An endoscope is a device with a light attached that is used to look inside a body cavity or organ
In order for endoscopes to deliver images from inside the body they need, in addition to an image sensor, a light source, which usually consists of one or more LEDs. Both these two main elements accompanied by the microcontroller with the interfaces to the outside world also need a power supply.
MRT, CT and PET
Magnetic resonance imaging (MRI) and a combined modality including positron emission tomography (PET) and computed tomography (CT) provide whole-body tumor staging in a single session
Although these large devices contain many ASICs and various controllers based on embedded control platforms, various individual ICs are also required to implement motor control, positioning recognition, other sensors, lighting, etc.
An ultrasound machine creates images that allow various organs in the body to be examined
The machine sends out high-frequency sound waves, which reflect off body structures. A computer receives these reflected waves and uses them to monitor body structure image. For ultrasound sonograph devices there are special front-end ICs that act as pulse shape generators or switch between sending and receiving. Due to the high performance requirements in this application, dual-core application processors of the ARM9 class or even PCs are usually used to process the ultrasound data.With the separation of the signal processing and the signal analysis the entire analog part is housed in a separate box, which is connected via a USB interface to a PC, and in turn has an Ethernet connection.
Xray and Dental Xray
Dental X-rays help dentists visualize diseases of the teeth and surrounding tissue that cannot be seen with a simple oral exam
In addition, X-rays help the dentist find and treat dental problems early in their development. The signal processing of X-ray detectors is constructed using discrete components: Op-Amps and fast A/D converters. For image analysis a microprocessor is usually used in combination with an FPGA. In addition, each X-ray unit requires a power management system, a user interface (display, input unit) and communications interfaces, which are implemented either wired as USB or Ethernet interfaces, or wirelessly via Wi-Fi.
