1 Imaging Informatics Telemedicine & Teledentistry Dr Ebtissam Al-Madi
2 Biomedical imaging informatics Is the study of methods for generating, manipulating, managing, and integrating images in many biomedical applications
3 Tasks of imaging informatics Image generationProcess of generating images and converting them to digital formImage manipulationUses preprocessing and post processing methods to enhance, visualize, or analyze the images.Image managementIncludes methods of storing, transmitting, displaying, retrieving, and organizing images.Image integrationThe combination of images with other information needed for interpretation, management, and other tasks.
4 Basic concepts Digital images Represented in a computer by a 2 dimensional array of numbers (a bit map).Each element of the array represents the intensity of a small square area of the picture called a pixel.Once pictures are in digital form , they can be handled (transmitted, stored, displayed and manipulated) like any data.
5 Basic concepts Imaging Parameters: Spatial resolution It is a measure of how well the imaging modality can distinguish points on the object that are close together.Is related to the sharpness of the image.It is the number of pixels per image.Contrast resolutionIt is a measure of the ability to distinguish small differences in intensity.It is related to the difference in measurable parameters such as xray attenuation.It is the number of bits per pixel.Temporal resolutionIt is the measure of the time needed to create an image.It can be real-time if the images are created concurrent with the physical process (30 images a second).

13 TeleHealthTelehealth is the delivery of health-related services and information via telecommunications technologies.Telehealth delivery could be as simple as two health professionals discussing a case over the telephone, or as sophisticated as using videoconferencing between providers at facilities in two countries, or even as complex as robotic technology.
14 Tele health Direct access to health information resources by consumers Consumer health related messagingRemote monitoringRemote interpretationVideo based telehealth
15 Types of Telehealth Telehealth: Telemedicine: Telecardiology refer to clinical and non-clinical services such as medical education, administration, and researchTelemedicine:telemedicine often refers only to the provision of clinical servicesTelecardiologyECG or electrocardiograph can be transmitted using telephone and wirelessTeleradiology;is the ability to send radiographic images (xrays, CT, MR, PET/CT, SPECT/CT, MG, US...) from one location to anotherTelepsychiatry:Allows anonymity of patient and less social stigma, physical examinations are not important.Correctional telehealth:Telehealth for prisoners in correctional facilitiesTeledentistry:is the use of information technology and telecommunications for dental care, consultation, education, and public awareness

17 Benefits of telemedicine Provides care for those living in remote areasProvides consultation, education and back up for specialists in remote areasDecreases costsBetter care in remote monitoring for patientsReduce visits to hospital and reduce congestion in hospitalsProvide help for patients in areas not able to be reached conventionally
18 Types of Telemedicine Store-and-forward telemedicine involves acquiring medical data (like medical images, biosignals etc) and then transmitting this data to a doctor or medical specialist at a convenient time for assessment offlineRemote monitoring:also known as self-monitoring/testing, enables medical professionals to monitor a patient remotely using various technological devices.Interactive telemedicine:provide real-time interactions between patient and provider, to include phone conversations and online communication.
19 Teledentistryusing the Internet to consult with an expert. This consultation could be:direct (between the patient and the expert)indirect (between the patient’s doctor and the expert).
20 Evolution of teledentistry Phone call to expertFax charts and recordsInternet: scanned image, digital image, and audio transfer of requests
21 Uses of teledentistryConditions that only visual inspection or history is needed for interpretationOral medicineChronic Facial PainAssisting patients with concerns:TraumaFinding a dentistSpecific organizations with urban and rural centers:MOH, KFSH, MOD, ect
22 Challenges and future directions Quality of information and content credentialingEnsuring provision of careLicensure of providersReimbursement of providersEmerging roles of health professionalsRobotics utilization
23 InteractiveMD is a telehealth company that connects patients with doctors via real-time videoconferencing, phone, and secure ,MDLiveCare is an on-demand telehealth company that provides patients with remote access via video, phone, and secure to board certified doctors and licensed therapists. Recently, the company partnered with Google Health to allow their users to sync the data shared during telehealth consultations with their online health records.
