HISCOCK, Ch. J.

The petitioner became the proprietor of an X-ray laboratory which he desired to operate in the city of New York. Section 107 of the Sanitary Code of that city provided: "No person shall maintain, operate or conduct an X-ray laboratory * * * wherein radiographs are taken, diagnoses made or human beings examined or treated by X-rays, without a permit therefor issued by the Board of Health, or otherwise than in accordance with the terms of said permit and with the regulations of the said Board." Supplementary to this section the board adopted a regulation providing: "Every X-ray laboratory shall at all times be in charge and under the direction of a duly licensed physician or other person whose knowledge, experience and qualifications to operate and use an X-ray machine are satisfactory to the Health Department." It will be noted that these regulations provide for the operation of an X-ray laboratory for the purpose (1) of taking radiographs, or (2) making diagnoses, or (3) examining and treating persons by X-rays; also that such laboratory need not be under the management of a duly licensed physician but may be conducted by any "other person whose knowledge, experience and qualifications to operate and use an X-ray machine are satisfactory to the Health Department."

Petitioner made an application for a permit under these regulations to enable him to conduct a laboratory. His petition in effect states that the only operations which he desires to conduct are those of taking radiographs and not at all those of making diagnoses or treating patients and his formal application filed with the health department sustains this claim. The correspondence with the department of health on his original application for a permit and the affidavits filed in opposition to this application for an order of mandamus make it plain, as I think, that the department of health and the courts have proceeded on an entirely different and inapplicable theory in denying his application. This correspondence and these affidavits concede petitioner's experience and skill as an X-ray operator. They could not well do otherwise in view of the facts set out in his petition. They assume, however, that the petitioner proposes to diagnose and treat diseases of the spine; that his status as a chiropractor is not recognized as giving him any standing in the medical profession or any qualifications for diagnosing and treating diseases and that, therefore, his application should be denied.

As I have said this theory and view seem to be entirely inapplicable as a reason for denying the permit which petitioner desired. He did not propose to diagnose or treat, but only to take X-ray pictures and explain what those pictures show in the way of obvious physical conditions of the spine and which pictures would then be used if at all by some other person in connection with diagnosis and treatment. Certainly taking an X-ray photograph is not diagnosis or treatment nor do I think that mere explanation of what that photograph shows is diagnosis or treatment. An X-ray photograph would not show much to an ignorant and inexperienced eye. To one who is skillful and has understanding it would show a certain location or external condition of the spine, for instance, and I do not think that the explanation of what was thus shown would go beyond the limits of X-ray photography any more than the explanation of what appeared to be a blotch or shadow upon an ordinary photograph would go beyond the limits of ordinary photography. It may be conceded that the reading of an X-ray photograph would be a slight and necessary step in diagnosis and treatment but it would fall far short of what we understand by those terms which comprehend not only knowledge of a certain condition such as would be shown by the X-ray photograph but, beyond that, medical or surgical consideration of what may have caused the condition presented to the eye and of the treatment which ought to be given to it.

It rather seems to be the case that the authorities and the courts have so concentrated their vision upon the fact that the petitioner is a chiropractor of unrecognized standing in the medical profession that they have inadvertently overlooked the other fact that he is not urging his right to a limited permit because he is a chiropractor but simply because he is a concededly experienced and skilled X-ray photographer and, therefore, qualified as that "other person" mentioned in the Sanitary Code to take radiographs. The respondent could not arbitrarily reject his application. ( Matter of Picone v. Comr. of Licenses, 241 N.Y. 157.)

There being no question that the petitioner was entitled to have his application for a permit to operate a laboratory for the purpose of taking and reading X-ray photographs granted, and there being no dispute about the remaining facts and no demand by defendant or necessity for an alternative order, the orders appealed from should be reversed, with costs in all courts and an order made directing the issue of such permit, with ten dollars costs.
