From Philips Medical Systems;
Introduced in June 2005, 'one of the less expensive and more dedicated' ultrasound systems.

Handheld ultrasound systems are portable devices for smartphone or tablet and are increasingly common in emergency, intensive care and veterinary medicine, but also in the pocket of the stationary doctor. This type of ultrasound machine enables immediate diagnoses directly on site (handheld point-of-care-ultrasound / HPOCUS) and quickly provide information regarding the patient's further care. Handheld ultrasound machines fit into a single-use plastic cover and can be easily disinfected, making them particularly useful in infectious environments.
The most striking advantage of handheld POCUS devices is the small footprint. The design is very compact, lightweight (approx. 200 g/0,44 lbs. - 500 g/1,1 lbs) and flexible. Due to this compactness and the necessary technical compression, the quality of the imaging is still limited compared to 'high-end devices', but sufficient to the extent that handheld ultrasound devices are already successfully used in many medical disciplines.
Depending on the model, handheld ultrasound systems run on Android, iOS, Windows or proprietary operating systems. They are connected to the end device via USB cable or wirelessly via Bluetooth or WiFi. The respective end device is used as an ultrasound monitor to display the ultrasound images. The associated app is operated via touchscreen, although some devices have a few buttons, e.g. for recording ultrasound images or freeze images. The images can be stored and managed on the end device itself, the inserted memory card or in the cloud. Theoretically, also a private smartphone can be connected, but this can lead to complications with reimbursement.

From GE Healthcare.;
'The System of Choice for Shared Service.
The LOGIQ® 7 system provides a full range of clinical applications including abdominal, small parts, surgery, vascular and cardiac imaging and the power of GE's patented TruScan architecture. Just imagine an ultrasound system so versatile and reliable that it can meet the demands of virtually any clinical setting. And an ergonomic design that improves scanning comfort and clinical work flow.'

In June 2007 Tyco International Ltd. completed the separation of its healthcare business, which is named Covidien. Mallinckrodt, Inc. is now part of Covidien Ltd. The company makes and distributes products for respiratory care; bulk and dosage pharmaceuticals, primarily for pain relief and addiction therapy; and imaging agents for magnetic resonance, ultrasound, x-ray, and nuclear medicine applications. With worldwide manufacturing and distribution facilities and sales offices, Mallinckrodt, Inc. sells its products worldwide.
Albunex was one of the first marketed ultrasound contrast agents. Currently, Mallinckrodt discontinued the manufacturing and development of ultrasound contrast agents.

Ultrasound Contrast Agents:

(MIP) Angiography (Doppler) images can be processed by Maximum Intensity Projection to interactively create different projections. Although the maximum intensity projection (MIP) post processing algorithm is sensitive to high signal from inflowing spins as used in MRI, it is also sensitive to high signal of any other etiology as used in ultrasound imaging. The MIP connects the high intensity dots of the blood vessels in three dimensions, providing an angiogram that can be viewed from any projection. Each point in the MIP represents the highest intensity experienced in that location on any partition within the imaging volume.
For complete interpretation the base slices should also be reviewed individually and with multiplanar reconstruction (MPR) software. The MIP can then be displayed in a CINE format or filmed as multiple images acquired from different projections.
