tissue radiography of joints is discussed.

Influence of secondary radiation on image quality.

On the basis of observations concerning non-screen films and xerox plates a theory is proposed as to how the image quality is impaired by secondary radiation. The theory includes an explanation of why xerox plates and industrial roentgen films of a high silver content are less affected by secondary radiation than conventional roentgen films.

Soft tissue xeroradiography of the shoulder joint.

Soft tissue xeroradiography of the shoulder joint has been compared with a film technique arrived at previously. The xerox plates gave a lower radiation dose to the patient without loss of information. The film technique requires a tungsten target tube with an extra thin glass window (=0.5 mm Al), while the xerox technique may be used with standard tubes.
