Steven Don has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230135766
    Abstract: A system or method for improving quality in projection and tomographic x-ray, which includes a depth sensing device to measure a depth of at least one body part of a patient from the depth sensing device and a control unit to calculate a thickness and/or circumference of the body part using the depth information. The calculated thickness and circumference information is used to determine an optimal level of x-ray exposure for the body part. The system or method also includes a camera to identify the body part that needs to be examined and to detect any motion of the identified body part.

  • Patent number: 7949098
    Abstract: A method of obtaining recommendations for lowered radiation dose for a type of radiological image, executed at least in part by a computer system, obtains at least one clinical image of at least one patient, taken under a baseline set of exposure conditions, as a basis image. Processing instructions related to image simulation under one or more reduced exposure conditions are obtained. The basis image is processed according to the processing instructions to generate a set of one or more simulation images, each simulation image representative of corresponding reduced exposure conditions. One or more simulation images are displayed to one or more diagnostic practitioners and an evaluation obtained from the one or more practitioners related to at least the quality of the one or more simulation images. At least one recommended reduced exposure condition is generated and electronically stored according to the practitioner evaluation.
