Suggestions for viewing medical images?
Help viewing medical images: A college student with low vision is interning in in a radiology department and is having trouble viewing the medical images. Any suggestions? Here is his dilemma:
I have worked with the radiology department for only a few days and I have had some trouble with the x rays, CATScan and fluoroscopy. Specifically, I have had trouble differentiating between the white and grey images on the medical images because they are too close in the light spectrum. I have been able to see polar opposites such as the white bones on the black images, but it's harder for me to distinguish tissue or injuries because the colors grey and white on the medical devices are not polar opposites.
This article may provide some ideas, although it focuses on students who are blind rather than low vision:
Yoshida, T. & Ohtake, N. (2002). Making tactile charts on a personal computer for blind students in the allied health professions. Journal of Visual Impairment & Blindness, 96(5). http://www.afb.org/afbpress/newpubjvib.asp?DocID=jvib960508
Abstract:
Clinical lectures form the basis of acupuncture and physical therapy courses in Japanese colleges and universities. Medical images that are obtained by X-ray (Juhl, 1981), ultrasonography (Howry & Bliss, 1952; Kikuchi, Tanaka, Wagai, & Uchida, 1957), magnetic resonance imaging (MRI; Lauterber, 1973), and radionuclide imaging (scintigraphy; Anger, Mortimer, & Tobias, 1956) are an essential part of current educational programs. Regardless of the degree of an individual's visual impairment, knowledge of medical images is indispensable not only to allied health professionals but to students. In the old-style curriculum for students with visual impairments (those who are blind or have low vision), education in this area was either not required or was conveyed only by verbal explanation because the students had difficulty recognizing medical images. However, tactile charts can actively be used in medical education. The authors believe there is a marked difference in educational value between tactile charts and verbal explanation only (Yoshida, 1993, 1994). This article describes how to make tactile charts (see Figure 1http://www.afb.org/afbpress/pubjvib.asp?DocID=JVIB960508fig01) on the basis of medical images and how students who are blind evaluate these charts. Fortunately, most of the images are in black and white, with various shades of gray (gray scales). Thus, they can be converted to simple patterned tactile charts on the basis of certain defined rules.
