Hardcopy recordings of analog and digital images.

The increase in the use of various imaging modalities demands higher quality and more efficacious analog image recordings. Laser electronic recordings with digital array prints of 4K X 5K X 12 bits using laser-sensitive film or paper are being evaluated. Dry silver paper recordings are being improved and evaluated. High resolution paper dot printers are being studied to determine their gray scale capabilities. The authors have conducted a study to evaluate the image quality, costs, clinical use, and acceptability of CT, MRI, DSA, digital radiography, and radionuclide images recorded by the seven different printers (three laser, three silver paper, and one dot) in comparison with conventional film recording. This paper describes the technical developments and instrumentation of digital laser film and analog paper recorders and presents the results of our study.

Hardcopy recording technologies for digitally formatted image data.

The hardcopy recording technologies of video cameras, slow-scan (digital spot) recorders, and laser film printers are presented and compared. Slow-scan (digital spot) recorders offer a few advantages when compared with multiformat video cameras. But only laser film printers provide the high-quality hardcopy recordings and speed required by newer digital imaging modalities.

A new method of documenting hand cases.

A photocopier can be used as a helpful adjunct in the precise documentation of the condition of the hand. It is cheap and easy to use, and it provides a permanent and accurate record.

Ownership of the medical radiograph.

Current hospital policies controlling original diagnostic radiographs do not serve the best interests of either the patients or the institutions. A survey of 200 randomly selected hospitals shows that approximately 40% of the hospitals would not release the original radiograph directly to the patient. Even more important, hospitals will destroy original radiographs without prior notification of the patient. Although statutes and case law support the institutional ownership of the x-ray film, there is a strong legal trend allowing the patient the use of the film. There are potential problems with patient control of the original radiographic image, but there is no evidence that these problems would develop if current hospital policies were changed to allow the patient physical possession of the films. Because there are economic incentives for hospitals to destroy the original radiographs, hospital policies should be liberalized to allow patients to acquire and maintain possession of their own original radiographic images.

Upper respiratory irritation from controlled exposure to vapor from carbonless copy forms.

Exposure to carbonless copy forms has been associated with subjective reports of respiratory and skin irritation, but objective measurements of human reactions to exposure are lacking. Thirty workers with complaints of prior sensitivity to the forms were given brief, controlled exposure to vapors from carbonless forms and from bond paper in random, single-blind fashion. Nasal impedance increased 34% after exposure to carbonless forms (P less than .025) and rose 8% after exposure to plain paper (P greater than .10). However, frequency of symptoms did not differ between the two exposure modes, and was not correlated with the nasal measurements. Quantitation of nasal congestion by this technique may be a sensitive measure of short-term reaction to inhalation of irritants.

Taking a closer look: using deconstruction to explore recent Department of Health policy guidelines on copying letters to patients.

PURPOSE: This article aims to explore the value of deconstruction in the analysis of a health policy document. DESIGN/METHODOLOGY/APPROACH: Following a brief overview of the philosophy and concepts of deconstruction, the historical and political context of the document Copying Letters to Patients: Good Practice Guidelines is clarified. Deconstructive techniques are employed to systematically analyse the document, pursuing concepts such as the identification and exploration of marginalisation within the text; analysis of figures of self-reference; the revelation of asymmetrical oppositions within the text; identification of tensions and instabilities within the text; and analysis of ways in which the text suggests a difference in emphasis from the apparent primary intention. FINDINGS: Through utilisation of the key concepts of deconstruction, it is revealed how the policy document in question becomes freed from a passive acceptance of the words as fact, and its authority is brought into question. The masquerade of coherence and continuity within the article is dismantled and its inconsistencies and contradictions are exposed. The authors' stated attempts to prioritise the wishes and wellbeing of patients over the medical hierarchy are revealed as being subject to question and the influence of politics over health policy highlighted. ORIGINALITY/VALUE: This article reveals how, by using deconstruction as a focus, the linguistic means by which a text exercises its power can be interrogated and the ideological assumptions underpinning its production revealed. As such a new and informative perspective is added.
