Bicycle stress echocardiography can be used instead of treadmill. Bicycle exercise is particularly useful for patients with valvular heart disease or for evaluated pulmonary artery pressures. It is also used as a substitute for treadmill exercise testing when the heart performance at each stage of exercise needs to be assessed and the patient is capable of bicycle exercise. Bicycle stress echocardiography has no additional risk compared to routine exercise.

During a biopsy samples of body cells or tissue are collected.

In 1987 Esaote SpA began marketing its products in the United States through Biosound Inc.. In 1990 Esaote SpA acquired Biosound Inc.. Biosound Esaote today also distributes the veterinarian derivates from Esaote Pie Medical in the United States.

'BIOSOUND ESAOTE is an ISO9001/EN46001 certified major medical corporation operating as part of the international Esaote Group. With its parent company, Esaote, S.p.A. based in Genoa, Italy, ISO-9000 certified research and development and manufacturing facilities in Florence and Genoa, and North American headquarters in Indianapolis, the Esaote Group develops diagnostic ultrasound and magnetic resonance imaging (MRI) equipment for the worldwide medical community.'

Ultrasound Systems:

Biplane endorectal and endovaginal probes are commonly used in obstetrics, gynecology and urology. They are generally composed of 2 arrays one linear for imaging of the longitudinal plane and a highly curved one to image the transverse plane. These two planes allow a perpendicular visualization of the region of interest.
Ultrasound imaging in both transverse and longitudinal planes enables e.g., precise multiple biopsies by simultaneous visualization of both planes in real-time.

From POINT Biomedical Corp
BiSphere™ is a technology for drug delivery applications by ultrasound. BiSpheres™ consists of microparticles comprising a shell of an outer layer of a biologically compatible material and an inner layer of biodegradable polymer. The core of the microbubbles contains a filling gas, liquid, or solid for use in drug delivery or as a contrast agent for ultrasonic contrast imaging. The contrast agent particles are capable of passing through the capillary systems of a subject. The drug-loaded biSpheres™ would be administered intravenously and freely circulate throughout the body, while the drug encapsulated within would remain biologically unavailable. The drug would only be released when the biSpheres become flooded when passing through an externally directed ultrasound field.
The use of biSpheres™ to transport agents to specific sites within the body is expected to substantially increase local efficacy while decreasing systemic side effects or adverse reactions. The biSpheres™ may also serve to protect labile agents from metabolism or degradation. The noninvasive release of a protected, encapsulated agent can be controlled by ultrasound imaging to a depth of 20-30 cm from the skin surface.
The flexibility in size control in the biSphere™ technology has enabled the construction of submicron ultrasound contrast agents suitable for lymphatic imaging, with a diameter in the submicron range. This agent, while much smaller in size than CardioSphere®, is based on the BiSphere configuration: a shell within a shell enclosing a gas. The inner layer, made from a biodegradable polymer, provides the physical structure and controls the acoustic response. The outer layer functions as the biological interface. Each of these layers has been independently tailored to fulfill the specific requirements for lymphatic imaging.
