Electrosmart is an Android application which measures the radio-frequency electromagnetic waves emitting from various sources like mobile phones (cellular networks i.e., 2G, 3G, 4G, 5G), WiFi access points, Bluetooth devices, etc. [2] The app uses the antenna of mobile phones to calculate the pollution of waves and order them according to the power of that particular source.
Other radiation therapy machines which incorporate real-time MRI tracking of tumors are currently in development. MRI-guided radiation therapy enables clinicians to see a patient's internal anatomy in real-time using continual soft-tissue imaging and allows them to keep the radiation beams on target when the tumour moves during treatment.

Use hands-free to decrease the radiation to the head. Keep the mobile phone away from the body. Do not use telephone in a car without an external antenna. The use of "hands-free" was not recommended by the British Consumers' Association in a statement in November 2000, as they believed that exposure was increased. [63]
Modern SPECT equipment is available with an integrated X-ray CT scanner. As X-ray CT images are an attenuation map of the tissues, this data can be incorporated into the SPECT reconstruction to correct for attenuation. It also provides a precisely registered CT image, which can provide additional anatomical information.
Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed (co-registered) image.
CT scanning can perform a virtual colonoscopy with greater accuracy and less discomfort for the patient than a traditional colonoscopy. [143] [144] Virtual colonography is far more accurate than a barium enema for detection of tumors and uses a lower radiation dose. [145] CT is a moderate-to-high radiation diagnostic technique.
At the same time as the announcement of the formation of the Open Handset Alliance on November 5, 2007, the OHA also unveiled the Android Open Source Project, an open-source mobile phone platform based on the Linux kernel. [2] An early look at the Android SDK was released to developers on November 12, 2007. [6]
Most radiation therapy is planned using the results of a 3D CT scan. A 3D scan largely presents a snapshot of the body at a particular point in time, however due to the time of the acquisition, in which the patient is likely to have moved in some way (even if only breathing), there will be an element of blurring or averaging in the 3D scan.
