    Books are no longer adequate means for storing clinical data in a form which can make retrieval sufficiently flexible. It is suggested that a Grouped Symbol Associator is the equipment of choice for relating an individual case to generalized accounts of many similar illnesses. It is further suggested that mechanical aids will provide the physician with precise knowledge in a systematic way and permit him to devote his time to a study of the individual peculiarities of a case.

    With the aid of a digital computer, comparison was made of hospital case data and data characteristic of hematologic diseases. The differential diagnoses of the hospital cases were tabulated in written form. Conclusions were also stated regarding whether enough hospital case data were present to establish a diagnosis, or whether additional data were needed. View full abstract»

  • An Analog Approach to Computer Diagnosis

    Publication Year: 1960 , Page(s): 247 - 248
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (392 KB)  

    The problem of diagnostic computation has been approached by defining each disease in terms of its symptoms and their relative significance in the characterization of that particular disease. These ``definitions'' were then converted into analogous resistive networks and were used as standards against which a group of symptoms representing an unknown disease could be compared. The specialized computer constructed for this purpose compares the unknown with each of the standards stored in the machine, and if there is a match it indicates with which standard or disease there is a match and to what extent a correlation exists between them. The machine compares the unknown with all of the standards even if a match is found early in the process so that if two or more possibilities exist they will all be indicated. View full abstract»

    Psychiatrists collect a vast amount of clinical information in lengthy interviews with patients. It is proposed that this information can be reliably recorded on a series of scales in a form suitable for high-speed data processing. A method of recording currently in use in a Michigan hospital is presented and its advantages and disadvantages discussed. View full abstract»

  • Major Problems in the Use of Computing Machines

    1) Medical histories recorded by machine. How will these records be used by medical people and medical institutions? The answer to this is important because at the moment no one has told us of a real bona fide use for these records, and consequently, having them in machine form is of no clear-cut advantage. 2) Machine-aided diagnoses. We feel that the computing machine can be of real service in this area, but it is not at all clear exactly how the medical profession can take advantage of the capabilities of the machinery. The real problem here is to use the computer to aid the doctor, not to replace him. 3) Laboratory data. Laboratory data can be fed into computers perhaps more easily than can any other data. However, it is probably going to be important to use laboratory analyzing equipment which can make records in machine-readable form if full advantage is to be taken of the computing machine. 4) The handling of graphical and pictorial information. such as ``EKG, EEG, and X-ray pictures.'' EKG's and EEG's can probably be made to yield to mathematical analysis, but the question of machine-digested X rays is still open. 5) Communication between doctor and computer. The question of how a doctor can introduce data into the computer without having to resort to the usual transcription of handwritten data to punch-card form is one that I feel we must settle if there is to be any progress at all in this area.

    A great many medical diagnostic tests have been developed to supplement the patient information obtained from history and physical examination. These tests vary greatly in amount of discomfort to the patient, complexity, and cost. It is obvious that diagnostic tests should be kept to a minimum. Logical consideration to help determine the minimum additional medical tests needed in a specific case will be discussed. View full abstract»

    Methods do not exist for the rapid, quantitative analysis of complex phasic patterns such as are seen on records of intraluminal gastrointestinal pressure or other parameters of motility. In an attempt to develop a more satisfactory method, these wave forms have been converted into digital form and then analyzed by the Whirlwind I digital computer at M.I.T. Generation of the autocorrelation function and the power density spectrum of these records has permitted a numerical, quantitative expression of certain information contained in these curves.

    The problem of retrieval of information from the large volume of clinical literature has received increasing attention in the last few years. The methods of structural linguistics are being applied to this problem and may ultimately provide for machine indexing and abstracting and for the flexible retrieval of data pertinent to specific clinical problems.

    The major activity of this laboratory is to establish mathematical models that approximately describe the various parts of the cardiovascular and pulmonary systems. With this knowledge descriptive equations can be derived that are suitable for solution by computer techniques. These solutions are of potential diagnostic value. Two examples will be cited in which 1) blood velocity is computed from a measured pressure gradient and 2) the physical properties of certain intrathoracic pulmonary structures may be deduced from air flow measurement.

    With the advent of modern, high-speed electronic digital techniques, new tools and new approaches to the problem of spectral analysis become possible. These can be used to develop methods for extracting this hitherto unused information from analytical systems. The resulting procedures which become available by the digital manipulation of spectral information provide a powerful extension of the analyst's ability and enhance judgment and intuitive knowledge built up by past analytical experience.

    It is becoming increasingly recognized that electronic computers can aid certain aspects of medical diagnosis. But to use the computer for such purposes, the mathematical foundation of the medical diagnostic processes must first be well understood. Three mathematical disciplines are inherently involved in the diagnostic processes: logic, probability, and value theory. View full abstract»

  • IBM Type 704 Medical Diagnosis Program

    The basic input to the type 704 computer is simply the presence or absence of those characteristics (symptoms or results of a laboratory test) of a set of medical cases which are considered to be pertinent by an expert in that particular field. Pairwise and over-all similarity of both the cases and the symptoms are defined so that geometrically the cases, considered as points in a suitable space, form several clumps, thus establishing a natural classification. The mathematical model is based on the assumption of equal-likeliness of the characteristics or symptoms so that in order that the final results be significant, a sufficiently large number of characteristics are initially assumed and the system is reduced by repetitively deleting the least significant characteristic, thus inducing weighting of the characteristics, since more emphasis is placed on those characteristics which comprehend one another. When the set of characteristics is fixed, the computer is able to determine the case or cases which in an over-all sense best represent the characteristics. By interpreting pairwise similarity as probabilities, it is possible to predict how likely it is for a case with given symptoms (or tests) to exist on the basis of the classification the computer produces.

    In machine-aided diagnosis, the problem of dividing the diagnostician's task sensibly between the doctor and machine will be a major part of any successful solution. In this division, a major problem to be faced will be facilitation of communication between the doctor and his mechanical aide. To study methods of communication to match ``communication rates,'' and to establish those parts of the diagnostic problem for which the doctor and machine are individually most suited, are probably the most important part of machine-aided diagnosis. On the solution of these problems rests not only the best realization of the potentials of the team, but, even more important, a full acceptance by the medical profession of the diagnostic machine as a welcome assistant.

    Computers have been built which can handle spatial problems. A particularly interesting application of the spatially oriented computer is to ``read'' chest X-ray photofluorograms and to separate the obviously abnormal chest films from the normal chest films. Preliminary studies of such a computer will be described. View full abstract»
